Edit, the board design changed from 16 to 22 PCI-E connectors to allow it to maxmize the use with ant S5 units. 5.5 ant S5 will draw 5.5*500w=2750w from the PSU

The idea behind this breakout board is to cut down the Power Distribution Units cost for larger farms with a high efficiency PSU that's 1.5 to 2 times more powerful than the often used Common Slot and DPS 2000 BB PSUs.
Another advantage of the Bladecenter H PSU is that it does already have the fans, unlike the DPS 2000 that could be time consuming to setup for large deployment.

Not to forget, the Bladecenter H PSUs are 80+ Platinum certified, 94% efficiency.

After making a small batch as a proof of concept, I'm wondering if there would be enough interest in these to make a bigger batch.
The main connector does have a 140pcs MOQ with 6 weeks delay.

Technical data:
IEC C20 input Plug
22x 6 pins PCI-E connectors rated 9A per pin (27A max per 6 pins cable) to allow up to 5.5 ant S5 on each PSU
PCB with 4 layers of 2 Oz copper.

Pricing excluding shipping for each board will be as follow:
1-25 boards total ordered -> 70$
26-50 boards total ordered -> 65$
51-100 boards total ordered -> 60$
over 100 boards total ordered -> 55$

Since there was a little more interest that I expected, this first batch with flat price will close at 200 Pcs or on the 11th january 2015 whatever comes first.
Orders made past this limit will only be processed the first week of february, and the flat rate pricing of 55$ a board won't apply anymore. You will pay a price based on the quantity you will individually order as I'm already offering on the other boards.

Pricing for 16 AWG cables with plug at both ends will be as follow:
My home made cables are using 1.5mm² copper wires.
according to tables, 16AWG is 1.31mm², 15AWG is 1.65mm²

Price for those will be
2.5$ for 24"/60cm
4.0$ for 36"/90cm

I can also source cables with 16AWG aluminium wires, the price should be 0.6-0.8$ cheaper than the copper ones.

For those of you who'd want to make the cables or add a connector to existing cables, I'm also able to provide the crimp pins and 6 pins connectors at a fair price:
0.20$ the 6 pins connector, and 0.04$ the crimp pin

Boards for small orders will be delivered as one batch in the US and stocked by a reseller to be dispatched to end users at lower shipping cost.

If a few boards are needed before I get the connectors from the manufacturer, I can have a few as I did for the first prototypes, but individual price for the boards will be close to 80$.


Here are some pics of the actual board and of the first order before it's shipped.

Really nice man

I'm not sure I understand what the C20 is doing there?

That PSU does not have the conventional C## input plug, only a proprietary IBM connector.

Exactly, you were faster than me.

here is a pic of the 3 pins proprietary connector

https://i.imgur.com/eDJjsT3s.jpg?1 (http://imgur.com/eDJjsT3)

I would be interested for sure but 6 weeks is too far out.  :( Sending PM

Oh interesting design. I think as a few others have said, it will be hard to justify a 6 week lead time as people either need PSUs now or they don't need PSUs. Will also have to find a reliable and bountiful source of the PSUs themselves.

Ps, can you create a tiny plastic cover for the interface pins that are visible on the front side? Then that front side has no touchable live surfaces.

you got reply.

Unfortunately, many FCI connectors aren't stocked anywhere and seems to be manufactured on request.
That's why I need some time to get them.

Your request on the pins cover is legit, I'll have a look at something easy to do.
Worst case will be to cover them with some non conductive rubber.

What I was really saying is this might be something you'll have to put down for in advance, and sell as they're in stock or a few weeks out. If you can cover those pins then its a significant USP over the DPS2000-BB which has exposed stuff everywhere without a case, and has downward facing pins which get very close to whatever shelving you use. Those that use metallic shelving or even treated wood have to be careful and usually sit it on something.

Only the first batch will need the 6 weeks delay since the connectors will then be ordered in advance. The other ones will be either in stock or short delay
I have a first batch of connector already ordered, but once I'll reach 75 reserved boards from this first batch, I'll order a second batch of 140 connectors.
And you are right, the DPS 2000 does have a few bad points, that's why I looked at something else with some nice power.

First post updated with the "reserved" quantities.

Since the first steps in pricing are reached, worst case will be 60$ a board + shipping.

PM'ed back, finally. :)

Hi!

in a few days my  Astec AA23920L should arrive ... as I want to connect a BIG cable directly to the PSU, I am asking if its possible only to buy the Connector for 230V and the 12V ?

Do you have any internal information about that PSU such as pinouts ? Would be great if this PSU can deliver higher voltages (such as 14V) ... do you have any schematics?

I really appreciate your answer!

Best regards,
Martin

Hi, I assume you will use it for RC chargers or something similar, since you want to raise the voltage.
Unfortunately, I won't have any spare 12v connector until my order for the 140 ones will be delivered, end of january.
The 220v one is easier to find, and not that expensive.
I even have some already wired to an EU plug from my first tests.

As for internal schematics, this PSU is quite undocumented. "external" pinout is available, but nothing else.
I'm not sure if they explained how to, but I've read somewhere that people were able to raise the voltage, I'll have a look if I can retrieve the data.

If you are interested in the 220v connector wired to EU plug (or with bare wire for you to put the plug you want), just send me a private message.

Very nice looking! I am interested in one, possibly 2, of these boards. My setup is long overdue for a cleanup, and these will provide just the reason. Looking forward to updates and solid pricing.

Pricing will be 55$, I have over 100 reserved.
If you are in the US, I'm currently discussing with someone who will stock them to allow cheaper shipping on low quantity.

Hi!

Yes if you can find this out for me, that would be great!

The connectors make only sense if using both together. If i have to solder the 12V connectors, i can solder the 220V connector as well ... ;)

For the usage, I will use that PSU to power / "buffer" my car hifi equipment while being on a contest.

Thanks in advance!

Best regards,
Martin

I'm looking to get a few extra connectors like the 20 first ones I've got for prototyping, but they aren't common, and they will cost around 20€ a piece. Currently waiting for a reply.

J4bberwock,

put me down for 1 as well..

You've been added to the list.

For now, I'm still waiting for 250 connectors from FCI.
To speed up delivery, I'm also looking to get second hand power midplanes/backplanes for the bladecenger H, but they are hard to get for cheap in Europe as I already bought all the "not too expensive" ones to build the 20 first boards.
I'm waiting for an answer from a broker that may have enough boards for 40-100 connectors.
I'm also trying to get some alternate references from FCI that will need some trimming of extra pins to fit the PSU.
If one of the alternate options works, that will allow me to deliver mid january for a first batch of boards.

Count me in as well for 1 board. I would need cables too.

is this board and its components, strong enough for 300w per 6pin connector?

I just got 50 of these bad boys in today.  Look how much bigger they are than the DPS-2000BB!

https://i.imgur.com/zW1REZz.jpg

Hey smracer,

Could you do me a favor and give me measurements of the IBM Blade center please.


Thanks

44cmx20cmx6cm
17.32"x7.87"x2.36"
The breakout board without the cables will add 2.5cm/1" to the total length

I'd be interested in picking one of these up. Can you add me to the list? I'm located in the US if it matters.

J4bberwock, i guess the answer is no?!

Sorry, I didn't see the message earlier and it was quite a sad day here in France  :'(

To answer your request, the board uses 4 layers of 2oz copper, so no worries there.

Each pin on the PCI-e connectors is rated 9A.
3pairs x 9A x 12v=324W
So, the answer is yes, and we should even have the manufacturer's safety margin on top of the 324w.

Second thing to consider, your PCI-E cables are using 9A crimp pins anyway, unless you asked specifically for the 45750 series pins rated 13A that I'm using on request for a few customers who want even more safety.

And don't forget that usually, you are speaking of 300W at the wall, and drawn by a bronze PSU, so less close to 250w drawn from the PSU.

I'll ask one of the early buyer who is running 2 boards @3000W since before Christmas how many cables/which miners he is using.

Religion makes people more stupid than they are already...

I'll search a bit about the psu and maybe come back to ask for 2 bords :)

Thank you!

First batch of 200 boards is closed.
There will be a few extra boards in stock after the batch will be shipped.
I'll also try to ship up to 20 boards during the last 2 weeks of january with modded main connectors while waiting for the correct reference.

The first boards with 22 PCI-E plugs will be in my hands by the middle of next week to check them before bulk ordering.

Deposit will be collected during next week.

Any luck on a US distributor yet? Please verify that I'm on the list for the 22 PCIE boards for at least 1, but if you have enough I'll take 3. I'm picking up on of these PSU's now. Thanks so much for developing this. I've been scouring rcgroups.com on how to do this myself. I saw your recent post there as well. It seems they have a lot of info on this type of work but not much on how to do it yourself for the BladeCenter H or any supply that will handle this type of load. Do you plan or would you consider sharing tips or how to's for the do-it-yourself electronics tinkerer in the future?

Thanks again!!

There will be a US distributor for the boards. In fact I'll ship him a big batch in the first days I'll have them ready so he can dispatch the boards for small orders locally.

And everything is ordered to make at least 250 boards for the first batch, so there will be a few left.

The DIY isnt that hard, the pinout to start the PSU is available on rcgroup. (A5 to ground to start, and B2 to 12v to start the fans)
Finding the good connector reference is sometimes harder, but the easy way to do it is to buy the power backplane that goes behind the PSU in the server.

I'm not an expert for the PSUs, but xandrios posted a great "how to" on rcgroup for dealing with unknown PSU

I've tried every search possible to locate the "power backplane" for that power supply. Do you know the part number or have any suggestions? It looks like it might be a part of the chasis backplane assembly, but of course we're only interested in the plugs/connectors for the psu.

It's a pain somewhere to find them, and they aren't cheap.
IBM 25R5780 BLADECENTER H CHASSIS MIDPLANE BOARD
around 200$ a piece for 4 connectors on each midplane

http://www.serverworlds.com/ibm-25r5780-h-chassis-midplane/

How many positions has the connector have?

1. There's this one from Digikey, but it has only 35 positions i.e 24 signal and 11 power.

3. This is also 24 signal 12 power, but has a twist to it ... seems to be a male one

http://media.digikey.com/Photos/TE%20Connectivity/6450128-8.jpg

The correct one is 51940-046LF (6P 20S 6P). The reference is clearly readable on my boards.

Spacing between the power blades isn't the same on most of the other connectors that can be found.
0.20"(5.08mm) for the good one.

Most of the connectors you will find will have 0.25"(6.35mm) spacing, some will have 0.30"(7.62mm) spacing, and I even found some wixh mixed spacing.

I even searched TE connectivity, Molex and another manufacturer for something that is in stock and will fit.

Number 2 looks like it might work. Below is a picture of the back of the supply. The PSU looks to have 20 signal. I doubt they would line up appropriately or the spacing might be too wide. Awesome site though. I did find this through browsing and looks like it might be a match. Need to look at P7 though on the datasheet. Looks weird. Unfortunately, no stock a min order qty is 264 @ $6.18/ea. Not a bad price if it is the correct connector and there are enough orders. Might be able to request a sample or a smaller amount?

Let's continue searching... (looks like J4bberwok had already replied)

Could you turn that PSU over and see if there are any markings on that connector? If so, could you try and read them then transcribe it here?

@J4bberwok - I can not find that part number anywhere, not even on the FCI site, so looks like it must have been a custom one. It does look like a powerblade connector nevertheless, and though I have seen a 6P 24S 6P, I can not find a 20S one, but short of it being custom, I am sure one can be found ... just a matter of looking for the right MOQ's.

There is no image for this (http://www.digikey.co.uk/product-detail/en/51939-045LF/51939-045LF-ND/1491654) but the datasheet (linked from that page and also here (http://portal.fciconnect.com/Comergent//fci/drawing/51939-045.pdf) seems to fit the connector (see extracted image from datasheet) - MOQ 264 unit @ 4.39186 = 1,159.45 GBP (expected 20/02/2015 as of today)

http://s12.postimg.org/am2ehsqlp/IBM_Connector.png

I have Jerry rigged one supply to play with it until J4bberwock's boards are ready. Works find but the fans are loud. Can not even here the S5 beside it.

Does any one know what the other control pins do. I was able to find a diagram that showed only how to power on the unit the fans and how to increase voltage by .5, would be nice to under stand all the controls.

Sent you a PM a before but i will take 15 for now.

Doug

Update,

I should be able to deliver early for 20-30 boards using modded connectors.
I just got the first boards finished using it, and it works exactly as the original one except it's a little more expensive for me, and I need to cut the connector to fit.
No price change for you.

https://i.imgur.com/THdbHBtl.jpg?1 (http://imgur.com/THdbHBt)

If some of you are interested in earlier delivery with those connectors, let me know, and depending on how many I can have done, I'll divide them among you.
Shipping is expected by the 19th of january for the boards with modded connectors.

It's the opposite gender, and power pin spacing wasn't good anyway.
Here is the correct datasheet. the "5x5.08" power pin spacing is mandatory.

http://www.datasheets360.com/pdf/-5473380759948139508

The 51940-046LF is 140-150 pieces MOQ, but I already ordered 250 that I should get by the end of january, and a second batch of 250 should reach me before the end of february.

Looking forward to it!! My PSU just arrived today! Just need the board and I'll be set.

One last thing that we need to take care of, the cables.

The question is who will need cables, and how many of them.
Since sourcing them usually takes 2 weeks from order to delivery, it's the good time for you to order (from me or someone else, as you wish)

My home made cables are using 1.5mm² copper wires.
according to tables, 16AWG is 1.31mm², 15AWG is 1.65mm²

Price will be
2.5$ for 24"/60cm
3.5$ for 32"/90cm

I can also source cables with 16AWG aluminium wires, the price should be 0.6-0.8$ cheaper than the copper ones.

For those of you who'd want to make the cables or add a connector to existing cables, I'm also able to provide the crimp pins and 6 pins connectors at a fair price:
0.20$ the 6 pins connector, and 0.04$ the crimp pin

How many pcie connections can they accommodate?

Peace  :)

I am not sure how the control pins are labeled but I found a diagram that showed looking from the rear , the upper left pin to ground turned on the supply and right most pin on the second row to turn on the fans, This seams to be working but am I doing it the wrong way ?

This would be a question for J4bberwock.

Yes, I'll take some cables as well. Since there will be 22 PCIe connections per board, I'll start with enough for 2 PSU's (44 cables); 22 24" AND 22 32" / copper 1.55mm²

I might make the next set myself since I would like to learn, but so many different 6 pin molex connectors. It will take me a while to figure out which parts are the right ones. Seems like there are pitch differences and probably others. I have a lot to learn :-)

I have a test unit set up with 5 Antminer S5's , The Bladecenter appears to be handling it OK. but I think this has got to be close to the max for it. I am wondering if it would be safer to just run 4 per Bladecenter. Can't complain about how loud the S5's are since you can not hear them over the Bladecenter's fans.

drawing 3180 watts at the wall
13 Degrees C air temp increase from input to output
 .998 power factor

Awesome! I've got 4 S5's arriving tomorrow and already have the PSU here. How did you "rig" yours up until the board is available? Do you have pictures? I thought the S5 only pulls around 560W x 5 = 2800W. The BladeCenter H PSU's are 94% efficient 3180 * .94 = 2989W that your S5's are pulling or 597W each. So, it's all pretty close I guess.

These breakout boards have been performing flawlessly from the very beginning. The power supplies themselves are big and beefy but that only helps to keep them cool and efficient. When I load a DPS2000BB near 100% the custom fan job pushes some serious hot heat out of the unit. I have had almost a 30%+ failure rate on those units because of inadequate cooling. These get warm but I wouldn't say hot. I have noticed if the AC is plugged in but the power switch is off on the breakout board, something is still running, as the pws will get quite warm. A good tip would be to unplug or remove AC power after switching it off on the breakout board.

if someone can get full engineering drawings for this connector I can make a 3d model for them.  Then anyone can print them out and just use J4bber's boards like a DYI kit.

That would be great but unfortunately you'd still need the metal connectors, and I doubt we can get them without buying full conectors.
And of course, I assume the connectors are patented. You'll have to design some kind of "generic" holder for the metal contacts.
It's probably doable, but it's not worth the effort unless you need small quantities of connectors and they don't have samples available.

As for DIY kits, if some of you are interested in it and have the skills to do the soldering job, they can request unassembled boards.
Beware, because of the 2oz of copper, and 4 layers, heat dissipate quite well, so it isn't the easiest thing to solder by hand.
It's better to have the PCB warmed at 100-150°C before soldering.

I'll also update this week-end with pictures of the finished 22 PCI-E revision boards since I received the PCBS this afternoon.

Uploading pictures won't be possible earlier because I'm currently without phone and internet access, I'm using my mobile as a modem...
Hopefully it's supposed to be fixed tomorrow.

I hope you fix your ISP connection soon cause I am just waiting for your reply on my PM.

Here are some pics of how we made the harness. My buddy owns a cable manufacturing company and even using $120,000 of equipment, the time and effort was not worth it. I only made these because of the delivery time to get J4bberwock boards for the first 52 Antminer S5's. I highly recommend not even consider doing harnesses and just buy the boards.

The equipment we used  to do this project was an auto feed wire cutting and stripping machine that did all the 10 gauge black and reds. Then we used  an automatic stripping machine to get .6" on the pre-made PCIE wires we got from klondike_bar. An ultrasonic welder was use to join the wires. Had to use a 150 watt soldering iron to join the welded pads to the power supply.

There is also a shot of the power meter when the room was hot and the fans were at max, it was drawing 3785 watts.

I can't believe how loud these are.  I have an extra PS, it looks like the top panel can be removed almost in one piece.  I have a buddy that can laser cut sheet metal.  I might have him cut out two openings  so I can put two 140mm fans on top.  I just dont know if the logic board will throw a fault because it doesn't detect the original fans to be on.


3785 watts?  2880 with 94%n is 3053watts  how is it more?

I have no idea, going to test a few and see if they draw differently.
I do believe the power supply will work with out the fans. But if not cooled it will self distruct.

First post updated with picture of the actual 22 PCI-E plugs design.
First boards with modded connectors shipped.

Hi:

Do you know where i can find a cheap Bladecenter H PSU , i found delta 2000 on minersource with the price of 29 USD. But i prefer to look for a larger PSU with fan.

Thank you.

For the US market, there were a few of them available on Ebay, around 50$, I haven't checked recently.
The guy who will resell the boards for small orders in the US should also be able to sell the PSUs.

Thanks.

anyone can give a hint, where and how to find the female connector for a 8 (4+4) -power style PSU like DSP1520?

I am very interested in this supply.
I sent a PM about being involved in the next batch.
I am in the US.

Look on digi-key or farnell. You can also post an image here and I am sure if anyone knows where to source them you'll get advice. If you are posting an image, it would also be nice to read any text / branding on the connector and post it here .... the manufacturers are usually molex or FCI (branded powerblade or PWRBLADE).

I spend 1-2 hours on these sites and did not find it 100% sure, because missing product pictures or drawings.

http://www.anony.ws/i/2015/01/25/dps1520pins.png

It would also help me to find the correct names of these "6mm twin copper contacts " to find seperate 4 plug female connectors. I Don't need perfect solution.

OK, thats a good image ... is it a dell PSU? If so then it most likely is an FCI connector and it is called an 8 power 24 data connector ... or that is what you search for on digi-key, I did a quick search and here goes ... hover over the images to see
http://www.digikey.com/product-search/en?pv1003=67&FV=fff40016%2Cfff80442%2C1600015&mnonly=0&newproducts=0&ColumnSort=0&page=1&quantity=0&ptm=0&fid=0&pageSize=25

EDIT: I think one of these is your connector (on that search above). you need to make sure of the dimensions first though!:

thank you!!
that's obviously exact the one.
Unfortunately they ship either big quantities only or shipping costs to europe are much higher than 1-2 connectors.

So as a workaround it still would be nice to find the correct names of these "6mm twin copper contacts " to find separate 4 plug female connectors may be at other vendors or shops?

Usually, digikey have free shipping when you hit a certain threshhold, all you need to do is get a few bits and bobs from them to make up that amount. But just like this thread, you can set up a group buy for your connector types, or offer them for re-sale on this board (I know I am going to be doing that soon!).

I am afraid I do not have any information as to the name of those twin copper contacts or whether you can get them separately, but the workaround I used up until the time I "discovered" the correct connectors for my server PSU was to solder the wires directly to the copper connecotrs. It worked very well then and still works on the units I've not have the chance to "upgrade" yet.

I have some connectors for this PSU in hands.
I'll have a look tomorrow to be sure, but I should have at least 4 of them.
Part number: 51915-101LF.
Datasheet: http://download.siliconexpert.com/pdfs/2010/12/26/3/4/38/223/fci_/manual/51915-101.pdf

No stock anywhere

You'll need right angle ones since the PSU covers the power connector.
If you want to use at least 5 PSUs, drop me a PM, I can have breakout boards ready in 10 days for this PSU.
It was on my "maybe" list.

There will be a US reseller for the boards, so you'll be able to save on shipping..

Thanks for the reply.

I can solder, have access to any wire type needed from probably 24 ga (probably smaller if we needed it) to 4/00. We have a department which prefabs all of our boxes and misc stuff. I should be doing more in there than buying these break out boards but they sincerely add functionality I would never take the time to add. I do not have anything from you yet, but I do have a couple of the GekkoScience boards with a few of the DSP2000s and plan on getting more.

Maybe I haven't looked in all the right places, but it seems like these larger power supplies are hard to find. Do you foresee a problem with finding replacements or adding more down the road? Do you have a "go to list" of dependable people?

I prefer dealing with folks I meet through the forum or people you recommend.

What is the median price for those PSU and how loud are they ? Thanks :)

PSUs are usually around 50$ in the US, and noise level is like most of the server PSUs with fans, let's say vacuum cleaner.

Thanks :)

Like a high pitched 16amp upright vacuum.  If you have thin walls, the sound will go right through.  You definitely cannot live in the same building with these.  It's well above 80db.

I can post a video if people are interested in hearing them, but they are loud.

i would thanks ! :P

Yeah Im curious what is the sound of these beast!  ;D

I want to make a recognition to J4bberwock.

I have received the breakout board and the cables and I can say they are of very high qulaity - everything works.
The only thing I noticed as an issue was poor contact between IEC-20 socket and the small board for feeding power to the PSU - there have been some sparkles plugging the power cable into the IEC-20 due to the poor contact.
I disassembled the IEC-20 from the breakout board, adjusted it and then assembled again all parts back and it's fine now.

Overall - very good product quality.
Thanks J4bberwock.

As for the noise from the PSU - I have never heard anything that loud so far concerning bitcoin mining  :P

Thanks for the feedback.
From what you said, it seems that I forgot the soldering of the C20 plug to the small board.
It's the last step of the assembly process.

And that's why you got sparkles.
I can exchange the board if you wish, or if you have access to a soldering iron (almost any would work), you can solder the 3 pins of the C20 socket to the small board.

hahaha thanks !

Forgive my "newbieness," please...

Can I hook up my S3's to this PSU with your boards until I get S5's?  My guess is that it would be okay even though it would be 648 watts available to each S3 via two PCI-e connections; the s3 would only use what I have configured it to use [if I over clocked it]... correct?

EDIT:  Apparently I can use this 2880 watt IBM PSU with my S3's.  I like the way McHouston has his set up:

https://i.imgur.com/DzOiYP9.jpg

I thought you've left them like that on purpose. I am not a soldering expert but replacing the board over 3 simple soldering points would be pointless. I will ask a friend who is more experienced than me with soldering equipment to do this. Just, if you can post some picture how it should look like after being done will be good.

Hello Sir,

I need to order 3 of your breakout boards for the IBM 2880, please.  I also want to order forty-eight (48) of your home made 15AWG 1.65mm 32" cords.

I plan to order many more IBM 2880 breakout boards later.  This is a start.  Your business would be appreciated greatly!!!

Do you just send me an invoice?  What is the method of payment?  Please let me know how to initiate an order with you.

Received my boards and cables this week. J4bberwock provided excellent communications, products, and service! The boards and cables look and work great! The plastic standoffs that attach the board to the PSU frame are a really nice touch. This really anchors the board to the PSU frame. The cables are also top notch. I definitely would purchase from J4bberwock again. I just need more miners now :)

Keep up the great work!

Thanks for the review.  I ordered 60 15AWG PCI-e cords and breakout boards myself.  I look forward to seeing and using his products.

Thanks again for the review!

Currently assembling boards, I'll take some pics tomorrow.

I'll have a big batch ready to ship on monday, and the remaining orders should be shipped before the end of next week, I'll message the buyers 24h before shipment so they can make the final payment once I've weighted the packages.

Next batch of boards will be ready end of february/first week of march.
And starting in march, I have scheduled deliveries for the connectors every 2 weeks so I can always sell more or less from stock.

Sounds Great!!!

Thanks again for the hard work; with little sleep at that.  It's really appreciated!!!

Best Regards!!!

First post updated with what have been shipped as of today.
the remaining boards will ship on monday.

Everything I ordered arrived in the U.S. from France in good shape.  Breakout boards were bubble wrapped and protected very well.  The quality of the cords look great!  Thanks again for your hard work, Sir!  I hope to be ordering quite a bit more from you in the future!

Nice!

8 breakoutboard!  :o  You got a nice farm! What are you using?

Here is the link for anyone looking for boards in North America:  https://bitcointalk.org/index.php?topic=966135.0

If you mean what rigs am I using, I have this at the moment [Please ignore the mess; will be cleaner when moved to the next closet]:

https://i.imgur.com/A7W9wF9.jpg (http://imgur.com/A7W9wF9)


Here is the closet I'm presently working on.  I have an exhaust fan on the way for this closet.  It should be here Wednesday or Thursday.  I also have fifteen (15) SP20's on the way.  They should be here Thursday.  I also need to finish the power going to this closet as well.  I'm presently doing taxes.  I will finish taxes first; then get this closet finished and mining sometime next week.

A window is centered in the back inside this closet where a 7,800 CFM exhaust fan will be installed.  This structure is large enough for 96 S4's or 192 S5's.  However, I'm not sure what all I'm putting in it at this point in time.  I have plans for moving to another State with cheaper power than where I am presently.  I may wait to purchase more rigs when I move to that other State rather than spending money on upgrading power at my house here in Alabama.

I purchased more PDU's as well but I got horizontal versions this time to save some money.  I will be making whips in the future when I move to another State.

https://i.imgur.com/I9TeKO1.jpg (http://imgur.com/I9TeKO1)

dmwardjr your closet is super nice. Is it effective to dampen the noise?

Thank you!!!

I believe it will be.  I have four (4) 25" (w) x 14" (h) grilles in one 36" (w) x 84" (h) door at the moment.  This closet has four (4) of those 36" (w) doors [2 on each side].  I'm only putting grilles in the doors as they are needed when rigs are added.  You can see 4 grilles in one of the doors on the back left.  I will also custom make a means of holding filters in the grilles that can be replaced periodically.

I built this closet downstairs in the recreation room.  It naturally stays cooler downstairs since cool air descends and heat ascends.  It will be much easier to keep the sound to a minimum downstairs in the basement.  Having them in my present closet reduces the noise dramatically.  The door to that closet has an 18" (w) by 25" (h) filtered grille installed in it.  There is a huge difference in noise with the rigs inclosed in structures like this.

Thanks for the breakout boards!

These 2880's are loud!

Sweeeeeeeet!

If anyone from the initial group buy in North America has any problems with any of their boards, I would be happy to have replacements sent out immediately on behalf of J4bberwock.  Send me and J4bberwock a PM if you have any defects at all and we'll get you sorted out.

I live in the USA but I bought mine straight from J4bberwock.  I bought 8 of them and 4 of them turn on the PSU but do not turn on the fan.  I'm going to tear away the white glue stuff and make the following solder connections myself...

https://i.imgur.com/qiFVfJB.jpg (http://imgur.com/qiFVfJB)

If this voids any type of warranty on them doing it myself, please let me know.  I've made thousands of solder connections.  I know what I'm doing.  For example, I engineered, designed and built these training boards to teach telephone technicians how to use their meter to identify and locate troubles.  The training boards have 192 solder connections each and the master board that connects them all together has well over 200 solder connections.  The entire setup has 6 training boards, one master board, 3 bride tap boards and one power supply.  I've made 6 sets up these training boards.  Each set has a total of 11 cases.  So, a total of 66 cases.

Picture of one of six training boards below.  Each board has the same resistance as 19,700 feet of 24 AWG wire and each board has the same capacitance as 19,700 feet of Air Core Cable [Not Jelly Core].  1,700 feet of the 19,700 feet is actual real wire.  I needed real wire for when I teach them how to use a Time Domain Reflectometer (TDR).

Picture of 3 of the 6 training boards, power supply, 3 bridge tap boards and one master board.

This is a picture of a class I taught in Leesburg, Florida.  I did a total of 22 classes in Leesburg with 12 technicians in each 4-Day class.  You see the 6 training boards connected to the black master board in this picture.  The power supply and 3 bridge tap boards are underneath the table.  I teach them how to use their JDSU HST 3000 to identify and locate troubles over a 4-Day period.  I wish I had them 2 weeks but I'm forced to teach them what I can in a 4-Day period.

https://i.imgur.com/8Ay71uQ.jpg (http://imgur.com/8Ay71uQ)

I was up until 8:00am this morning [All nighter!] installing the new fan, setting up the rack, PDU's, PSU's with PCI-e cords and rigs.  I still have more rigs to bring over into the new closet [You might see them in the other closet in the background].  I'm waiting on a couple more 240 VOLT/30 AMP outlets to arrive from Amazon tomorrow so I can add another PDU.  Then I will be able to bring my router, switch and other rigs into the new closet.  I have to leave the door with grilles open at the moment to allow the 15 feet ethernet cords to reach from the switch to the rigs in the new closet.  I will be very happy to get those outlets in the mail so I can get that switch inside the closet to close the door with grilles.  I will clean up the wiring with zip ties when I get all of the rigs in the new closet.


Pictures of what I've done in the transition over from the old to the new closet thus far:

https://i.imgur.com/mANMnOS.jpg (http://imgur.com/mANMnOS)

Don't be fooled... The fan is not held up by zip ties [lol].  The next picture shows the clips holding it in place.  The entire fan is resting inside the circle I cut in the wood with a jig saw.  The clips are holding the fan in place while it rests on the wood.  I found there was no need to screw a bolt through the black hanger into the joist above.  The fan rests perfectly on the wood while it is pushed through to the outside approximately 6 inches to where the handle rests against the wood.  So I decided to attach the handle to the wood to hold the fan in place.

The reason I have more wood to the left of the fan is to allow space to mount my power outlets, etc.  I will mount the outlets in place later.  I was tired last night!

The next two pictures show you how I hanged the IBM 2880W PSU's with tie wraps to keep them off of the SP20's.

https://i.imgur.com/maNEllU.jpg (http://imgur.com/maNEllU)

does your fan vent in from the outside or TO the outside....

btw: really nice work!!!

Thanks very much!  Still a work in progress.

It's sucking the heat out to the outside.  That's the most important thing... Getting the heat out; rather than trying to overcome it with AC.  I will upgrade this fan from 7,800 CFM to 22,800 CFM when I add another 60 TH/s.

A little more has been added to it.  41.4 TH/s that is under clocked to 35.4 TH/s at the moment for better power efficiency.  All of the S3's have been upgraded to the latest firmware to under clock by varying the frequency and the voltage [All S3's at 193 MHz and 0625 volts for 380 GH/s to 400 GH/s each].

Those Corsair's will be replaced with 2880W PSU's once I've finished my taxes and made some solder connections on the breakout boards.

https://i.imgur.com/t7UoZWO.jpg (http://imgur.com/t7UoZWO)

This is the man who has it going on right here!  Very nice set up you have there, Sir!  Are you enjoying the Neptune's?  I know you are enjoying these 2880W's and the breakout boards.  The breakout boards really make things easier.

j4bberwock, do you have any more of these boards in stock?  HolyBitcoin doesn't have them listed as an available product.

I'm currently finishing the assembly of the first batch after some trouble with out of specs connectors.
For the US market, you can contact Finksy, he have them in stock.

Do you have reseller or supplier in Australia?

No, but I can either ship them myself for now, or have them shipped from US.
I already had a few requests/buyers from Australia for my different boards, so, depending on the potential market size, someone who wants to resell any/all of my boards can contact me.

Hello, maybe you can tell where i can buy many of Astec AA23920L? And your boards for that will be next step =)

Thanks.

Depending on where you live, Ebay may work fine. You can use bladecenter H or 2880w (sometimes 2900w) as key words
in the US, it's not unusual to find the PSU for 50$ shipped.
In Europe, prices are closer to 80$

Boards are now in stock, and I have enough components available to allow fast turn around even on 50+ orders.
I'm away for the next 8-10 days. For all new orders, next shipping day will be on the 4th of May.

Hi, I need know, what is model and number?

or https://i.imgur.com/mqiLuKk.png (https://i.imgur.com/mqiLuKk.png)

thanks!

J4bberwock, Im waiting for your reply about my order,

Thanks

You got PM (and tracking info).
Sorry for the extra delay.

is it possible to connect cables directly to the boards circuit ?

J4bberwock, payment sent, please see PM for delivery address.  looking forward to receiving my boards!

So I bought a couple of break out boards a few months ago and it seem they are not working now? The fans on the psu wont spin , I thought the psus were bad ( 2880 IBM ones )
But I got two brand  new psus off eBay and its the same deal, first two green lights go on
Psu starts to get super hot BC fans wont activate

I've tried sp20s ants 🐜. Any ideas?

The PSU's can go bad but they are pretty stout. I had an on/off switch break off when I dropped one from 10 feet. I bent and jammed a paperclip in the remaining switch to short the pins to turn it back on again.

One of those green lights tells you the AC power is on, the other will tell you when DC power is there, and that will only happen if the power supply is good and the switch on the back of the board is flipped on.

There are two orange lights for a voltage error and a fan error, I have never seen any of these lights activate yet.  If both AC/DC http://coloradok5.com/forums/images/smilies/peace.gif power lights are on but fans are not spinning I would say the fans are dead somehow. There is a part number for just the fan replacement but the power supplies are already so inexpensive its probably the same cost just to get another power supply.

These are return psus right off eBay both of them can't be DOA can they?

You sure its not the adapter not working properly?

I have had about a 96% success rate in these used power supplies. I have yet to have one of these breakout boards go dead. Even the prototypes I received back in December are still ticking strong and have many hours on them now. The breakout board has nothing to do with the fans at all, that is all done inside the power supply.

So if you see one light with the power switch flipped to off, then when you switch it on you see two green lights, and still have no fan - it is most definitely the power supply.

Well, I had a few of mine do what you said, made the proper solder connections on the breakout board and everything is just fine now.  Meaning it was not the power supply.  Be careful of making flat statements.

I'm not saying this to discredit the breakout boards at all.  I absolutely love them!!!  I just thought the record should be set straight.

If you have had this problem you should elaborate exactly what you had to solder to fix your breakout boards for the previous poster that is having this issue, instead of just telling me I'm wrong. Nothing is really accessible anyway. I'm curious exactly what traces you are correcting. J4bberwock can easily confirm if a defect in his board could ever precipitate this issue. Out of the 68 boards I have been running for over 6 months now I have had no issue with any of them in any case. I just paid for 50 more.

Hi, it will depend on the date you ordered the boards.
The very first batch had some trouble because the pins dimensions were out of specs, so the contact wasn't perfect on the signal to turn on the psu or the fans.
The batches after that have signal pins soldered systematically to avoid any trouble, even if the pins are now to specs.

You can probably see even without removing the white plate if the pin to turn on the PSU is soldered

https://i.imgur.com/qiFVfJB.jpg (http://imgur.com/qiFVfJB)

the one under the "n" is usually visible from the outside.

the one in the square under the "H" turns the fans on.

Well I'll be a monkeys uncle. I must have gotten lucky then your prototypes must have been before that first batch. Good info to know if I ever have this issue.

He already posted about it in my thread, and the picture I took to explain what to solder is in his post too.
The very first 100 boards sent in February suffered from this defect. All later batches have the signal pins soldered to prevent any trouble.

On a side note, I'm on vacations right now.
I'll be back home on friday or saturday, your order will ship on monday

Good catch

I was able to fix one of the breakout boards by resoldering the contact , now the PSU works so fuck me I have 2 extras of these PSUs and nothing for them to
power if you could have told me to check that bit on the breakout boards when I first had the issues could have saved me a bit of cash. I'll have to feebay the extra PSU's

The other breakout board seems to be toast probably would have to take it apart to figure out what's wrong with it but yeah its the breakout boards since the one I "Fixed" powers the fans on all the PSU's now even the used ones I got from you.

If you soldered both pins on the second breakout board the last thing that can fail is the switch.
There are two holes next to it that I use for testing purpose and can also be used for a remote switch. You can connect both holes with a paperclip to bypass the switch. Spacing is also correct to solder 2 pins and use a jumper.

I'll take a look at those two holds and

I didn't solder anything on the other one (not working one) , I looked at all the pins and they seem to make contact.  The switch works though since the unit actually powers on , I'll send you a PM for another  two breakout boards and worry about fixing this one later.  I don't have anything for these units to power until I get my alcheminer fixed though.

Can anyone tell me how loud is this PSU? i am considering to invest some serious cash in one , but the loudness is a problem for my mining operation it needs to be clear to silent. :)

then this is too loud.  what are your power needs? 2000 watts? 1500 watts?  2880 watts?

about 2300watts. running atm 2x 1000w pc psu but i need about 1400 for one machine so lacking 400w :)

This is pretty much the loudest PSU on the market. 3x high-RPM server-environment fans running full rip is akin to a jet engine.

My apologies, LordPaco.  I did not mean to disrespect you, Sir.  That was not my "intent" at all.  I assumed you had already seen the post in this thread regarding the solder connections needed for the fans to work.  This was discussed earlier in the thread before.  I assumed you had already read this in earlier pages in the thread.


I live in the USA but I bought mine straight from J4bberwock.  I bought 8 of them and 4 of them turn on the PSU but do not turn on the fan.  I'm going to tear away the white glue stuff and make the following solder connections myself...

https://i.imgur.com/qiFVfJB.jpg (http://imgur.com/qiFVfJB)

If this voids any type of warranty on them doing it myself, please let me know.

I did follow up with J4bberwock about this fixing the problem after making proper solder connections but I did not follow up with the thread.  If I had done so, we would probably not be having this discussion.

So, again, please don't take my comment as trying to win points in an argument.  That was not my intent at all.  I simply wasn't thinking.  It must have been when I was very tired and not thinking straight.  I'm up at all hours of the night quite often.

I like you, LordPaco, and I love what you are doing with your farm.  Keep up the great work and I wish you the best in your mining endeavor.  

Cheers M8

Is it possible to Modifie this PSU.


I i cut 2 bit holes on top and put 140mm fans or 120mm fans should it run smoothly ?

That's an inspired thought ... if only to reduce the pitch of the nosie from its fans. It should work if the fan has comparable (even better) airflow, and I'd suggest you'd be better off putting the inards into another (new) enclosure altogether, that way you can focus the airflow from the 120/140mm fans ala S5 printed mods ....

Yes it is possible, this was my hack job:
http://i62.tinypic.com/n63upl.jpg

Although I have not had a chance to mess around with it and get the PWM hooked up, it is a possibility to run this at full load.  Another member graciously shared his IR thermal images of the PSU right after shutting it down and removing the lid to show where most of the heat emits from:

http://i57.tinypic.com/2wdccy8.jpg
http://i61.tinypic.com/104ruvq.jpg

Interestingly, heat was not concentrated where I would have expected (with my complete lack of electronics knowledge mind you), and had I seen this before modding my case I may have re-thunk my fan layout. One important factor was blocking most of the airflow through the ventilated panel where the original fans mount (the front in this last picture), to concentrate more airflow towards the backplane/breakout board connector end, as it appears there is a large amount of heat emitting from under that center thick aluminum plate. 

Also, I do not suggest removing components and re-mounting them in a new chassis, it would be a complete waste of time at best, and potentially dangerous at worst.

Thanks, this is what i was wondering, i saw modified 2000bbb  PSU like this, tought the modification could work.

How is the noise now? i am trying to get my system silent, right now it don't emit sound above 21db around that.

Most says that this PSU is high pitched so close to silent i am looking for.


Is the little fan connected to internal fan wiring ?

The larger fan is a ~4A delta, so I didn't bother trying to connect through the PCB, I fed power directly from a PCIe plug.  With these fans at 100%, it is not much quieter than the stock 3 fans, and again never got around to getting the PWM from the board working.  Maybe J4bberwock can chime in, I know he was working on something himself as well.  In my experience, these PSU's are not good for someone looking for a quiet solution, it is just too much heat to be dissipated in a small case volume, you would need to run less Wattage on these to get away with a quiet fan solution, and that pretty much defeats the purpose of these PSU's to begin with.

Yeah this is what i am afraid of, i am on a closed enviroment, the ambient is about 38celsios up to 40 when the machiens been up for like 3-4 days whit no rest.

I might consider to run dps 2000bb maybe ?.

Prices are about the same of them two psu's but i am looking for the better effience.

I was thinking to maybe cut open the entire top and put 4x 120mm fans at 7 volts , could this take care of the bussines ?


I need to run about 2400 watts, sp20 and C1 , and one coming s3.

I'm trying to buy the breakout board, but I don't know where. Please help ???

Contact Finksy or J4bberwock.

Finksy does USA and Canada

J4bberwock does Europe

Temperature does not seem to be a particularly large factor for these PSU's, they have very effective thermal shut offs before damage appears to take place.  I've had a couple running for nearly a year in a similar ~300 sq ft environment that is almost completely closed off with minimal exhaust for heat.  In the summer months, they would hit thermal shut off sometimes once a day.  In the morning when I get back I power cycle them and they come back on every time.  It's certainly not recommended, but my experience has been that they are very tough when it comes to heat (this is using stock fans)

At the end of the day a PSU is a PSU, in that if you are trying to dissipate 2000W of heat with 4 fans, there shouldn't be a significant difference between models (only the frames for airflow).  Meaning, if you could get away with 4 quiet fans on a DPS2000BB, I can't see why you couldn't get away with the same wattage using the same fans on a IBM 2880W.  And inversely, if those 4 quiet fans can't keep the IBM 2880W cool at 2000W, I don't see how they would fare any better with the DPS 2000BB. That is my opinion anyways.

Noise on the other hand, I am not entirely sure if it will be suitable for you, as I don't know what your expectations are.

Yeah i understand, 2x 80fans is supposed to be silent on the 2000bb, but it is fanless at stock, so as u say i am guessing that 3x on a 2880w should not be a problem, maybe just put a 220mm fan on the top blowing into the case?.

The DPS2000 BB isn't fanless, the fans are inside the server.
If you don't add fans, it'll switch to overtemperature protection after a few minutes of use.

Regarding the bladecenter H, my best results with fans on top like on Finksy's picture gave something close to stock S3 noise level.

 On a power supply, you're only dissipating the heat caused by lost efficiency, NOT the total capasity of the PS.

 If your 2000 watt PS is 90% efficient, it's only needing to dissipate 200 watts (the "lost" 10%).

Yeah exactly and i might be loosing 300w on my psus at 80% efficiency.

So it will be 100w heat less, i think that 60c from 1x psu is better than having heat from 2x 60c.

So i will have the room a bit cooler then.


I think that putting  220m fan on the top and lower the exhaust RPM it migth be even good by just having 1 exhaust runing ;)

I am aware, thank you. I was over-simplifying and referring to 2000W's PSU worth of heat, not the full 2000W of heat (the fact that the PSU doesn't put out even a fraction of the heat that the miners it runs make this very self-evident).  

Larger PSU's = more heat than smaller PSU's, and the difference in heat output between different efficiency levels of the same wattage server PSU's is not going to be all that significant in the framework of choosing fans.  Meaning -as the point of my post was- if you are running 1800W of power through a DPS-2000BB or 1800W of power through the IBM 2880W, if a fan solution works for one it is very likely going to work for the other.

Sent you a PM for one.

How long do we need to make the male to male 6pin wires to spoil up a s5+?
To hook up one of these boards?
Thanks in advance.

It really would depend on positioning.  It has 3 modules with it.  If you start at one side and go to the last module and go to the 3rd hashing board on it, that is a decent length.

But with watt's are you just going to first 2 modules (6 hashing units within them) and controller unit?   This would be 7 PCI-e cables on that.

so I would like to be able to put a 2880 PSU with breakout boards on each side of the S5+ and power should be good enough to spool this thing. I was looking to find it efficiency or Db levels change. Also I want to be ready for the s😄7's
So total 10 male to male PCI-e 6pins total length 24"? 3 for each modules (3)=9+ controller

Two of these is really a over kill though.  One of these to power 2 modules and one controller.  And I would use a smaller one to power last module.  But I would agree one on each side off miner if you are able to do it in your setup.

Tomorrow is a little busy not sure if I can get out there with something to measure or not.   I can tell you if you can find length of bitmain PSU it worked fine.   I used 3 of them.  Have 2 on one side and one on the other. So that is another way to get measurements that might be quicker.

thanks I really appreciate it. :)

I liked this data sheet and wanted to make sure it remains.  So, I quoted it.

By the way, does anyone have a specification sheet on efficiency for the IBM 2880?

Soab,

What did you end up doing for a power switch, if anything?

I believe I prefer the breakout board.

You managed to turn the fancoolers without break board?

I can indicate that I tap pin to light source 2880

Any chance you could check your PMs J4bberwock, really interested in purchasing the breakout boards.

Hi j4bberwock .. do you have 2880w psu with board ?
and can be shipping to malaysia?

if you can't catch then try this site if you live in the US !!!


he sells the same boards , some you may have to ask for, he may not have listed.

If you contact padrino here on the forums, he always seems to have a bunch of these on hand:

https://bitcointalk.org/index.php?topic=1077136.0

I literally bought 10 from him last week - the breakouts are definitely the way to go IMO, and I love the 2880, it's a great supply...

Yeah the breakout boards look perfect for the job, I'm in the EU so would be best for me to get them from J4bberwock, unfortunately I think he is very busy at the moment.

I have boards and full packages in stock at this time as well, both the 2880W and 4K setups. 

Anyone in the EU happen to have these available and if so how many?

Need some breakout boards and cables. Anyone in the EU selling? I am in UK and new to this forum.
Thanks

Needed too, somewho knows where can i go?

Is this working for gpus?

it could be made to work but you still need an atx psu  to run the pc

Correct, or you can also use a "Pico PSU" to provide power to the motherboard, and use powered risers and provide power to the cards by PCIe cables.  The PICO PSU is powered by 12V so it can also be run from a PCIe cable from the breakout board.

if you know how to wire this correctly

I think it could work with the breakout board.

make sure to use 2 cables per gpu as a gpu will use around 180-240 watts  and one wire is hard to handle over 200 watts.

Hello,

As I have bought one of these Kits in the Past.
What a great Power supply and Breakout Board. Works Flawless.
Except for the Jet Engine in my basement.... LOL....

Now I have Inspired My Self to Ethereum mining, Off of a PC.

I would like to run the rig from this power supply.
As this Breakout board only has PCI Slots, I would also need a Motherboard power cable.
Do you have a way to do this? Or How would I do this?

I think I had seen I would still need a Power Supply for the Mother Board. I can't imagine there isn't a wire, or something???
Please let me know....

Thanks For your time.

the part I listed above needs for you to supply it with 12 volt power     so take a  pcie jack from your  2880

plug this into it

http://www.ebay.com/itm/PCI-E-6-Pin-to-2-2-1mm-DC-Barrel-Plug-for-Gridseed-Blade-ASIC-/262471607932?


plug this in the amazon part  and boom it works  or boom it shorts  ie make sure you know the dc is +- correct.


So the two parts should do the trick.  it is up to you to set them up correctly.

 I suggest using a cheap meter to check your polarity

https://www.amazon.com/General-Hand-held-Multimeter-Transistor-Function/dp/B00066ZZO4/ref=pd_sim_sbs_469_3?ie=UTF8&dpID=51M6I%2Bsk0DL&dpSrc=sims&preST=_AC_UL160_SR160%2C160_&refRID=5PSDH7J44KWMYY71YYZT

Ok, Yes I understand.

But really I would need more then this...

As this takes care of the Motherboard 24pin Slot, my mother board also has two 4pin slots.
So how do I solve that, will a 6 pin to a 8 pin work, or do I need a 6 pin to two 4pin cpu slot?
The Pico-Box only has 1 4pin???
Then I will need 6 pin to sata/molex for mother board power GPU Slots, Risers and Hard Drive's.

Am I missing anything else?

Thanks for your time.

DaPlayer

Still not sure what to do about the 2 4 pin power...

Also, Is 150-160 Watts going to be enough watts to power a Motherboard, Cpu and Cpu Fan ????

Thanks

DaPlayer

I suggest very little on this  because If you do it wrong you will kill the mobo.

So lets take this from a different direction.

On you mobo what are you looking to run?

better yet what is your mobo?

You can not run a large mobo with a lot of cards using a pico-psu.

So if you are looking to run 4 pcie gpus and a big beats of an eth mining unit.

the effort to adapt the 2880 to your needs is not much of a money saver and as you know will run loud.

there are ways to do what you want but they involve a lot of adapters  and won't save you the money you want to save.

below will do 5 cards
https://www.amazon.com/EVGA-SuperNOVA-Crossfire-Warranty-120-G2-1300-XR/dp/B00COIZTZM/ref=sr_1_1?

the frankenstein  2880

 needs the pico cost 40 need the power adapter I found cost  15 = 65

it will provide a four pin for your mobo not a 8 pin  so if you have a big cpu and want to drive a lot of cards you will have issues.  and be really loud.

the wiring is complicated and you are telling me you don't really know how.

that is good  since you do not want to kill off gear.

but if you are buying 4 or 5 or 6 gpus  get the evga 1300g2  and do not worry much.

me I never build bigger then a four card rig.  i build 3 and 4 card rigs as open rigs
I build 2 card rigs as gamer miners.

I have fucked around with enough psu's to know I would most likely not try what you want to try.
the wires will be sloppy and the build will not be neat.

Ok, that Makes sense...

Sometimes I just need to talk them out, to understand..... If you get my Drift.

I do understand what you are talking about, the amount of Adapters is crazy.
I do understand Polarity and wiring.
But technology moves quick, and terminology of hardware changes by the second...

I agree will look sloppy,
I did find a 4 pin Y cable, that would most likely solve that problem.

Looking at 3-4 cards, Sapphire r7 370's. Right now 1 on the MB with 2 risers.
MB: ASROCK H81 PRO BTC.
EVGA 1300W Power Supply

That is the exact power supply I have connected to it right now, that you Linked...

Since the 2880 PS, is next to My Open frame Ethereum Rig, I was just wanting to us that.
I could free up the EVGA 1300w for something else.

I was more worried about the 150 Watts of the Pico powering the MB.
Could all ways us a Cheap Power supply for the MB, and Power the PCI Cards with the 2880.
But I do understand, that power fluctuations can be a problem ????
But have seen MANY rigs using Dual PS...

Thanks For your Time...
Needed somewhere to think this thru...

DaPlayer Thanks You....

So who do i call to get those boards or the 4k BB packs in EU? I need to power up knc titan's so i need those plus small atx i suppose to power up knc controller

dmwardjr ...

What value is that resistor??? with the insulating tube on it, I just cannot make out the color bands.

I have a 2980W power supply........ the solder tracing looks abit different, I hope the pinout for that resistor is still the same.

anyone know how to reduce fan rpm? they are loud

I don’t know much about these either but looks like it needs some sort of proprietary power connector. So one guy was looking to open up a PSU and re-pin the leads. Something about it in this link: Repin a PSU for Supermicro X8DTT  server [url] (http://"https://www.serverbasket.com/shop/ibm-system-x3300-m4-tower-server/"/url)

I'm back in business after some health issues.

Boards in stock, and you can expect some new stuff soon for 2017.

New stuff? Sounds awesome. I remember how excited I was when the 4000w DPS boards were first announced. Now I own at least 10 of them.  :D

I'm a big fan of adjustable voltage and metered voltage as well. I don't mind paying a few extra bucks for the privilege.

Thats great news! I had to import Your boards from US... Cant wait for new stuff.

Limited time discount until the end of 2016 to celebrate the birth of my third daughter.

Any order will get an extra 10% discount no matter what the quantity is.
Orders over US$ 600 will also get a 60$ discount on shipping cost. That will make free shipping on most large orders unless you order cables or live in some exotic country where shipping cost is really high..

Orders will probably need an extra 3-4 days processing time since I'll be quite busy with my family.

Hi, are this board still on selling now? I need one to try, shipment to Italy.
Thank you.

me too interested

i would like to avail of this too! :)

@ J4bberwock

Hi. I sent you pm yesterday but I am afraid you just delete it because I am just a new guy addressing to a hero veteran.
Anyway I would like to buy 1 of these Bladecenter 2880w custom breakout boards. Just 1 board.
Can you please check my pm and give me feedback.
Thanks
darman

I have been trying to PM J4BBerwock for last 3 weeks but not getting any reply. He was fine in 2015 last time I bought some 2880 Breakout boards so I think something else may be wrong.
I know he had eye operations in 2016 but does anyone know if he is OK ?
Tx

Just an update, he is back and in business.  :)

hope still in business
for aug 2017 s9 14th/s batch what setup do you offer
have in stock for sep 2017 thanks

Is this project dead?
Can you sell me Breakout boards for the Bladecenter H 2880w PSU in kit if you don't have time to solder them?

I would like a few of these. Please respond if anyone has in stock or knows where to order.

Same here, looking to buy more breakout boards and 2880 PSU's if available. If anyone knows of sellers, please PM

Hi man! Do you happen to have breakout boards for Artesyn(IBM) PSUs?  Artesyn 7001374-y002

I can send some pictures if you need to see!

I have 4 of these on my hands and it would be awesome to be able to use them to something (mining) :D

do u have Bladecenter H 2880W Breakout Boards in stock would like to buy some
