We are now shipping from standing stock.

Updated details at https://bitcointalk.org/index.php?topic=637595.msg8961301#msg8961301 (https://bitcointalk.org/index.php?topic=637595.msg8961301#msg8961301)


We at Gekkoscience don't really like to do preorders. We've never done one before, because we much prefer to only take money from people when we can immediately ship them the purchased product. This time around though, we have to do things a bit differently and we're gonna try our best to make sure it's better for everyone.

We've assembled and successfully tested our prototype DPS-2000 interface boards, and we've contacted a few people who will be receiving a handful of boards in the next few days to use and test; we'd appreciate if some of them were to post reviews of the product so it's not just us talking about it.
The DPS-2000BB PSU requires a 240V input and is rated for 12V 165A output, but is capable of sourcing about 200A continuous. Our board is rated to handle 240A throughput. The board has 12 screw terminals per rail, so it can support 12 DC power cables without doubling up. The DPS-2000BB has no internal fans, but our boards have a 4-wire fan controller built in (with two 4-pin headers) for full-range PWM control of server-grade fans. The board also has the same pin header as our D750 boards, allowing external fan control, current sense output, 3.3VSB, 5V2A, POK, external turn-on, and current-share for load balancing.

(outputting a sustained 196A while powering four OC'd S1 and two custom-OC'd Cubes)

Development has been stalled so far, sometimes by other projects and sometimes by lack of funding, so we're behind on our expected timeline for the actual production run of these boards. We might have a single large customer, but we also have had a jillion people asking about these boards over the past couple months so we know we'll have a multitude of small orders as well, which must not be neglected.

Additionally convoluting the process, is this board will likely have two variants. I don't know how many people actually utilized the feature, but all of our D750 boards shipped with the ability to measure output current. We designed the same feature on the DPS-2000 board. Unfortunately the parts are more expensive, because it takes a different sort of hardware to compactly and efficiently measure 200A. Because of this, we'd like to offer a version of the board without current sense as well. Unfortunately that also sorta means either a lot of extra work during assembly, or a second run of PCBs. PCB pricing is heavily dependent on "economy of scale", sometimes to the point that an order of 25 boards actually costs about the same as an order of 100. So here's the plan, as we're thinking about it right now.


We'll offer preorders on boards, with the option to request any number of Current-Sense (CS) boards at $75 apiece, or Non-Current-Sense (NCS) boards at $60 apiece. Bulk pricing will apply for these, as seen in the price table at the bottom. General pre-orders for NCS boards will be open indefinitely, but CS board preorders will only be available for two weeks, ending June 17th. We'll require a minimum number of CS sales before placing the materials orders for those boards (probably at least 100), so if we don't meet that threshold we won't be offering CS boards. Anyone who purchased a CS board will have the option to either a) cancel the CS order and receive a full refund for the original amount paid, in the original currency paid, or b) transfer the order to NCS boards and receive a partial refund for the price difference based on the original amount paid, in the original currency paid, or c) transfer the order to an equal dollar amount of NCS boards based on the original amount paid, in the original currency paid, with the difference to be paid or refunded as negotiated.

As several other buy threads have done for things like this, I'd like to keep track of the current queue of orders based on First-Come First-Served, using a public list of what's been purchased using what currency. We'll be basing the BTC price off Coinbase sell-price exchange rate at the time of order, and we'll also accept PayPal transfers. All the funds will be held until after June 17th, at which time we'll determine whether we can make the CS boards or not. Once the initial preorder period has passed, it'll be 5 to 7 weeks before we start shipping boards, to allow for all the large parts orders to come in and we start production.

To respect our possible Large Single Customer, as well as all the preorder customers, we'll be dividing up the boards as they come off the line. If the LSC orders what amounts to 50% of the total order volume, then as boards come off the line, 50% of them will be held for the LSC and the other 50% will be shipped out to preorder customers starting at the top of the queue. That way the big guy still gets boards in a reasonable time (as we'd probably divide up shipments into smaller lots) and preorder people don't get stuck at the end of the line.

We're also working on cable supply, and will continue to stock and offer the standard 18" PCIe 6-pin 16AWG cables for $3.50 apiece. We'll also have 36" PCIe 6-pin 16AWG cables for $4.50 apiece.

Quantity	Price
1-5	$55
6-24	$52
25-99	$50
100+	$48

Shipping will have to be figured on a per-order basis. Up to 4 boards and 48 cables will fit in a Regional A box and ship for $10. Past that and we'll have to estimate a quote. For ordering info, either PM me or email sales@gekkoscience.com and make sure to include
1) your forum nick
2) the country we'll be shipping to
3) how many of each type board you'd want
4) how many of each length cable you'd want
5) if you'd prefer to pay with BTC or PayPal

So here's the deal. What do people think of that deal?

could you make one for: 379124-001-HP ML350/370 DL380 G5 1000W POWER SUPPLY ?

Not an official endorsement, but http://www.gigampz.com/index.html

That guy got to market while we were still perfboard-prototyping. We decided it wasn't worth our limited resources to try and fight him for market share when he had about a two-month head start. Maybe if enough people are interested, and someone gives us a couple thousand bucks to get started. We could maybe set up a similar preorder, with a minimum threshold of 250 boards total, but right now I don't even have a good per-board price estimate.

Big fan of your dell boards.

Would you consider selling preorder kits for this?  That is,  breakout board,  PS, and PCI-e adaptors?  Or would that needlessly complicate your life?

I'll have to check what power supplies we can get our hands on, but we basically are selling preorders on the boards and cables. Full kits, you run into the question of how many cables and what length.

Gotcha.  So you would just need the PSU?  Sounds good =)

We could maybe do a stock kit of 1 PSU, 1 board and 10 18" cables, then a super kit of 1 PSU, 1 board and 10 36" cables for $10 more. And if you want more than 10 cables per board you'd have to buy extra. I'll talk to our PSU guy and see what we can get our hands on, because having the PSU for sale would be pretty nice for customers. I just don't have a price range on those yet; we're mostly concerned about the things that are going to require money now for delivery in the future rather than things we get as soon as we pay for them.

interested in 1x CS and 7x NCS to Germany

I have sent BTC for a board and 12 cables...wondering if I could get some of the longer 36" cables for a little extra?

Thanks as always sidehack and crew.

*edit*...assuming the board hasn't already been shipped and sitting on my front porch when i get home...which in that case will promptly post a review of the product

Most of the beta boards shipped out yesterday. We should have gotten them out Tuesday. One of our bonehead engineers (well, me) based the fan header pinout on a fan we were using for testing and it made it all the way to PCB manufacture before anyone caught it (well, I did). So we wired up some adapters to fit on the fan header pins so actual standard 4-wire fans will mate natively. That slowed us down a bit. Thankfully that's the only problem we've identified with the board so far, everything else is working perfectly. r00t$, you'll probably see your box tomorrow or Saturday.

looking great!
just got 4 of these PSU's for £10 but cba to mod them if your board is out soon  ;D

what is the eta for shipping?
also what is the rough shipping cost to UK? (probably 3 or 4 NCS boards dependent on postage)

I know it sucks, but money doesn't grow on trees and the only way to keep the prices low enough that you guys can actually buy stuff is to order in bulk which takes a large initial sum.

ah completely missed that!
will mail you later with order when i know how many i will need

I've been pretty busy this week getting some stuff ironed out, but Saturday I'm going to take time and get back to everyone that's asked about preorders. So far no money has changed hands because I haven't gotten the tracking organization fully set up to make sure everything is accounted for accurately, but that'll all be done soon. Everyone that's emailed or messaged about orders so far should hear back from me by Saturday night.

Interested in this project.  I don't know if I can use the board right now, because the lack of equipment and the rental home I am staying in is an older home that probably could not handle the voltage requirements of the PSU.

Do you have posted any instructions/info on the proper use of the pins for these? Like, which pins are which for the fan header, what do the dip switches do, how to properly and safely configure for load balancing for 2/3/4 psu's, etc.? Also, for me, some of the pin labels are a tad hard to read due to the tiny font size. Could you post a pin-out for those as well?

One other thing...the pics posted show little chips between the top connectors and the terminal, but mine only have a bunch of solder. Is this because of the current sensing option, or because I have test boards? And which set of terminals is + vs -? I can't see any markings stating what is what on the boards.

Thanks.

The pin header and DIP switch operation is exactly the same as on the D750 boards, so glancing over the D750 V0.5 documentation on the gekkoscience website should fill that in. The chips at the connector are there for current sense, so NCS boards don't have them. It's high-side current sensing so the side with the chips/solderbridge is the 12V side.

You should also have received some pin header adapters, which the PCB accidentally has the 12V and GND pins on the fan headers fliped; the adapters fix that.

I received it Friday and very easily replaced 3 of the Dell Z750's I had strung up on my rack. SO much cleaner looking, and also better now that I got my mining equipment off my basement 110V circuit onto it's own dedicated 220V.

This baby hums along happily, although I don't know the total load I have on it, as my kill-a-watt meter is only 110V compatible. It's pushing a habanero (800W), some Drillbit bitfury boards (300W), some Avalon stuff (500W), and a whole mess of fans. None of the wires are warm to the touch. 

Having 12 power connectors on 1 PSU is the cat's ass..but I couldn't imagine doubling up on those spades. It's already pretty right in there with the 12. Beautiful job on the board.

Having fans in the right spot, and actually blowing through the PSU, is very important. I currently have 2 fans zip tied to the side, using the on-board fan header pins..one positioned right at the end where the breakout board connects, and one in the middle. Those seem to be the hot spots on the PSU. The pin header adapter actually worked out nicely for me by bringing the pins up off the breakout board a bit.

I'll try to snap some pics once I get everything wire managed a little nicer.

Excellent job Gekko Science team!

Thanks sidehack. The document had all the board info I was looking for.

We'll have actual documentation posted for that board specific one of these days. We're just much fonder of building things than doing paperwork.

so the 2kw supply has no fan and must be external? any links?

also how do you make 5v? the psu seems to not make much.

The PSU has no fans. Our board has an integrated 4-wire fan controller with two linked headers and full internal/external PWM control (from about 5% to 100% speed) so you can strap high-quality server fans to your PSU and not require any external stuff to regulate them.

5V is provided by an added 5V 2A buck regulator powered from the 12V output, same as on our 750W boards.

Sorry I didn't post anything regarding updates on the preorder. We're trying to work out a deal that'll get us up to a small run of CS boards that'll be made available, but Mystery Customer #2 has been foot-dragging for about a week and a half. We're scheming right now on the best way to move forward with smaller batches if we have to (which will mean a higher per-unit cost) to meet expected deadlines.

Sweet well I skipped this for my Neptune but I want a good power set-up for the future, I even got 240v installed at 30a so I'll want 4 boards later on to get 4 psus. Balance out 6kw

Are you doing the pwm? What's your temperature curve?

I wonder if 2a is enough for the knc control box

PWM is manually controlled by a potentiometer, or controlled externally with a voltage signal on the FAN pin like the 750W boards. To do temperature throttling would require an external thermostat circuit routing a control voltage into the board.

The buck IC is actually rated for 3A and beefing up the heatsinking on it shouldn't have a problem achieving that, but "officially" we rated the circuit for 2A. If I remember right from Block Erupter Overclock threads (which our buck driver is in the same family as the one used on the USB BE) there's another IC with the same pinout and 5A handling. You'd probably want to beef up the output capacitor as well if you expect to pull that kind of current, but it should be possible for a DIYer with basic surface-mount capability.

Thanks I guess buying a $20 regular psu for 5v ready for molex would be better and get 20a

So the fan has a knob, what should we run them at? Probably according to ambient in our location?

I don't really even worry and just run fans at full blast because I don't care about the noise. But setting them at some value and checking the heat of the PSU body and exhaust air, then iteratively adjusting to a working value that doesn't bother you, would probably work. I don't really have a "this PWM value works for this ambient temperature" graph handy because it depends entirely on fan size, placement and efficiency, as well as ambient temperature and power draw.

Cool if you get a chance some links to fans. Must they be pwm? Or can you do it via voltage too?

These look nice http://www.newegg.com/Product/Product.aspx?Item=N82E16835181040

Two-wire and three-wire fans will socket onto 4-wire fan headers but won't have speed control. I could have wired up an inline transistor to toggle the 12V line on and off but that puts artificial restraints on your fan choice and isn't a great way to do it anyway. I mean pulsed power (or DC-adjusted power) is okay for straight DC motors but kinda sucks for brushless DC. Most of the actual good fans are 4-wire anyway so that's what we support.

So, update. Large Potential Customers are dragging feet so we got fed up making everyone in the world wait and we're gonna do what we can to start without them. We're looking at assembling a batch of a couple hundred boards to be delivered in about 4 weeks. We're going to be doing Non-Current-Sense boards only, because we haven't had enough interest to merit current-sense boards (economy of scale and whatnot, you understand). We'll be gathering up funds for the next couple days and starting to place orders probably on Friday for PCBs. This'll probably be a 3-week turnaround so we should start shipping boards within 4 weeks to preorder customers.

Anyone that has requested information on preorders but haven't yet been able to give us money, it's probably because I still sorta hate preorders and wasn't terribly motivated to take money from people with no real guarantee of a delivery timeline (because of LPCs and whatnot). But we now have a fixed plan and we're gonna start rolling with it. We won't be offering CS boards at this time, but we will be gearing up for NCS boards and both lengths of cables in the very short term. I'll do my best today to catch up with everyone interested in preorders, and anyone else I may have overlooked or who was worried about delivery timelines, we Will Be (barring an act of God) shipping DPS-2000BB boards before the end of July.

PCBs have been ordered. If we don't get a couple more orders (or some other magic happens) in the next two weeks it's gonna be tight to get the batch done up, but we always deliver on our word. We figure at this point it's better to trust the community that's been telling us for months it wants these boards, than to sit around and wait for someone to come along and just hand us a bunch of money.

So we ordered the PCBs for the first big batch. About 35 are already spoken for, which is a really good start, but more orders wouldn't hurt. We expect to start delivering on July 25th.


We're also prototyping a little board which'll pull from a 6-pin cable and convert to an ATX 24-pin (with 2-3A capacity on 5V and 3V3), even with the ability to wire it up so the ATX_ON signal will kick on our PSU. That'll allow folks to use these DPS-2000BB natively in things which previously required bigarse ATX supplies for blades and controllers. One DPS-2000BB and two of those little boards could replace a pair of 1200W ATX supplies in miners. We'll have some prototypes probably early next week, they're likely to cost around $15 each and would work just as well on the D750 boards.

Sweet i think this is a impulse item, we dont know what kind of psu we need until very late so unless boards are ready to ship we just cant use you
Having stock will let you sell tons

Having stock is sorta dependent on being able to get enough of the rest of the parts to build them. Right now I can only guarantee that we'll be able to build enough for the current preorders.

If anyone needs the PSUs for these, we will be able to sell them for 45+ shipping, have about ~50 we can sell

What do you guys think... 3 or 4 S3 on one of these? 240v feed.

They'd probably do 5 or 6 without issue. We had four S1 and a pair of custom-hot Cubes on one, pulling just about 2500W for a solid week without even blinking. How many depends on what they look like overclocked, but if the stock numbers on Bitmain's website are to be believed, this thing could probably handle 7 at the top end.

That is perfect. I am thinking of stacking them 3 high and putting one of these in the middle for power. That will be OUTSTANDING.
Purchase email sent.

That's why we're gonna start stocking the 36" cables, to help power distribution setups just like that.

PCBs should be here on or before the 23rd, and we've got our sources pretty well arranged for the rest of the parts so there should be no delays getting the first batch preorders out. As always, preorders are appreciated because it'll help us get materials in larger quantities, which means faster more reliable turnaround for manufacturing and also building up standing stock for new orders. Right now I can only guarantee that preorders will be fulfilled; we haven't met the threshold yet to be able to complete the entire first batch. I don't like having to do it that way, but parts aren't free and we're a small outfit with not a lot of capital.

I've got 2 30A 240v circuits in the basement that I plan to stack with ~ 24 S3 units over the next handful of months.

These guys will make power a much easier proposition.


That will be a simple, sweet setup.

Indeed.

Additionally, anyone emailing about preorders, if you don't receive a response in the next day or so it's probably because for some stupid friggin' reason our server's been blacklisted (I think by Microshaft this time) and your host isn't taking our messages. Used to be an issue every time DNS updated, but we're on a static IP now so I don't know what they're complaining about this time.
If you're worried about a pending order status or anything, send me a PM and I'll let you know the score.

Any chance I could get some detailed specs/drawings or maybe a sample for these? I would like to design an enclosure for these boards.
I recently designed enclosures for the BlackArrow breakout boards https://bitcointalk.org/index.php?topic=645228.0

Thanks mate!

We don't have any sample boards left to ship out, but I'll see about putting some mechanical specs up on the product page on our website.

Awesome and thanks mate! Once I get a design whipped up and printed I can send you a copy for test fitment etc.

 Ok, my order for 200 chips through technobit has been confirmed. Can you tell me how many of the boards I will need? I will have 50 of the assembled boards. Also, do you have a good source for the PSU's?

To the guy wanting mechanical specs, we have some up on the product page on our website now.


50 of the Technobit minion boards? Nice. I have two coming. If I read right, that's a nominal 400W per board? If that's the case you could just get away with 6 per DPS2K but I'd probably plan for 5 per in case of overhead. 6x400W would put you about 94% capacity (which is to say, 14% over rated capacity), which I've tested one up to a little over 2500W continuous without issues but if the 400W is more than a 5% underestimate you'll be in trouble.
For powering 50 of the minion boards, I'd recommend 10 DPS2K setups. Your own configuration will determine what cable lengths and quantities you'll need. I don't have a lot of PSUs on hand presently, mostly just enough to test with and a few extras, but it looks like Minersource is starting to stock them in preparation for selling with these boards.

 It will be more like 500w once overclocked. So I am gonna take a shot and say I need 12-13 correct? If so, how soon can you have these made. BTW, I have ordered other items from you. :) Also I need a price for however many I need.

 I will also need 160 of the pcie cables with the connectors for the modules.

 So I am seeing around 50.00 each for the PSU's... Does this sound about right?

http://www.ebay.com/sch/i.html?_sacat=0&_from=R40&_nkw=DPS-2000BB+2000W&_sop=15

I seem to remember paying not as much for them but that was several months ago. bobsag3 said in a previous post that they've got around 50 they can sell for $45 plus shipping. I've not been able to get good word back from my usual PSU source about how many we can get ahold of to stock, or what prices look like.

These PSUs could still support 5 if they're right at or under 500W, but for safety (and marginally improved efficiency) it would probably be better to run 4 per. 50 would then require 13, or 12 if you did some clever load-balancing. At that range, you're in the second-tier price break of $57 per board. 160 cables would be $560 to $720 depending if you wanted 18" or 36" or a mix of both.


We're in preorder stage now for the boards; PCBs are expected to arrive about the 22nd and we'll have the rest of parts by then to start manufacture for shipping by the 25th. If you get in the queue right now, we'll probably be shipping your boards and cables on or before the 28th.

If you're interested in a purchase or want to discuss further, email sales@gekkoscience.com and we'll get you set up.

Awesome and thanks!

 I just remembered that the dell module came with cables. How many does this one come with?

The Dell set came with 4 cables if you bought a full kit. Most people were using them for two 2-socket devices, so it made sense. These boards will support 12 cables without overlapping (for six 2-socket devices, which is great if each device pulls 400W or less) but the more capable a thing is, the more options you're going to have (especially since we're stocking two lengths of cable) so we don't have a "standard package" with one board + x cables. Basically you just ask for as many boards and as many cables as you actually want.

Also we've gotten several people lately asking about hosting, which we've been considering for a while. The time to make decisions is now upon us, so we're looking for opinions.

If I may redirect the reader to https://bitcointalk.org/index.php?topic=622998.msg7814500#msg7814500 (https://bitcointalk.org/index.php?topic=622998.msg7814500#msg7814500) for a look at what we might be doing before long, and gather some opinions and try to gauge general interest.


Regarding the DPS2K preorder, everything is still on schedule. We'll be assembling the rest of the necessary parts this coming week, in expectation of PCBs arriving middle of next week and starting manufacture. Hopefully our cables guy can figure out a good pace and stick to it because we're gonna need a lot of them.

You still have some DPS2K breakout boards for sell?

with or without current sence?
What will be the total cost including shipping to EU ?

We have no current stock DPS2K boards available. The only option is preorder, and any orders placed now should ship on or before the 30th.

EU shipping for up to about 2 boards and 20 cables will be in the $50 neighborhood.

i need 1.. but maybe someone els would need 1 to in Eu (Netherlands), i PM him on ecointalk..

but you can put me in for 1

*watching*

Put me down for 2 please.

ok, payment sent for 1 and some cables.

Is there anywhere accepting BTC for the PSU itself?

$40 per PSU + shipping, have plenty. On hand now, and they work great with the proto boards I have gotten from sidehack

 Are they on the website? I do not see them. I need 13 please.

Not yet, I am going to put them up this afternoon

Sent a request for 6 NCS boards plus EU shipping quote to sales@gekkoscience.com. Definately no CS being made any more, right?

Any chance I can use the shipping paid for my X3, which is converted to chips sent from BA to Marto now, plus the paid extra PSU for the compensation unit, into store credit to buy these?

 Ditto.

Did you get anywhere with requesting this?

 I called them and they credited me with gift card and applied to my newest order.

Well folks, I got some good news and some of the other kind. The connectors just arrived, and the rest of the parts should be arriving tomorrow, exactly as scheduled.
The other kind of news, you might call it "bad news" is, that apparently giving the PCB manufacturer three weeks lead time on a not-large not-difficult order is apparently not enough because they just told us this morning that the boards (which should have shipped last Friday or today) aren't ready yet and won't be until the end of the week. So that schedule we had for when we wanted to start shipping things, we might not have the PCBs in hand by then. I am at least as displeased with this as you are, partially because it stacks on top of literally everything else we've been trying to do for the last week being delayed by slow and/or incompetent people outside our control.
Anyone that's talked to me about hosting miners in the last week knows exactly what I'm talking about.

So, a heads up. DPS2K boards will almost certainly NOT be shipping by Friday since we probably won't have the PCBs by then.

Thanks for the update, better a little bad than no news at all. Did my order came through okay?  

cheers

Thx for sharing,

Better to know the bad news than going BA style..

keep up the good work.

Yes, I've been out of town and/or fairly busy lately and haven't updated the public list but your order is paid and verified.

Regarding news, yeah I like to know when things change and figure my own customers would like to know as well. Because I promised a July 26th initial shipping date, it is my responsibility to let people know when that changes and for what reason. Y'all knew about ten minutes after I knew that there were going to be delays. We'll bust our butts to keep manufacturing time down and get orders out as soon as we can.

 Gimme a call man.. check your pms. :)

PMS? I'm a dude.

LOL

 I meant private messages :P

Check your own. Been waiting on a response since this morning.

Got my 2kW IBM PSU in today, its nice and compact.
Cant wait to connect the breakoutboard to it

Yeah it'd be pretty great if we started shipping those boards tomorrow. That'd be great. Board house is still a week behind though, but no more than a week so it won't slow us down too much. And to be honest, we just got everything ironed out with the lease on the shop so it gives us a few spare days to start moving stuff over and getting the electric install taken care of for hosting.

Wow, sounds like these could save me a lot of money on PSUs, all the efficient consumer grade PSUs cost a lot of money and it's been driving me crazy trying to source reliable and efficient PSUs without going bankrupt.  Only problem is that my data center has 208V but I have no way to testing whether the board is working at home before sending it to my data center and I don't wanna send over a non-working PSU.  Gotta figure out how to get 220V at home to test with, I have an air conditioner plug but I don't think it's the same kind of plug that these use.  

BTW so there's two four pin fan headers on these, so that's good for two fans right?  Is that sufficient to power this PSU?  Looks like most people mount some sort of 40mm server fan

I've had one running with a pair of 80mm strapped to it. I don't really have any smaller fans to test with but that setup has been working fine for a month and some.

All you really need is any cord that fits what your plug is, to a C19 end. Pretty generic.

iff order 2 server graded (high air volume) 40mm 4pin pwm fans (at full speed 13.000 rpm) those should keep the psu nice and cold

stupid question.

if you were connecting let's say 5 antminer s3's to 1 board.

would you use 18 awg or the 32 (or was it 38) awg pci-e cables ?

and why

If by "awg" you mean "inch", I'd probably get the 36". Five miners is a lot to stack around one PSU, and depending on how you're able to organize things, it's not easy to put everything within an 18" radius. If you have your organization planned out you could probably do some 18" and some 36", but the longer cables are only a dollar more and give you a lot more options.

If you're going to go more than 2 antminers stacked in any direction away from the PSU, you will need longer than the 18" cables.

With the 750/board combo, we have the PSU strapped to the top of a stack of 2 S1's.  the 18" cables reach the bottom of the 2nd S1, but with very little slack.  The 36" cables should allow for you to reach them 3 deep.

I have three questions ???

1) Can i make an order yet?
2) What is the diference between: Current-Sense(CS) and Non-Current-Sense(NCS)?
3) What it's your recommendation for 3 or 4 S3?

Thanks :)

We're still in preorder, since the daggum PCB house was well over a week late shipping our boards.

The difference between CS and NCS is NCS exists, but we decided not to make CS.

You should be able to run up to six S3 off a single DPS2K PSU.

sidehack. How are things going along?

I believe we received a shipping notification about midnight on Monday, which means the boards shipped basically a full week after they were supposed to have been delivered. Once those arrive we still have to populate and test them. We've been pretty busy all week getting the new shop set up, especially the hosting side, but hopefully we'll get that pretty much finished soon. If nothing else goes horribly awry we should be shipping boards next week. Pretty frustrated at the PCB house; we gave them a 3-week-lead order and it turned into a 4.5-week order. They told us two days after it was supposed to ship that it'd probably be shipping one week late and looks like it shipped later than that. Not impressed with their level of communication.

So, update. Apparently the shipping notification we got was for a different order that we didn't expect to ship until tomorrow. So, thanks a lot guys for getting us the stuff we didn't need early, and there's no evidence yet that the stuff we expected to be delivered a full seven days ago even exists yet.


Edit - they finally gave us a tracking number and the boards were delivered an hour later. So we're checking them over and should start shipping orders tomorrow or Friday.

Thx for the update,

Thats great news

Woohoo my box of DPS-2000BB's came in yesterday cant wait to test these puppies and migrate a bunch of miners. I'm going to use fans salvaged from damaged power supplies that are out of warranty or just not worth it to give some airflow to these puppies.

Thanks for all your work on these, after searching Alibaba for hours looking for cheap high quality +12V DC in masse my searches were fruitless.

Awesome news, thanks for the quick updates.

Great to here!

The first finished boards were shipped out today. We'll have a lot of stuff to do this weekend getting the shop set up and moving prep taken care of, so I don't know how many more will get made to ship by Monday but we'll do our best.

so how much for board and psu bundle?

Dunno, we're not offering one. Talk to minersource or something, they've got the PSUs.

so where is the best place to order here or the site for the boards and how soon could we expect delivery? shipping to the u.k.

We've got over a hundred boards pending in the preorder. Earliest we'd be shipping new orders is the end of the week. Everything else you need to know is in the first post.


Pardon if I'm a bit short or "snippy" lately. We had a really good timeline laid out but unfortunately everyone we were relying on for anything ever was between one and three weeks late, so now we're stuck with completing two different board production runs, and gathering for a third, and assembling all the cables, and preparing for a double move, and renovating a shop and building up an 80KW hosting infrastructure from literally zero, with the expected deadline for all of that actually already past. Oh and our entire workforce to complete it all is 2.5 guys, the other 1.5 of whom have wifes and, by extension, lives. So yeah, pretty busy. Not a lot of time to answer questions that have already been answered.

Lol I never knew you could hire 1/2 a man :)

http://en.wikipedia.org/wiki/American_wire_gauge

I don't think he means inch, dude.

I think he does. Read the context and then consider whether anyone ever would ask for ~36AWG power cables. I know very well what AWG means, but I'm also pretty sure I correctly answered his question.

brother i know EXACTLY how you feel, im on a 70kw facility and 2 guys down also. be as snippy as you want i like short cut answer. :)

It looks like we're gonna pull an all-nighter to get about 80 DPS boards out tomorrow, cables included. And the half guy will probably be coming in three hours early.

Thanks for the update. Looking forward to receiving these boards!

Id like 6 boards with cables. Where can I pay and total please.shipping to uk.

Order received today, thanks for the quick shipping! I won't have a chance to test them out for a few days but hopefully I can get 6 S3s at default freq off of 1 PSU.

Anyone have a calculation of home many DPS-2000BB can be run on a 30A 240V circuit?

30a x 240v = 7200watt/2000 = 3.6 round down to 3 :)

Yeah for 240V I'd recommend one DPS2K per 10A of circuit. If you don't overdrive them that should be enough headroom.

@ full power one PSU pulls about 8.6A (@ 238VAC)
2 PSU for same load is same AC load of 8.6A.

It is not how many PSU's attached to AC, it is the load on PSU's that is important.

EX: 4 2kW PSU for a 4kW 'load' would be OK as each PSU would be @ 50% of output power.

YMMV
:)

A couple questions:
Are you still taking orders for boards and cables?
Do you have the PSU's or do we get those separately?

Yes, we're still taking orders. We're still catching up to the preorders so we'd still be on "backorder" with approximately a one-week shipping delay, but we're still adding orders to the queue.

I don't have any PSUs. Minersource seems to have a good stock of them; I had someone within driving distance contact me about a pallet of 'em but they're holding out for approximately retail price and not really wanting to negotiate.

Thanks. Looks like you have to have a 200-240v circuit. That rules me out.

Yeah 2000-2500W is quite a bit of current to pull off a 120V line. 240V isn't really that hard to come by if you know how to work a breaker box. I sometimes forget though, that regular people often don't have the same skill set that I grew up with.

That's what youtube is for.  ;)

I prefer the being raised by an academician mother and a jack-of-all-trades carpenter father. Prepares you for all sorts of fun stuff, not the least significant of which are self-sufficiency and the ability to be useful in most any situation.

But yeah, if you didn't have that Youtube is a good fallback for on-the-fly instruction. I learned intarsia crochet from a youtube video one time.

That's fully loaded with 6x antminers per PSU, right?

In our setup we've got some APC 240v / 30a PDU's in the racks.  16A per bank or 24A total across both (2 banks per PDU).

I'm going to assume that if we make a "block" of 4x antminer per DPS-2000 we should be OK running 4 "blocks" per PDU?  In theory we'd be right around the max for the circuits but a hair under.  While we'd use more PSU's and boards, I think that would give us max density both in the cabinets as well as the PDU's.

Thoughts?

Consider the expected DC power draw of each miner, and sum for the total DC output of each PSU. Divide by 0.9 to get an expected input AC power requirement to make that DC output. Divide that AC power by your available mains voltage (208, 240, whatever) to ascertain your input current requirements.

Fully loaded these PSUs will output about 2500W, which requires up to 11.6A from a 240VAC source. At rated output 2000W it's more like 9.2A 240V.

If the S3 requires about 350W of DC power, four per PSU would be about 1400W of DC power, so about 1550W (max, should actually be lower than this as at 1400W the PSU efficiency should be more like 92-93% than 90%) which at 240V would mean 6.5A; a set of four of these would then be at most 26A of 240VAC. If the S3 requires less than 350W of DC power (all the numbers I've seen are "at the wall", which is a useless number if PSU efficiency is unknown) scale your required AC current accordingly.

Question regarding dip switch positions on the DPS-2000 breakout board ...I think I may have bumped one of the 3 dip switches because the fan controller no longer works. The fans I have strapped to the side are barely pushing any air through the PSU, despite adjusting the knob. Are one of the switches supposed to allow for the fan controller to function properly?

It's the same settings as on the D750 boards. We don't have a DPS2K doc up, but the D750 V0.5 doc on our website has all the pertinent information.

Sidehack, thanks for the tracking / shipping update.

do the psu's need the cooling fans attached like in the pic?

Yes, they need some sort of external cooling.  I just got my order of PSU's in yesterday.  Trying to figure out the best cooling solution, probably going to be some fans with lots of cable ties strapped to the side.

Anyone have any functioning solutions that are decent and recommended?

I've had one running with a pair of Delta 80mm zip-tied to one side. A lot of folks that used these supplies in high-dense installations would stack two and use a pair of 120mm zip-tied across both of them.

We're looking into feasibility of selling a full kit with 12x 36" cables, the PSU, the board and a pair of appropriately-sized fans in a bundle, so I'll also be doing research on the options here soon.

right ok thanks

Yep, the 2x stack with the 120mm fan is one of the options we are mulling, it seems to be feasible especially with the longer cables.

One question tho - is there a more optimal direction to have the airflow?  i.e. if the PSU is postitioned vertically with the plug to you, breakout board away from you, does it make a difference in the cooling if the airflow is from left-to-right, or the other way?

That's a question I don't have an answer for. Likely it doesn't matter, but someone that's studied the layout of an actual BladeCenter might be able to advise better.

Anyone know or have a server that used one of these PSUs? You could look at what direction the air flows in those.

These mount in the chassis. Not on the server.

Semantic nitpickery aside...

Just recieved mine, they look great! Thanks sidehack, looking forward to setting these things up once I'm back from vacation... :)

Anyone have an extra board handy? Sadly I cannot afford one yet...don't have a use for one either, I just want to further develop my 3d printed enclosure design for these and without a unit on hand, it's impossible to test fit.

I will gladly supply anyone with a couple enclosures once complete and the entire process should take less than 2 weeks, including shipping in both directions.

Thanks!

Send me a PM. I'd be willing to send you one of mine to test while i'm on vacation if I can get 2 cases out of it? Leaving tomorrow so I'd need to know today.

Just PM'd you my info. Going to up the ante and throw in a couple R-Pi cases and some other 3d printed goodies as well!
Thanks much, you rock!

 Need some help...

 I have received my 14 PSU's and awaiting the boards and cables. Sadly, I got no power cords with them, can you please point me in the right direction? I decided to go ahead and set up a new breaker box off my existing running 20 amp. Should I consider 30's? This should assure maximum efficiency. I now need power cords, fans to cool the psu's, and power strips. Any help is appreciated. I am going to be running 50 Marto Miners, and already working on another 50.

 Anyone who has advice, please jump in.

are you in u.k. and are you setting those up at home??

Got my cards yesterday. They look great!! Cant wait to fire these things up!!

Thanks sidehack!

No and yes.

If you are running new wiring for this, I would suggest:

30A 240V line (run 10/3 orange wire)

L6-30 twist-lock plug on the terminating end (dryer plug)

A PDU such as this (this is rackmount, they make other form factors):  http://www.cdw.com/shop/products/Tripp-Lite-PDU-Basic-208V-240V-30A-4-C19-16-C13-L6-30P-Horizontal-1URM/759513.aspx

Cables such as this:  http://www.showmecables.com/product/c20-to-c19-power-cord-1-ft.aspx?utm_source=google&utm_medium=cse&utm_campaign=44-105-001&zmam=49733141&zmac=5&zmas=1&zmap=44-105-001&gclid=CNWzg6bog8ACFaVZ7AodOHEA9Q

Oh, and BTW - to power all 14 PSU's to capacity you'll need fresh 200A service, minimum.  I'm basing this off of sidehack's post a few back of each PSU running roughly 12A at full load, if my math is correct.

It's by no means a permanent install and not to code, but for temporary setup (that's been running fine for two months) I ran a 20A breaker, 12/2 wire (line, line, GND) into a 3-gang of standard 5-15R outlets. They're not rated for 240V but everything's working fine and the current from a single PSU shouldn't overload contacts, especially if you operate around the midrange of the output instead of peak (and by "peak" I mean 120% rated that it can actually do). If I'm thinking right, 50 martominions across 14 PSU will draw around 6.5-7A per PSU on a 240V line so basically any consumer socket will work. If you want to go fancy (and probably more reliable) use that guy's PDU, otherwise hit up the Home Depot and make your own for about $20. If you're using 30A circuits though, definitely run at least 10AWG wire.

You'll be looking at drawing around 100A of 240V to feed all those miners. Make sure that's possible with the power service you have available.

As a comparison my home only has 100 amp service from the utility. I'd expect a visit from the police too if you are drawing 100A in your home.

Xcel [I and maybe? nexus99's power provider] actually called us to ask about our power use when we were running 15 ants per apartment this winter, but we also have a bunch of high end cops, but once we told them it was for miners we never heard from them again

More orders shipped out today. We're waiting on some 18" cable parts to come in but the rest of the orders currently pending should ship out on or before Tuesday if everything goes as planned. After that we'll be focusing on moving and getting the shop set up, especially fleshing out the hosting side and getting benches back up.

 Thanks again guys for the input. Here is what I got today. My electrician suggested instead of outlets why not run the cable directly to the connector plug and you can move it as needed. He also had me buy the SJ instead of SO that way it meets code as well. So the 4 30amp circuits should support 16 PSU's if I am reading this right.

 Also, My Main Breaker for the house is a 200 amp service. I have already informed the wife that the oven and dryer will not be used at the same time. I am converting my existing 48 gpu farm into 240v as well and will be moving it to another site. My cointerras will be moving as well. That brings up another point. So long as I connect these psu's to the main board of the cointerras, one could run both machines correct? They pull around 500w per board, but I have a dead board so 3 boards should be fine on one PSU instead of the 4 I have now.

 Please tell me anything you see as a problem to this point. I still haven't figured out the tripplite situation as of yet. Nor the power cords for the PSU's. What gauge is need for those?

 http://imgur.com/a/XRc6l (http://imgur.com/a/XRc6l)

 I am thinking these are perfect....

 I have 3 45u racks. Which were bought to accommodate rack mountable gear. Example.. I bought 10 1M5 miners from ltcgear and they were never delivered. I have since traded them in for shares and he pays me weekly for them. Also I bought 2 x3's which would have mounted but now I am going a different direction. I am looking at a way to incorporate the racks to marto miners. Sadly, till I have my hands on them, I cannot make anything. :(

 Keep it coming guys, your advice is more than appreciated.

 Scrap'

 To add to this. We never once had to turn the heater on in the house last year and it got down to 14 degrees. My miners were moved to the house as needed. In fact, in January we had windows open in the daytime to release heat. I of course am talking about GPU's, and intend to do the same this year, or move stacks of marto miners.

 Actually my power consumption has never drawn anyone here. But then again, I bought a portable building and had my electric company come out and asked for a second meter. They told me no. As the building is portable, they would never do it unless I gave them 8k to drop the lines. I am considering making a shop in the back yard (20x40 Metal building on a slab) to meet their needs and get it done here. On the other hand, I have 3 other locations I can play with, one of them having 300 amp service, and my elec is only .08 here. One of the lowest prices in the nation.

Nice. Our new shop has 3-phase 200A and not quite that cheap power, gonna be fun to play with.

hoping that sidehack will sell also server PSU so that one time shipping and a trusted Seller ;D

I'll be picking up a batch of PSU on Monday. We're looking into the feasibility of selling a full kit, with the PSU, board, 12x36" cables and a pair of 4-wire fans. Worst case, we'll at least have some PSUs available.

Any idea if these boards will work with the DPS 1600BB PSU? That's the 1800 watt version.

@sidehack

i want to order a full kits with this DPS 2000bb and shpping in philippines how much it will cost?? just 1pc for now i will try the shipment and item

I LIKE THIS FAN, i think this can can cool and look good to DPS 2000bb psu

u got pm sidehack

Anyone who's got these boards willing to sell me one of several?

BTC or paypal.

Please PM me.

Thanks,
Alex.

I have boards with cables in stock, but out on the actual PSU till my shipment comes in later this week.
http://minersource.net/products/delta-dps2000w-with-adapter-board

Any way to just buy the card and cables if he have the PSU already?

Yup- you can select it from the drop down. 2 options, with PSU and without PSU

Awesome!

Just got the board today. Thankfully it's okay but the box looks like it went through hell and back! haha

I will post pics of the box later...trying to locate the battery for my spare laptop right now and will be hopping on the design machine this evening and should have a rough draft ready sometime tonight

See that's hilarious because I actually have PSUs but don't have boards at present. Seems a little backward, but that's the way it goes. As soon as we're done moving, we'll be back to production and should blow through all the remaining preorders and back to standing stock within a few days. Cursed delays! We were supposed to be in a lull right now instead of in the middle of production.

Weird...just clicked the link in my notification email and I get this message...


But when I navigate to the page manually, no warnings, hmmm
Last time that happened on a site I visit regularly, my PCs clock had changed to an earlier date (2008)

Pretty sure that's exactly the IP for this forum.

Yeppers...but why the crap is windows throwing me the warning now? Lemme check a couple other BCT notification links...nope, just clicked the Rockminer notification email link without the warning  :-\

hmmm, very strange, I clicked a link from an outdated (older) notification email for this thread an no warning. Ah well, not long before I start designing the enclosure for these boards!

We got our boards today and just wanted to pop some pics of our setup.  The boards work flawlessly as expected, and everything ended up excellent so far.  Those fans on the PSU are 60mm case fans and seem to be holding up well.  They are only 3-pin fans, but connect to the fan header just fine and so far provide enough airflow as we can tell.

We're doing "blocks" of 4 x S3's per PSU.  If it works out correctly, I believe we can get 4 "blocks" (16 miners) onto a single 30A 240V circuit.  This will give us much more density per rack than maxing out the PSU's with 6 S3's per.

We currently have 2 blocks wired and running stable for about 6 hours so far, will add the second block tomorrow and see what happens.

thanks for posting those pics. They will help with my enclosure development, woot!

Cool, glad it's helpful.  Once I get the other two blocks done tomorrow I might try to take a pic of the rack to show how we have that setup as well.

FYI we used the 18" cables on the top 2 S3's, and the 36" cables on the bottom.  Setting it up like that the 18" cables were _just_ short on the bottom ones, meaning there was now a lot of slack on the 36" cables.  As you can see we did some interesting cable routing to make it presentable and not have cable soup.

Pretty sexy there, sir.

Anyone with a pending order right now, my apologies that it hasn't been shipped out. As has been stated, PCBs were delayed a full nine days past expected delivery, which pushed manufacture back into time we had reserved for a custom job and the full week we were intending to shut down and move to the new shop. We'd hoped to get the rest of pendings out on Tuesday, but the cable parts we expected to have on Saturday just arrived today which meant our stock was basically gone last week and never refilled. We'll be completing the move by the end of Friday and the first order of business Monday morning is to blast out an aslo of DPS2K boards for every pending preorder to be shipped by Tuesday (if the new cable minion can keep the pace). As soon as we're up to stock on those we'll be shifting over to the new D750 batch and hopefully have some of those ready. We will also have two custom jobs to juggle next week but that shouldn't slow us down on pending orders since those take priority.

Just an update. Anything that hasn't shipped out yet should be shipped no later than the 19th. That is much later than originally expected but I can honestly say most of the reasons for it were outside our control. When we got everything we need (like last week) we lay down the law and get stuff done.

nice setup , what fans are you using?

Here's the pic of the box that the loaned DPS2kBB was shipped in...fortunately the board made it safely!

Anyways, I am working on the enclosure and will have a better ss ready soon!

masscool 60mm case fans, 3-pin.

 Looks real good! My question is why the zip ties on the fans, You could use sheet metal screws and washers to barely penetrate the psu case and silicone the edges to insure all air in, is in the psu not all over the place. :) Just a thought...

 If your worried about the screws touching, simply remove them after the silicone is sealed, they ain't going anywhere..

Thanks!

Honestly the zip ties were used for 2 main reasons - first: quick, dirty, cheap (not that screws and washers aren't) and what we have readily on hand (zip ties are never far in an IT shop).  Second we weren't sure about the permanency of those fans, so if we need to move/remove them it's a couple nips from the cutter and they're gone.  We weren't sure if the 60mm fans would provide enough cooling, if they were in the right spot, whether we needed to go up to 3 fans, or go bigger with 80mm (which we did today as a test on a new stack).  Believe me I'd prefer a much more permanent and clean solution, but this is our first proof of concept with this setup so zip ties just made it easier to start.  I could forsee either screws or a custom bracket in our future.

Alright, I am about to print the first prototype base plate...here's the screenshot I promised...
Once I get the base fitment correct I can start making the lid

Can anyone please supply me with the dimensions for the front/rear of the DPS2k PSU?  (just need the width)
Thanks!

I can measure this evening if no one else has by then.

Sweet, thanks! Make sure to measure the bottom please  8)



Also, I could use these measurements for a stronger, more secure mount as i would like to make the mount/enclosure screw onto the PSU...see pic for references. (edit- Distance from screw hole CENTERLINE to bottom of PSU) Thanks!

One last edit...I should have some pics of the base posted this afternoon.
I am printing the 3rd prototype now!

Does someone know the "customs tariff number" / "Zolltarifnummer" for importing the breakout board into EU / Germany?

Rear bottom width - 4 3/8in
Rear top width - 4 1/8in
Front bottom width - 4 3/8in
Front top width - 4 3/8

Bottom to hole center - 1 1/8in
Hole 1/8in note that the hole on the opposite side is 11/16in from the bottom
Bottom of board to bottom of psu - 1/4in

Hope this is helpful.

Very! Thanks much. I will be getting back to work on this today. I've printed 4 prototypes thus far(getting close!)...oh yeah, gonna snap a couple pics and post those asap.

 Would you be interested in building a semi rack for a 2 stack? I will be stacking mine and using 120mm fans. I will need 10 of these. How tall can you print?

 Basically a 2 shelf system with 1 side cutout for the fans.

I could easily make them connect together with zip-ties or screws, or maybe design with a dovetail for adding or removing units with ease.
I'm thinking maybe a 2-PSU design with connectors for stacking more plus provisions for securing the units to a wall/shelving or whatever....they would (possibly) slide over the front and rear of the PSU and secure to the PSU with screws.

About to take pics of what I have so far...nothing spectacular (yet)  :P

Oh and my printer can handle 6x8x6 (xyz) rough build envelope

 Thanks so much for the boards and mainly for all the advice along the way sidehack... My Power is now DONE! Just waiting on fans... and my boards of course.

I wish my power setup was done. We're still cleaning up from the move while trying to get miners installed in the hosting setup and get enough workbench stuff reassembled to start manufacture again on Monday. By the time we're finished and caught up I think I'll have worked around 240 hours in three weeks. Heck of a time for the minion to go on vacation, you know?

Anyone that's placed an order and hasn't gotten shipping notification from me, your boards and cables should be headed your way by Tuesday. We wanted to get them out before the move but cable parts were delayed about four days and the move has taken more effort than expected. We'll be back into manufacturing mode full-throttle Monday morning and should have everything caught up.

 I feel ya man. If I were closer I would pop up and help ya out while ya did my 7 ol' school asic miner upgrades. They still churning making $.42 a day :) Was a helluva run on them. Alas, their days are pretty much done. Wish all my ventures went as well.

 I still have the upgrade I bought from you, and never installed it.. that was like .17 or .27 btc or something like that.

 May have to make a trip up after school starts and I get everyone squared away and upgrade the boards anyway(if you still mess with trivial shit, probably not). I'm in the central AR area which really isn't that far.

I bet coin was quite a bit lower then, wasn't it? I still have my first AM Blade and my first two Cubes, none of which are stock.

Yeah let me know in a few weeks we can plan a guided tour of the shop. Won't be that hard, it's a shop so there's like two rooms.

 Yes, I got my asic miners late oct. early nov. I just knew they would be paper weights by feb. Alas, they still churning. And making money! LOL $15.00 a month! I will soon move them to another loco, and point to alts as I need the 360 watts here now.

 I am in full conversion mode of all my gpus to 240 PSU's. Get ready, I need more boards. :)

 Real quick though.. correct me if I am wrong, but the dell psu cables are the same gauge, and I can simply move them over? I bought extras from you like 3 months ago? They look close.. but a hair smaller. Will they work?

All our cables are 16AWG, and always have been. The spades we changed up a few thousand cables ago, to a product that we found to be both better and cheaper (if you believe such a thing is possible), but the wires have always been the same.

As for boards, we're about to start manufacturing the second half of our standing PCB stock but someone's already spoken for about half the batch. We'll have 40 to 50 boards left of the batch, and as soon as we can we'll be ordering more PCBs (which hopefully won't arrive nine @!#$ing days late this time) but it'd still likely be around four weeks before we'll be shipping again so better place an order soon. The move has really thrown a wrench into administration or we'd probably have the boards on order already.

I just ordered and paid for a PSU from Minersource.net just now so I can model the PSU "rack" design requested.
Afterwards, I will need to sell the PSU...lemme know if anyone is interested. Thanks!


(still in prototype status...sides will be taller, adding the 2x board screw locations, also will have a lid with switch and dial access)

 Count me in for 7 please.

Is there a reseller for this board in Europe ??

I had a guy asking about EU reselling, but I never heard back from him after the initial email.

Do you mean "pjcltd" ?? If so, I sent him a msg and ask. No respond yet.

Do you sell a set with board and cable now ?? In stock ?

thanks
 

I'm interested in bottom cases for these boards. Especially if they make the board sit level with the miner. I'm looking for little rubber feet right now to make them sit level and not contact the metal they are sitting on.

For ours, I just put the static bag it came in underneath the board on top of the miners.  This way it won't contact the metal directly, and it seems to be doing it's job for now.  Those cases look interesting, I might need to try them out.

Not sure I'd recommend that, as the static bag is static-dissipative because it's electrically conductive. Probably a high enough resistance to not cause problems, but the potential is there.

Little rubber feet might be a good thing to look into stocking. Probably gonna get one of those cases too, when they're ready, at least to play with.

+1 on the feet, and the cases as well.

Feet will be incorporated into the design even if I must bust out the Ninjaflex filament and print the feet separate and glue them in place ;)
Printing the 6th prototype now...should be the final version before adding feet and provisions for the lid and raising the sides a bit more.

excuse the crappy pics...it was super late when I took these plus the print quality was crap...doing printer maint. today  :-\

The lid is NOT finished but wanted to give you guys a peek.

Looking good!

Just Need to get a Hand on one of the boards 8)

@sidehack: did you get my PM ??

Anything on the boards shipping today and how long are we looking at?

Every board that has been paid for to date (including yours), which have not yet shipped, will be shipped this afternoon and tracking numbers will be distributed.

Thanks for reply and email also.  :) now Only if you manufactured miners also. ..

I'll admit we did look into that a bit, but honestly there's enough folks already set up to do that we didn't know if we could be comptetetive anytime soon. If Novak builds his lightweight embedded Linux controller though, we might have a start to something. And if ASICMiner makes good on the BE300 having the same pinout as the BE200 that might be worth playing with. But we have a lot of infrastructure to take care of first.

true, bigger game, especially relying on others chips , that can kill everything like the avalon debacle.

We are now completely caught up to all orders, and even the order that was paid for this morning has been shipped.

Unfortunately between a large customer and what we're reserving for hosting customers, there's only 30 boards left of the current batch and it'll be a few weeks before we have more PCBs for another round. So get 'em while the gettin's good.

Additionally, we'll be rocking the D750 boards soon so we'll be able to ship orders by the end of the week.

I'll take 10 more boards, 20 18" and 20 36" cables, if you have them, please.  Paypal like before if that's OK.

Care to spellcheck that?  ;)

kgb, send your request on to sales@gekkoscience and we'll get you fixed up.

Additionally, thanks for catching that spelling hose-up. We're trying our best to be the guy in Bitcoin that *doesn't* screw people over.

E-mail just sent. 

And, so far you've done well by me, your products work exceptionally well and are well built.  I have no problems spending my money with you.  :)

teheehee

Ok.... so Minersource is closing threads. This is not good.

 I guess I need to start selling all I bought from you man, and I would appreciate you allowing me to do here as this whole deal is a major facade...

 BTW Sidehack, why are you listed as a return address for minersource? MO is not that far away as we talked earlier.. but this is looking bad. As in you were in on this. I do not want to believe it but read the facts...

I honestly have no idea what you're talking about. Minersource is closing threads what now? They're not closing anything of mine. Minersource is a good customer of ours and resells a lot of our stuff on their website so we cooperate on stuff sometimes, but there is no direct connection between their business and mine.

I also have no idea why I would be listed as a return address. It's possible you're seeing an address for them in Rolla, MO - which is where I am located. They started out here, but moved to Colorado in January. I knew they were in MO but didn't know they were right here in town until about two days before the move when I handed off the first D750 prototypes to bobsag3.

What's a facade now? Please to explain because apparently I'm missing something.

Okay I think I see some of what you're having problems with, the technobit minion boards stuff. I've got two boards due from that order as well, talked to bobsag yesterday while discussing some PSU orders and whatnot and I was told there were some delays with manufacture. I haven't really been keeping up with the thread for the last 20 pages or so and have no other information about what's going on. Fortunately I am not out of pocket on any mining hardware since last September so I tend to not worry about stuff. I hope you get your order sorted. It looks like they sent your chips to Marto but something got hosed in final-stage communication and I bet Marto is confused about where the extra chips came from. I'm also betting that once everyone calms down and handles the actual issues instead of handling who is to blame for the issues, it'll be resolved pretty quickly.

If you end up bailing on the whole thing and feel the need to resell your boards, I got no problem with that. You bought 'em, you own 'em, you do what you want with 'em. But know that after we sell out of the current batch it'll be probably 4 weeks before we'll have more.

 Man I am confused and pissed. I had it confirmed with Matt and Dan about the conversion of chips, and suddenly this Thomas guy from MS is saying I never confirmed sending chips.

 I am so pissed I cant see straight and yet some asshole name Thomas is saying I never confirmed conversion even when I have a conversion email...
 I spent 1500 with you, over 4k in fans, 500 for electric conversion, 200 in power cords, and countless hours of my time and posters on this board trying to be ready and they are telling me, I never confirmed.

Looks like all that needs to happen is to make sure someone official from MinerSource has your Technobit order number, and then they get that to Marto as an official "this is part of the group buy" and add you to the list. Seems like he already has your chips in hand. Might even already have them converted to boards and just doesn't know where to ship them because your chips are not tied to your order number in the official list.

@sidehack
Just sent you a email with order for 1!

Hope I'm not to late for 1 ?!

Thanks

It's 3AM here. I should have been asleep already but I just finished working about 40 minutes ago. I'll answer in six or seven hours when I go back to work.

Ohh .. Ok! No Problem!

It's 10:00 AM here ... Just had my 4th Coffee :-)
Good night!

I have some pretty interesting ideas for cooling/mounting these, Ill grab some pictures and post them later.

Alright, well if all the current invoices get paid we'll be officially out of stock on DPS2K boards. I guess all you have to do to sell out of something is tell people you're about to sell out and then they all disappear.

We'll be running out another batch of DPS2K as soon as we can; in the meantime we'll be focusing on D750 stuff and fresh boards will start shipping on Friday.

I will be posting updates on the enclosures tomorrow...I've been juggling a few design jobs and will be getting back on this project first thing in the morning. If all goes well I should have the pre-production case ready by tomorrow evening.

I recieved my breakout board yesterday.  Just wanted to share the board and psu setup so far

I recieved my breakout boards today and cables, looks great! great seller!

Printing the latest revision now (well the base) and will print the lid in the morning...plus my PSU should arrive tomorrow so I can work on the PSU stacker-mount and make any final changes needed to the breakout board cases before giving the green light for production.


Quick question...what is the dial/potentiometer on the board for?
Is it used much?
Would there be a need to adjust the dial/pot without removing the lid?

Thanks!


Any special requests for these cases?

The potentio meter is for the speed adjustment of the fans.
ill keep that one in reach if possible

Awesome and thanks for the reply mate.

Just gotta take pics of the latest print...had some unforeseen circumstances crop up this morning and I was able to get the lid print started a mere 3 hours after I went to bed earlier. Cleaning up my photo studio area and taking pics asap. Once UPS delivers my PSU I can  start working on the feet and screw mount locations plus the 2x PSU stacking rack, which I should be able to make modular so you can add more 2x PSU rack units without tools and keep them secure.





Thanks for this pic (and the other)! Very helpful/insightful for my enclosure design. Time to modify the lid so that connector can be plugged into the board without removing the lid.



edit: ZOMG! My PSU just arrived and I attached the encased bb...NO FEET REQUIRED! Plus it won't take long to get the screw holes added. I've already adjusted the lid design to allow the cable/connector to feed through the lid (optional).

Taking pics now!

PICS!

Making necc. changes to the model now to incorporate PSU mounting screw locations, should have more updates in a few hours.

Edit:Now printing the recent changes. I will post back here with fresh pics and more info on the case in a couple hours.

I am already scheming ideas for the 2x PSU modular stackable rack, woohoo!

ps- thanks data55 for loaning me the bb  ;D

Look very good! What kind of fan's are you using? Are those loud?
Like to set up my PSU alike.

Thanks

i used these fans:
http://www.ebay.nl/itm/390571240790?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

they move a LOT of air on full speed (more than normal 80mm fans), but can be loud. Before i placed the fands i i removed the mesh of the psu cover behind the fans to get an better airflow (hole of 38mm) then i screwed the fans from the inside.

I hate to bring this to you, but that lid aint gonna work if you use proper wiring:
http://s30.postimg.org/dmg7gp9kh/20140823_135144.jpg

Meh, simple fix mate!  ;)

Printing the latest lid revision now. I've added more clearance for the cables. Pics WITH cables installed soon!

Here ya go mate...all fixed up  ;)
Ye ask and ye shall receive!

Just don't try to plug any hardware up with your cables attached like that.

Pretty nifty setup overall.

Word and yeah,I don't have access to 220v so I can't use it anyways  8)
Just glad I was able to borrow a board and had the $$ to purchase a PSU for product dev.
Going to start on the stacking PSU racks,which will be modular so you can add more PSU's on a single "rack"

Order info can be found here...
https://bitcointalk.org/index.php?topic=694666.0

Thanks all!


edit: I will be making a trip to the local hardware store with a PSU and case bottom in hand so I can source the proper sized bolts/screws for securing the breakout board case bottoms to the PSU..I thought I had some here but there were either too small or too big, hehe

what kind of fans are you guys using ?

i put 2 40mm fans on the side, but they are just normal papst ones, not server grade.

and the psu shuts down when im pulling about 2kwatt, i can feel it getting realy warm, so im assuming the heat is shutting it down.


any tips and links to fans that are being used and works with 2k watt draw would be much apreciated :)

The fans im using displace almost 24 CFM and they are server grade

I'm using 60mm case fans, server grade with 20+ CFM.  However, with only 2 of them the PSU's still get quite hot although they seem to run fine (powering 4 antminers).

Anyone successfully running 3 fans against the PSU?  I'd like to add a third but the Y-splitters I got don't seem to work with the pinouts on the board.  Is it possible to instead just run the fan wires right off the breakout board screw terminals?  Or is that too much voltage that'll fry the fans?

ordered myself some of these : http://www.ebay.com/itm/IBM-x3250-Server-Fan-Delta-TFB0412EHN-4K29-/360870345147?pt=UK_Computing_Case_Fans&hash=item54058c79bb

should do the trick i would think

Couldn't tell the CFM from the listing.  As long as you're north of minimum 15CFM, 20+ would be better, two of them should work.  Three would be ideal and cover all the spots you need to cover.

Ive gone for these http://www.overclockers.co.uk/showproduct.php?prodid=FG-038-SV&groupid=701&catid=2331&subcat=819

2 for each psu, should be ok.

Running fans straight off the screw terminals is fine so long as they're standard 12V fans.

Our test setup used a pair of high-CFM 80mm fans and kept the supply comfortable at 2500W output.

26CFM

Those'll work fine.  I think my masscool"s are about 20.

So, an update on my fan setup (without pics, maybe tomorrow).  I was able to get 3 x 60mm fans tied together and then zip tied to the side of the PSU, and have them powered directly by the breakout board terminal screws (I don't care about fan speed, I want them running at full speed, screw the noise).  I have them so the airflow is facing outward, meaning the outside air is sucked through the PSU, instead of trying to push the air through it.  Seems to work very well so far, the PSU is noticeably cooler than previously with either 2 x 80mm or 2 x 60mm fans.

Would'nt it be bether/more efficient to place the fan's ON TOP of the PSU ??
Of course, one would have to cut some holes into the metal cover ....

But I think for cooling it would be more efficient.

http://abload.de/thumb/imagesnv7qbxecpsk96.jpg (http://abload.de/image.php?img=imagesnv7qbxecpsk96.jpg)

You could try.

I also thought about that option but the heatsinks are positioned for airflow from the side.

Those would fit perfect since the case of the PSU is 105mm: http://www.ebay.de/itm/Arctic-Cooling-Arctic-F9-92mm-PC-Computer-Gehauselufter-1800rpm-43cfm-/360945537772?pt=DE_Computing_Geh%C3%A4usel%C3%BCfter&hash=item540a07d2ec

Does the 3 Pin connector work with the board ?

yes that will work

So, will this work with a DPS-1600BB?  Pinouts look the same, and since I'm running only 4 Ants per PSU I'd be fine within the wattage requirements.

 just got the boards a couple of days ago and had 4 psu's waiting which I got of ebay now 2 of the psu popped yesterday don't know why the boats are ok as use the remaining psu and seems to be running ok I have 2 of the following fans on each psu http://www.overclockers.co.uk/showproduct.php?prodid=FG-038-SV&groupid=701&catid=2331&subcat=819

had 6 ants on each psu , what could be the problem?

Probably not enough CFM. These PSUs can be really heat touchy.

I had three identical setups of 5x AM Tubes across 2x DPS2K. On each I put a lightweight 120mm fan (12V 0.5A 3-wire) and a sturdy 120mm fan (12V 3.3A 4-wire) to keep them cool. Two of the setups are running fine on probably around 60% speed on the sturdy fan. The third setup, one PSU kept cutting out even with two sturdy fans at 100% so I junked it and swapped in a fresh PSU, which has been performing beautifully.

Used equipment has varying tolerances on what it can handle, I guess.

yes used equipment is used equipment but 2 in a matter of days I thought I might be doing something wrong, they do get hot I think it must be the fans they are just not up to the job,  I didnt know the board comes with the pwm fan pins. The fans I used seemed slow to me I will have to change them I reckon even though it said a minimum of 25cfm on their description but for 3quid what should I expect.

I had one PSU keep popping off , and I only run 4 Ants on any of them.  Felt really hot - it was cooled at the time with 2x80mm fans.  Swapped those out for 3x60mm fans, configured to pull air out, instead of trying to force air through.  Been running like a rock ever since.

I've had extremely good luck with the 3x60mm fans configuration, and would recommend you try that.  If you want to render your fans useless later on, you can clip the connector end off of it and put the wires directly onto the breakout board terminals (as long as fans are 12v), instead of worrying about the headers off the board.  I can snap pics tomorrow if you want.

ok , i had the fans blowing in towards the psu. ive been looking at he 60mm there are some high speed ones at 4500rpm, im going to give it a go i think and do your suction technique, i snipped the current fans also as 2 wouldnt fit in the pwm pins.

on what side of the psu did you put the fans to pull out ?

ill soon be recieving my high cfm 40mm fans and would like to try the air pull method

If you are looking at the PSU with breakout board to your chest, the right side.

I'll snap a pic or two today.

here is my setup (top psu still missing 4 antminers on the way)

5 antminer running OC 250 seem to be drawing about 2050watt from the wall.

also the fans im using, on pull instead of push worked miracles, i run them at half speed and the psu is not warm to the touch anymore.
the type i used is a few posts back.

ty for the fan tips kgb2mining

Ninetoe - those look really good!  And you're welcome, I'm happy it's working the same way for someone else... you never know when you make a suggestion if it's gonna work for someone or if it fails and you look like an idiot... :)

I promised pics of mine with the new fan setup, so see below.  I am also going to make a second post about the breakout board holder, as I got my shipment in and have a few comments.

I'll also confirm power draw.  With my "cube" setup of 4 Ants per PSU, I am able to get 4 cubes per 30A 240v circuit to run reliably and cool.  This allows me to get max density of 32 Ants per standard 19" rack cabinet, with only 2 circuits per cabinet.  And, the S1's are overclocked to 393/400 as well so it's still able to hold just fine.

Here's a finished "cube" with the fans on the right side, set to pull air through:

are you overclocking your antminers ?

maybe im pushing the PSU too hard running it at 2000watt constantly.

The S1's are overclocked to 393/400.  But still I'm only running 4 per PSU so at most I'm pushing 1600watt, most likely closer to 1500.

Just a quick peek at what I am working on for these PSU modular "racks"

http://i1141.photobucket.com/albums/n596/MZStrongbow/Mining/DPS2kBBrackss_zpsf2818416.png (http://s1141.photobucket.com/user/MZStrongbow/media/Mining/DPS2kBBrackss_zpsf2818416.png.html)

Shipped a batch of DPS2kBB PSU breakout board bases to MinerSource.net just yesterday!

I will be test printing  these racks asap. Stay tuned

Partly because of a multi-point failure of finances (deposit computer errors and slow/non-paying customers) we were delayed about two weeks on ordering materials for the next batch of DPS2K boards. The next round should be available starting in about 4 weeks. We'll open up a (pre)order queue probably sometime next week once we have a better idea of when we'll be shipping.

Nice bro!

Shoot me your shipping info, I will toss a case or two in the mail asap.

RE: cooling the PSUs

I just use a $20 3 speed 8" A/C fan per 2 PSU, never had a cooling issue.
The fans were on middle setting for >90F ambient summer cooling.
Recently down to 'low' super quiet. :)

I follow the school of thought that pushing is preferred to pulling air for cooling.
Compressed air can carry more heat away. (in theory)
I also prefer lower tone of fans pushing.

One must inspect and in some cases clean the insides of dirt.
Some are pretty clean and some have gunk in there...


RE: DPS-1600 and DPS-1800 W PSUs
I can confirm the 1800 and 2000 work equally.
I'd expect the 1600 to also work.

I wouldn't mix different watt PSU on a 'combined' 12VDC rail though.


YMMV
:)

Novak and I are working on a design for a control board that'll interface to six or eight of our PSU boards at a time (both the D750 and DPS2K boards, plus whatever we release in the future since they should all have a standard header) for monitoring and control. The current plan is to make the board-end giblets connect to the control base with ethernet cable, so you can spread things out however you want with what lengths of standard cable are available; the control base would tie to a computer through USB. We'll probably write some basic linux command-line software for monitoring and control, possibly with a basic webpage port for displaying status. If everything works how it should, it's a thing that should run off a Pi without trouble. Still in design phase, but more people expressing interest will probably speed that up. We figure on deploying some at least within our own hosting setup to test and mess with, should make it easy to power-cycle miners remotely as well as monitor PSU status and such.

The dip switch on the board, does it have to be on a specific setting

Switch 1 enables internal fan control
Switch 2 enables external fan control
Switch 3 enables external-on function

ok but what should be on and what should be of? ?

That depends on you. We typically ship them out with internal fan and external-on enabled. If you don't want to be able to turn it on from an external signal, kill EON. If you want to control the fan speed from an external source instead of the built-in knob, turn that on.

internal fan control will control the pwm fan based on the temp in the psu ?

No. Internal fan will control the PWM fan based on the knob on the board. If you want temp control, you set up a temp measurement and pipe it through the external fan control.

ok thanks

Sidehack is there a 5v out on this board? I am looking to use one to replace my current cointerra machines. the 5v feeds the beaglebone.

Yeah there's two pins on the header labeled 5VO which can source 5VDC up to 2A without any trouble.

 Mind showing me where? Don't see em

 Meaning I have 2 connector. I understand the output. Do I need to split the connection, and where would I get ground from?

The ten-pin header at the corner of the board. I don't have one in front of me, but it's identical to the header on our D750 boards; in fact, any questions about the operation of the board not specific to attaching fans to the 4-pin headers can probably be answered by reviewing the D750 V0.5 spec doc on the product page on our website.

On the header is a ground pin and two 5VDC pins, all labeled. The 5VDC is available any time the 12V of the PSU is outputting.

 I saw it on the spec doc. BTW the link to your 2000w on the homepage is bad, you have it pointed to the local ip instead of gekkoscience.com

 Can you tell me how I would wire a 3 pin fan instead of a 4 pin?

 Thanks in advance!

I'll talk to Novak, he does most of the webpage stuff.

To wire a 3-pin fan, stick it in the 3 pins closest to the small capacitor. You won't have speed control so it'll be at 100% all the time.

 Yellow or Black closest to the capacitor?

Black. Just like plugging in a 4-wire, except the blue wire doesn't exist so its pin stays empty. Same as every other plugging a 3-wire fan into a 4-wire header.

Anyone looking for a good PSU, I've got one laying around and I will be posting up for sale asap! Only used it for product development and I've no access to 220v nor any plans to in the future. PM me for info.
Thanks!  8)

On that note, we're taking inventory and gonna be sending off for the rest of parts for a batch of DPS2K boards this week. We're probably going to open up an official (pre)order queue about Wednesday, with shipping expected to start on or before October 10th (unless the PCB folks decide to ship us a week late again, grumble grumble). We'll have some PSUs available, and probably the option for a "kit" with PSU, board, and 12x 36" cables in a box with flat price including domestic shipping.

 Are you doing full combos now? or just the board. I need a few more setups.

 Also, would you be interested in a dell 750 trade in? I have 6 of these and the boards I am phasing out. Let me know!

I need a Dell 750 and board combo for product dev. if you'd be interested in trading for my DPS2kBB PSU?

We don't really have any stock of any thing except 36" cables right now. Also not terribly interested in a trade-in, but I have no complaints if you want to resell anywhere and undercut us. We won't have D750 stock for a while.

As for any "full combo" option, what was said is what we're thinking. I don't have a lot of available PSUs, couple dozen maybe after hosting customers get theirs, but we'll do something.

Please let us know as soon as you get new boards in stock, or if you will open a pre-order list. I need two boards w/cables.

I can send you what you need, I recently upgraded from the 750's, so I have a ton of PSU's and boards sitting on a shelf.  If you want to send me a pre-paid shipping label for USPS, UPS, or fedex I can have it out in the mail tomorrow.

Word! Did you want/need this DPS2kBB PSU I've got here? I will dig up your info and have a label sent your way asap, gotta run a couple errands soon. Thanks bro!

If you want to do a straight trade, that'd be fine.  Just PM me your shipping address and I'll pay this way, you pay the return shipping of the dps2k... good?

Deal! You rock, PMing you now and I will get this PSU out today/tomorrow as well, it's already boxed up.

yea awesome dick move me man! You rock.....3d printer shipped.

I'm going to officially announce the start of the Round 2 (pre)Order for the DPS2K boards. PCBs are on order, we got a full inventory of all current parts stock and expect delivery of the remaining parts early next week. PCBs should be delivered on or before October 3, which giving us some buffer time to create stock (and for the board house to screw up and ship late again), we should start moving boards on or before October 10th.

Pricing is the same as last time.

We will have a limited number of PSU Kits available (probably about two dozen), packaging a DPS-2000BB PSU, one DPS2K interface board, and twelve 36" cables for $154. That may not sound like a great deal when you add everything up, but that's the shipped price so it actually saves you $15.

We kinda got shafted on the last few rounds with people requesting large orders and then taking their sweet time paying (never knew a guy to take two consecutive vacations with exactly enough time inbetween to respond to emails but not log into PayPal...) so we're making some rules. If you ask for something, you have exactly three days from invoice issue to pay for it or the order is cancelled and you lose your spot in line. When we start shipping from standing stock, no matter how much business we've done in the past, nothing will be shipped until the order is paid in full. The official queue will be assembled in the order that payments were received. The only reason we're not shipping from standing stock right now instead of in three weeks is because we didn't enforce those rules on the last batch of shipments and some people took advantage of that. We will not make that mistake again, as it hurts us and every other customer entirely too much.

Additionally, a note to any overseas customers. If you're in a place I have a reseller covering, I will redirect you to that reseller and that reseller sets his own price as necessary to cover his own expenses. If you're not covered by an existing international reseller, I can ship to you but know that I do not falsify customs forms for any reason ever. The listed contents will be accurate, the pricing will be accurate and it will not be labeled as a gift.

So, if any potential customers could direct themselves to sales@gekkoscience.com, and I'll only respond to messages with ALL OF THE FOLLOWING INFORMATION:

1. Exactly what you want (how many kits, how many boards, how many cables of what length - please be specific)
2. Exactly how you would like to pay (if BTC, say so; if PayPal, say so and also provide your PP address for invoicing)
3. Exactly where it needs to be shipped (any details USPS will need to know to get it there the first time)
4. Your forum handle (optional, if you want to be recognized on the public order queue)

 Can I get on the list for 4 more boards please, with 32 36 inch cables please. I just ordered the PSU's.

Sidehack, love you work but I have a request.  Is it possible to get just a very stripped down version made?  Something that just plugs into the PSU and provides connectors to PCI cables (or is just hardwired to a bunch of PCI cables would be better).

It is great that you can add a bunch of features, but I think those features add to the cost and it is all about getting the cost down.  All the things like external fan control, current sense output, 3.3VSB, 5V2A, POK, external turn-on, and current-share for load balancing would never be used by me.  Just something that can go from the PSU on one end and PCI out on the other would be the most perfect to me.

Overall, I love your work but I am curious how low the price can get.  When it is still $50 even when buying 100, I feel there should be a "no frills" model.

Thank you very much!

The bulk of the cost is in the heavy parts, really. The PCB is a four-layer board with 14oz copper in the main traces (should be good for 240A), and even in the quantities we buy, the PSU connector and screw terminals aren't cheap. Add the labor cost of assembling and testing each one, and the "we like being able to pay the bills" necessary markup and there's not a lot left. Knocking off the fan speed and 5VDC circuits saves about $4 in parts and labor. 3V3, POK and EON collectively might drop another $1.50 or so. Depending on how many you're wanting, we could work out a custom-populated batch or, for orders large enough and with enough lead time, a completely custom design.

Also, I'm deliberately not responding to order requests in this thread because, well, RTFP.

I was figuring that the PSU connector -> PCB would get the cost to less than $4,450 for 100 (you said there can be about $4 and $1.50 in savings each).  Looks like I am wrong.

I have followed this since you released the ones for the dell 2950 PSUs.  I always thought, maybe if he used some of the larger IBM PSUs it would be more cost effective due to the scale of the larger supplies.  Then you buillt one for those as well.  I was happily surprised, but still never able get the price to where I could order a bunch.  Just seeing if there is a way to make it work.  Thanks for your input. 

I'm not sure where you get these assembled and what the manual labor costs there are, but have you looked into a cut down version without the screw terminals and only the PSU connector and a cheap on switch and just directly soldering 12 36" PCIe cables to the board?

We do all the assembly in house (with real Americans; we will never for any reason outsource anything to foreign countries). We also don't really like the idea of not-flexible options, so soldering a fixed number of fixed-length cables to the board doesn't go over so well. If we knew we were going to be able to sell a couple hundred we might go for it, but since batches of anything aren't per-unit cost-effective until you start making at least 250 and the capital cost for 250 of anything is a five-digit number, we aren't going to jump into something we don't like and hope it's not a huge waste of money. If someone came in and wanted at least a hundred, and paid down on the order, we'd do it.

dance191, how many would you be looking to fetch if the price was right? Nothing wrong with discussing some options.

PM or email, let's go over some numbers and see what comes out.

Cool, will do now

hello thier, i set up my DPS-2000B and works for 40 seconds and it shuts down it get's very very hot? can hardly touch it what can be wrong?

Did you put any fans on it?

PCBs just arrived, a couple days early instead of a solid week late. That's pretty great. Looks like we'll be shipping early this time instead of the other thing.

 You taking preorders now?

I surely am. Opened up the queue last week when we had solid dates on all parts availability.

Great to hear Sidehack! Just in time for some prisma's soon.  :) Keep up the good work, these are great boards.

Sent an order 5 days ago, but haven't heard back. Invoices and order confirmations are sent when the product are ready for shipment?

Btw: Got two of mstrongbow's 3d printed cases in the mail the other they, and they have a really good fit to the PSU. Looking forward to mount some boards in them

Unless you're the guy from Norway, then I didn't receive any order emails from you that weren't replied to.

 Need 4 more please, unless there is a discount for 5.

Yes, I am the guy from Norway. I double checked now, I sent everything needed.

I held off on replying because we were talking with a guy about doing EU resale, but then I haven't gotten back to him yet. I'll field your order, expect an email shortly.

please update the 1st post for updated price ..

No.

Looks like the first orders will be going out tomorrow (Tuesday). I like it when materials arrive early, instead of super late (like last time). We're officially shipping from stock.

any News on EU reseller?

I have one board for sell but only WITH DPS-2000 PS togheter. Schipping from DE or CH. Whatever is cheaper ;-)

No, I still haven't gotten ahold of the interested EU guy. Been too busy making stuff.

All "preorders" have been shipped as of today and we are now in standing stock. Any order paid up will be shipped immediately. We've got stock on PSUs and both lengths of cable.

Hey Sidehack, shoot me a PM with your shipping address, I'd like to send you a case or two.

Also, any chance you could add a 5v Type A female USB header on any of your boards?
This would be a great feature allowing to power 5v devices such as R-Pi, BeagleBone and WRT router/AP's etc.

I really wish I had access to 220v as I would definitely utilize some of your products.


Thanks!

Any kind of USB made to be wired to a motherboard header will work, as the 5V and GND are spaced right. I have a RPi running off one in our hosting facility wired up just like that. I know the bitcoin economy is shifting away from the kind of people that don't always enjoy (or know how) doing most things for themselves and plug-and-go stuff is getting a lot bigger so catering to plug-and-go kind of people will probably be more of a thing than it was.
We could probably add one, if there was enough demand. It would require adding that part to the BOM and a bit of redesign to the PCB, but if we get enough people asking about it, maybe. So far I think you're the first.

Oh yeah, and we've had several people asking lately, as though it were a difficult favor, if they could buy cables without buying a board. Anything we have for sale, we'll sell. Doesn't matter. You want cables, we can sell cables.

I've got about a dozen 80mm 4-wire fans that work well in pairs for single PSUs. The leads would have to be stretched/spliced to reach the boards properly but that's not hard.
I also have some 12-foot NEMA L6-20P power cords for these PSUs.

While supplies last, I'll toss in free fans and power cords upon request for orders over $100.


Also, we're working on a deal that might allow us to drop our 6-pin cable costs and also increase flexibility in custom lengths and configurations. That's good news for sure.

All orders placed between noon Tuesday and end of Sunday (10/26) can get a special discount pricing. All DPS-2000BB interface boards are $45 in any quantity; 18" cables are $2.75 and 36" cables are $3.75 apiece in any quantity.

Can I stray a bit off topic and ask the question: What's the back story of these surplus power supplies? They seem to have made a lot of them. Did they actually go in server computers? I was thinking maybe they used them for powering wireless telecommunications? That would explain the trainloads. Does anyone have any of these power supplies that came with a history?

This particular PSU was used in IBM BladeCenters. I think each 6U machine had 4 PSU in it. Not sure if they had any other purposes from the start.

Thanks Sidehack! A quick wiki search yielded this juicy picture:

(They look a lot more shiny and new than mine LOL)

http://upload.wikimedia.org/wikipedia/commons/1/19/Bladecenter-back.jpg

FYI, as far as as I can tell from looking at the pin outs, the DPS-1600BB (147.5A @ 12.2V 1800W), DPS-2000BB (164A @ 12.2V 2000W), and the DPS-2500BB (205A @ 12.2V 2500W) are pin compatible and the DPS2K adapter board and should be a "Plug 'N' Play" on these supply's.

Just ordered qty 16 DPS-1600BB's and when they come in will test and report back.
We scarfed these in the salvage market for $8.74 each + $10 shipping.
Total cost each was $18.74. Helluva' supply for $20.

These supply's have NO internal fans and in a stock configuration (i.e. installed in an IBM BladeCenter) are cooled by case air.
Adding 40mm fans to the side of the power supply case for cooling is MANDATORY.

We anticipate using these in our mining farm to power OC'ed AM Prisma's.
One supply per Prisma.

Of other interest is, the efficiency of these supplies under light loading (250W draw) is 87%, at or near rated output the efficiency rises to 92%.
So from a Bitcoin mining perspective it's better to run them WOT (Wide Open Throttle) than to be conservative.

Individuals in the RC community have reported about the DPS-2000BB's that when tweaking the output voltage to 14.6 and tweaking the Over Power Cutoff the DPS-2000's can supply 2800W (~200A @ 14.6V), Booyah!

Our boards were designed for a 240A rating, and the first one was stress-tested to 200A for a full seven days with zero problems. It was actually a current-sense board, so the PCB had to deal with the extra heat of 200A shunts and still performed beautifully; stock boards will do even better. They should be alright for a DPS-2500BB.

The only thing about adjusting the DPS-2000BB settings is, over-current is an internal pot so you might have to take the case apart - which is actually very easy. Overcurrent protection usually kicks in just shy of 200A but can be adjusted up over 210A I think.
Output voltage adjustment is not implemented on our boards, partly for safety reasons. We didn't want someone grabbing the wrong knob and roasting all their hardware accidentally.

sidehack,

Is the price still "reduced" -- or does the thread title / OP just need to be updated?   (I saw conflicting info -- one post said through the end of October, another suggested the sale would last until the Prisma group buy had concluded...  Etc.)

If things are still on sale, could you maybe...say what the prices are, because the original prices, the dropped price, the discount amounts, and the recent sale -- it just...um...seems kind of scattered about all over the place and it's  kind of hard (for me at least) to figure out what the actual *price* is.

I realize I should be capable of locating this information -- but I formally admit defeat and would kindly request a current price list, just whenever you get the time...not a rush or anything.  Thanks!

Yeah I guess the title needs to be updated.

In any case, the prices in the first post are the current prices. We had a housecleaning sale a few weeks ago and dropped all prices, but that has ended.
We're still offering a 10% discount to anyone purchasing to power hardware from Canary or CrazyGuy Prisma GBs though, just gotta let us know that's what you're doing. There's no particular reason, just we like those guys.

Novak and I were discussing pricing the other day though, so I'll talk to him and see if we're gonna make any changes. As of right now, what it is is what it is.

if someone in Europe is interested in single quantity boards,
im willing to sell 3-4 of mine atm for the price i bought them
the postage should be like 6€ for a letter or 10€ for a parcel

Also, we have reduced prices. Price breaks are now $55, $52, $50, $48 for the quantities listed.

Pretty soon we'll be able to offer more or customizable cable options as well.

We're still selling from standing stock. All boards and cable lengths are available. We're also able to do custom-option cables (wire lengths, spade/strip terminations) with a couple days' lead time.



Additionally, some news. How much interest is there in DPS-800GBA and DPS-1200FBA PSU interface boards? We've got a working prototype for a single board that works with either PSU, but we need to be sure there's enough interest to merit building it. Expected per-board retail probably around $35 plus shipping. We'll probably be adding a 5VDC line to it, with a USB plug for powering Pis and such, but that feature might not be in the base price (probably add about $3 for parts and labor).

So, I've put up a consolidated post with all of our offerings in the Marketplace/Computer Hardware section. I'll be maintaining that as the official purchasing thread, I reckon, with updated prices and information.

https://bitcointalk.org/index.php?topic=940317

Boys and girls,

I know this looks like a reaaaalllly old thread, but in case anyone's interested ..

I didn't really like the approach of how the breakout board is doing it, nor did I like the back-order mentality.  With that in mind, I went ahead and designed my own PCBs, which I believe offer a better approach.  Validating the prototypes now and results look good.  Expect product to be in stock and ready in the next two weeks.

Once ready, I will post a link to where my boards can be ordered from and a price.

Thanks,

the prof.hell

Yep, this is a really old thread. It was replaced almost a year ago and left to the archives. I'm also not sure what you mean by back-order mentality, but it sounds like something I don't like either.

Being as I've been out of stock on these boards for a while due in part to cost and in part to limited demand, go right ahead. But when you announce your product, please do so in your own thread.

sidehack, i do not know what you and novak are going to do...

prof.hell, is in town, and that is 2 L's in hell

I know I cannot wait to see what product comes with my very own prof.hell wrapper. ::)

Yeah I really don't know what most of that means. On the breakout board front, Novak's working on a new edge-connector board but prototypes for that won't be ready to show off until about the same time I have pods to show off (probably around two weeks).

I wonder what mister proff's up to.

Any chance you have one more of the DPS2000 boards left?

Thanks

https://www.youtube.com/watch?v=VuKnRDt8x0w

Um, thanks?

The only thing I liked in that video when the guy turned two supplies on and the fans drown him out.
He had trouble showing off some  of the fan controls what you see in this video has to be in top ten videos not to sell your product
