LEASING CONTRACTS

I have started to offer leasing packages for use in approved Data Centre/Co-locations.  This can be beneficial for many reasons:

-Less upfront capital required, allowing more to be spent on additional mining hardware which can offset much or all of the cost of the lease

-Limits risk and cost of equipment failure, and associated down time due to failures

-Saves shipping costs for heavy PSU's to and from hosting location for duration of your contract

-No equipment depreciation

-Helps eliminate ownership problems associated with Group Buys, when more than 1 member shares purchase price of PSU to host together

-All maintenance, replacement, shipping, setup, and lost revenue from down-time due to PSU failure is my responsibility

Please contact me for details.

Shipping

Shipping will be calculated individually, to make sure you are getting the best rate.  All prices are in USD. I am willing to accept escrow through OGNasty, and can also do Paypal but buyer will be responsible for covering costs of either services (4% added to paypal, OG charges 1% for escrow).

Each package of PSU, breakout board & 10x PCI cables is approximately 16 lbs.

The BTC address for all non-escrow breakout board orders is here: 1GWQYCv22cAikgTgT1zFuAmsJ9fFqq9TXf
I will not PM you asking for payments to any other address, so beware of F1nksy, Fink5y, or whatever scammy names might pop up.   ;)



Original Post:

Hi everyone,

I am the official North American distributor of Break-out boards for the IBM 2880W Bladecenter H PSU's, which are 80+ platinum rated (94%+ efficient) Edit: UN-VERIFIED AT THIS POINT and have provision for 22x PCI-E cables.  Unlike other server boards, these don't rely on screw-down terminals and bare wires which can get loose and spark causing fire hazards, and limit the exposure of live contacts to surfaces above and below the PSU. Instead these use a double-sided PCI 6 pin cable, which only cost about $0.10 more than the standard PCI-6 to bare wire versions. Also, unlike the DPS-2000BB -which is the next largest server PSU available for miners- these have fans already built-in, so don't need extra work to set up up and deploy.  

The PSU's themselves are available on e-bay and elsewhere (I sell them as well), and the boards will be priced at US $70 $65 each (better pricing for bulk purchase, volume structure will be the same as J4bberwock's). Each PSU can handle 2x Antminer S7's, 3x SP20's, 5 Antminer S5's, or 8 Antminer S3's.  You won't find better value for power, and there are very few ATX-based PSU's that provide 80+ platinum efficiency (and none for under $200 for even 700-800 watts). Edit: UN-VERIFIED AT THIS POINT Lastly, unlike ATX-based PSU's, these can be run at (and I have found even over) their rated power, as they were designed that way for server use.  They do, however, require 240V input. Also, running these over at over 90% load will give you slightly decreased efficiency, and could affect their reliability.

I have personally taken 3x SP20's to settings around 960 watts (at ports, not at wall) each for approximately 2 weeks, and the PSU drew 13.41 amps (@ 235 volts - 3150 watts @ wall).  So at absolute full load (or possibly over), these will still hold over 90% efficiency.  Very impressive, and I will be testing different fans to reduce sound for home mining (fans on these PSU's are slightly louder & higher pitched than SP20 fans).  Sloopy informed me that he ran 11x Antminer S3's on a PSU for a while (over 3,300W DC!), but that is certainly not recommended, and will eventually cause the PSU to fail.  It is simply a testament to how tough these PSU's truly are, and that spikes over their rated output shouldn't affect performance.

Here are some pictures:

J'observe qu'il y a plusieurs Québécois sur se forum. Mon Francais est au niveau primaire mais je peux communiquer sans probleme.

Me gusta mucho aprender español, y tengo un conocimiento muy básico (con traductores). Pruebame, si eres paciente :)

Here is my PGP key for anyone wishing to send their personal information encrypted:


I will honour a 10-day return/exchange for PSU's or Boards that are DOA. However, these PSU's are used and although I try to briefly load test them all before sending them out, it is impossible to predict failures. As such, no warranty will be offered beyond what was previously mentioned. If you are looking for more peace of mind, please feel free to source PSU's yourself either new or used.

Very nice glad to see someone selling them in the US for faster shipping.

I have a couple versions of J4bber's boards for the IBM 2880W PSU and all work great.  These PSU's are beasts and will actually output slightly more then their stated output.  The best thing I have found is they handle heat very well.  Just make sure these units have airflow and they can take just as much heat as your miners.

The boards I have found works on all revisions of the 2880W PSU as well as at least one version of the 2980W PSU (Probably all of them but I only had one of the 2980W)

They do have quite a bit of noise when at full loud due to their small fans running at high RPMs, but other then that I can not find anything bad to say about the boards or PSU.

Good luck with the sales.

are the 24" standard 16 AWG cables pci to pci or pci to bare wire?

Maybe I'm missing something, whya re you double the price as the official reseller?


I know your local, but that's a lot of extra coin for faster shipping?

Are you Canadian based?

He isn't doubling the price, those prices are only for my classic boards (Common Slot, HP DL580G3 and DPS2000-BB)
The pricing for the 2880w boards can be found here:
https://bitcointalk.org/index.php?topic=893159.0

He is reselling at the exact same price you'd get from me, but you will have faster and cheaper delivery.

EDIT:  For anyone having fan problems with earlier batches of boards, please see this picture to locate the pins (underneath the plastic protective cover/urethane glue) that need to be soldered to the board:

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






Thanks J4bber for chiming in.  If you are interested in buying any other of J4bberwock's boards, http://holybitcoin.com/ is the official re-seller for the rest of his line, I will only be handling the 2880W boards.


They are PCI to PCI, hence being slightly more expensive than PCI to bare wire.  These use high quality connectors, I've used them up to I believe 260W per cable with zero problems over extended periods of time. They are rated to over 300W.

I figured I was missing something. Thanks for clarifying

I have many more PSU's in stock now.  Also picked up a couple 40A PDU's. Very heavy duty!
Will give discounts for bulk orders (same price as J4bberwock offers) with very quick shipping from Canada. Can also offer bulk pricing on cables.

Power savings from switching:

80+ Bronze:    10.5% energy savings at 50% load, 12.3% savings at 100% load.
80+ Silver:      5.6%  energy savings at 50% load, 7.0%  savings at 100% load.
80+ Gold:        2.2%  energy savings at 50% load, 3.4% savings at 100% load.

All when used on 240V outlets.

Is there anyone UK based doing this?

NICE

I'm based in France, so I'm handling all european orders directly.
Since the first batch is sold out, I'll probably won't take orders until mid-march.

Starting to get low on 24" cables, will be getting more shortly.  Expecting more of J4bber's 36" cables by late this week, early the following. The guy is a work-a-holic and still can't keep up with demand!

Take my money!!

http://weknowmemes.com/wp-content/uploads/2012/03/shut-up-and-give-me-your-money.jpg

 ;D

PM'd back

and pm'd you back. hook me up :D

Too bad these are 220W.  :'(

Just convince your significant other that drying clothes by air is way more eco-conscious! Then start burning 30A of 240V 24/7 on increasingly difficult mathematical algorithms. :)

I am currently sold out of PCI-e cables, I am expecting more within 7-10 days, both J4bberwock's high quality >16awg 36" cables and the standard 16awg 24" cables.  Will update when they arrive.

You can use the dryer outlet or the stove outlet if you are not using those currently.

110V-120V is just not enough to run large PSU's, the required amperage would be crazy.

^  As my reference to air-drying clothes :)

Problem is the 220v is in the 2nd floor washer&dryer alcove between kids' and guest bedrooms. Lol. Too loud probably. Lol

I have J4bberwock's custom 36" cables arriving on Wednesday.  Hoping to see the 24" cables this week as well.

just telll them it's one of those sleep machines that make noise for them to sleep to.... LOL

I've got 3 new 220v 30a lines being installed today.  Might have to look at trying one or three out when you solve the fan noise issue.

Currently working on it.

http://imgur.com/a/VrL81#0

good idea - the only reason the fans were on the end was to address space requirements.


and you can get your dremel took out and cut the end off also.

how many cables will you have in stock ?

The order of 24" PCI cables has just shipped, I don't have an estimate yet but I imagine it will be a week or so from overseas. J4bberwock's 36" PCI cables are due to arrive on Wednesday, but I will be away until Thursday. How many are you after? I will have hundreds of the 24", and about 200 of J4bberwock's 36".

well i need 2 2800 PSU's two break out boards and enough PCIE 24 or 36 cables for both PSU's

also need two power cables

when can you ship ?

PM'd

Forgive my ignorance, but how does one place an order? Do you have a website?

Scotty, PM'd.

Ordering can be arranged via PM for now, might try to get a website together one of these days.

Hi Finksy,

I'd like to give one of these a try to see if replacing my DPS2000 setups makes sense going forward.

I'd like:

1x PSU
1x Breakout board
12x high quality 36" copper cables

I'm going to give it a good beating by powering 3x SP20E @ 1.5Th/s per unit. Each unit pulls about 950w DC from a PSU at that speed. May also give 2x S4s a try.

Please PM me at your earliest convenience.

PM'd Prelude.

I have J4bberwock's cables in stock for now, expecting more of the 24" PCI cables by the end of next week.

Just how loud are these PSUs with the stock fans?  Are they worse than the Dell 750?

The answer is yes  :) The fans they used are not conducive to cooling such a long chamber, and the restrictions inside make it even worse, so they used 3 small, very High RPM fans that put out more noise than an SP20 at 100% fan. They do this in the sake of being modular, and fitting certain space requirements in an environment where noise is not an issue.  It will not actually take much CFM to cool the inside when the air is directed from the top, and has less resistance to exhaust.

J4bberwock has a solution he's testing right now, and I've got some ideas still in the works.  Will update with either project when we know for sure.

Hey man just sent payment for two of your PSU's 2 breakout boards and 20 pcie cables alonge with the cables for the PSU'scheck PM for tx

hey Finsky or J4bberwock what sort of results are you getting so far? i had 2 Noctua NF-A14 industrialPPC 3000 PWM 140mm fans i had laying around i was thinking of using them on this... i live in florida so i overkill all my cooling. also i'm a little electrically dysfunctional, how do i go from a nema 14-50r (my stove lol) to what appears to be a c20 plug? i assume this will require 2 pieces that should likely lock together in the middle judging by the power amount?

I want to drop a note here commenting on these boards, the PSUs, the noise, along with my experiences with Finsky and Jabber.

The boards:
I received some of the first Finsky had I believe, Finsky can comment if he wishes on my versions relative to the vintage. I followed the instructions Jabber posted as a reference, but it is very simple and straight forward to hook up.
You do not need to be experienced with server power units, an electrical engineer, or even really electrically knowledgeable to put this together. You slide it on the end and use the small plastic 'pegs' to secure it. Once it is in place it is very solid. Common sense is truly all that is needed, but following simple instructions is advised if this is your first time.
I always tell everyone to be safe! Never take shortcuts, and never do things with the main power turned on, turn it off, but this is more about quality. It is there, and from talking with another home miner who purchased several more of these the next shipment was even better quality. So from a standpoint of getting what you pay for, this product stands up, and I should have already purchased more. I will be buying more and only hope they are still available :)

The PSU and noise:
It seems I am a minority regarding the noise because I enjoy the noise from all of my miners and PSUs, now the small fans on this 2880 are louder than my SP20s combined. No question about it, and no one has tried to hide it. I was told up front these babies are loud, and they are. I haven't ran any DB tests, but again, I have one unit powering 3 SP20s and the whole setup stays cool even when my ambients were rising. Today I am moving two of the 2880s to my bedroom which is where I like to keep the things I tinker with the most so I may keep a close eye on them. These have been running in my kitchen where I temporarily borrowed the 240 from the oven and stove (two separate lines on a 50 AMP breaker). I currently have two S4s, two SP20s, and a good bit of S3's I sleep with and know full well the 2880s will be the loudest. Without modifications they will be the loudest in your farm.
They are also the best power supplies I have worked with by far. The first one has run non-stop for about 6 weeks. I have driven it to 3150 watts clocking my SP20s as high as they could go. I think the 2880 would have gone higher, but I dropped the SP20s back from a pure power usage standpoint. If you want a total package power supply, use this setup. Top rated gear imo and I have a variety of server and standard ATX PSUs under my belt. Not only from mining but years in the Industrial PC and CNC controller industry.
This PSU with this breakout board is a beast in every aspect. The only thing I haven't bugged these guys with yet is running them in a redundant setup as I truly want a 55% load redundant setup with usage monitoring. I haven't bugged them because I haven't gotten to that point.
If you are disappointed for any reason it will not be the board in my experience.

The guys:
Fisnky and I chatted quite a bit during the purchase and after. He will do anything he can to make sure you are not only pleased, but he keeps you abreast of anything which may come up. He shot me a note to have me check specific items, he questioned my input power, and plainly wanted to make sure everything went smooth no matter what. Finsky obviously understands what customer service is, which is missing from many in our community. He did not want a problem to arise for any reason, be it my fault for incoming power, placement, noise, etc, or anything from the supply end. He is up front, and offered escrow of my choosing, and other ways for my security. In the end I simply sent him the coin because I felt there would not be an issue. IT wasn't over the top, fake, kind of salesmanship ala used car guy, it was genuine he wanted to put that product in my hands and help me make it function without delay.

Jabber is a busy guy, and I know he is involved in designing many projects. I did my legwork and read back, talked to a few folks, and I never found anyone who was not pleased with their deals. If you simply want to purchase the board talk to Finsky, there isn't a reason to bug Jabber if you are in North America. As you can see from their posts regarding the alternate fan placement they will continue to build on current projects. While some of us may want more from the current design, more of us wanted the board to run the 2880 in our hands as fast as possible. I have no doubt Jabber will entertain future revisions with different functionality but keep in mind he also has minimum quantities, and putting the initial designs, production runs, etc is not cheap. Neither of these guys should be losing money to make one-off designs, if you want something there is nothing wrong with asking, but be somewhat knowledgeable and understanding regarding your request and the response. I have respect for both of these gentlemen and as I mentioned, I have plans in place to purchase more products in the near future.

I apologize for the wall of text but I wanted to convey my positive experiences.
If you have a need to power a few miners, a couple of S4s, a few SP20s, or a lot of S3s or S5s, this is the unit and board for you. I have a friend who received cables as well (these were not ready when I placed my order) and he has the same comments and experiences I have relayed here. I call it the Total Package 2880 because it has become my go to power supply. Do not get me wrong, I have several other server power supplys of the 2000bb variety running happily, but when it comes to density, power usage, and counting pennies this unit makes the most sense today and for what I see next gen. SPtech have already told everyone their next gen miners will be big boys and made for industrial miners. No word on if they will include power units, and we know BITMAIN cannot provide a proper power supply.

I know what I have with my 2880s and these boards and I am very pleased. Going into the unknown next gen I have no doubts my 2880s will be able to handle whatever is thrown my way and that cannot be said for the average ATX powering the current gen. If you are going to purchase a power supply, you do not get what you pay for with retail ATX units, the pricing structure is ridiculous imo. I consider paying for one of these packages is currently the best way to go for a multi-miner setup today, and probably a single miner soon. Do your homework on pricing. People say the ATX variety are easier to sell later, but IF I decided to sell a miner with a power supply I would not include my 2880 and breakout board. It would be something smaller for that particular miner, and if it is a larger quantity sale then the customer should be advised that the 2880 is the way to go for that type of setup. Otherwise I am not doing that person justice in my opinion. You would have a hard time getting these out of my hands anyway. It would be much cheaper for you to order from Finsky haha because I love these units.

Thanks Finsky and Jabber, I appreciate your product, and the service. It is refreshing in a world of daily scams and theft to meet some of the few people who are legitimate business minded people with core customer service skills that only come from sincerity and roots in true customer service..

Got it! Thanks, PM'd you back.


OVRGRO,

From what I've been able to test so far, these PSU's will hold 90+% efficiency well over their rated power.  I have no reason to doubt IBM's rating of these things at 94% at any kind of reasonable load, so I stick with that.  As far as alternate cooling fan setups, I've got some fans on order to try at differing loads, and J4bber's already got some fans being tested right now.  I'll post as soon as I hear a confirmation from him.

As far as going from a household 240V plug like the 14-50R, IMO the easiest, cleanest solution is to plug in a 40A rated PDU with C19 outlets and individual switchable breakers, like the one pictured in my OP.  You would just change the PDU plug to the same 14-50R plug, and then use C19-C20 cables to connect the PSU's to the PDU.

If you were only planning on running 1 PSU (what's the fun in that? :) ) you could just re-wire the C19 cable going to the PSU to fit the stove outlet.  For other solutions involving extension cables and splitting up the wiring to multiple outlets, you would need a junction box, and should consult an electrician. I found that buying PDU's was cheaper than all the extra wiring, junction box, outlets/plugs, etc required to run multiple legs off a 40-50A circuit, and again it is much cleaner and easier to revert back to "stock" w/ a PDU just plugged in.

sloopy,

Thank you for the kind words, it really is much appreciated. I am sorry our deal on the SP20's never worked out, hope you are able to find some more hardware to fit your need. Yes my formal day-job is in service, thankfully (or maybe not?) my customers in "real life" are generally more difficult to deal with than the folks around here. 

Someday when I get a shill account, I want it to be just like you. Lol! :)

I feel the same about the PSU's and boards as you do, and that is the only reason I got involved with J4bberwock and this project to begin with.  I won't represent something that I don't believe in, and these things are the real deal.  There really is no comparison to ATX power supplies in durability, efficiency, value, etc.  I can't believe you sleep with that kind of hardware in your room, that is crazy man! You better get some ear plugs or you are going to lose some hearing with the 2880W'ers in there.

Bump, both cables now in stock.

Hey Finksy

i would like to order  PSU, Board and a full set of pci-e cables, can you pm me a price please.

thanks

PM'd

Got my 2 PSU's breakout boards and PIC-E cables within a week of placing my order

the packaging was impecable bubble wrap on everything and even zipties for the cables !

Both PSU's work one thing though I have hardware that seemed to require an 8pin PCI-E male input

so i ordered these :


http://www.ebay.com/itm/1pc-6-Pin-PCI-E-Female-to-8-Pin-EPS-Male-Power-Cable-Adapter-for-PC/251573913677?_trksid=p3693.c100102.m2452&_trkparms=ao%3D1%26asc%3D20140212121249%26meid%3D655ac8d6e56b4e73aca3db9c18f64f8d%26pid%3D100102%26
 (http://www.ebay.com/itm/1pc-6-Pin-PCI-E-Female-to-8-Pin-EPS-Male-Power-Cable-Adapter-for-PC/251573913677?_trksid=p3693.c100102.m2452&_trkparms=ao%3D1%26asc%3D20140212121249%26meid%3D655ac8d6e56b4e73aca3db9c18f64f8d%26pid%3D100102%26)

hooked them up and they MELTED !! my fire alarm went off , I mean this happend the seccond i turned on the PSU's

So i tried just using The six pin 36" PCI-E cables that Finsky sent me in the 8 pin slots and it worked withoute the adapter : which probbaly means those last two are just ground or something.

I will never order cables or adapters from China via Ebay again!!

I plan to order more of those PSU's and cables once i figure out how to replace the PSU of an S4 with one of these.

Thanks Man

You are right regarding the extra pins on 8 pins PCI-E, they are simply ground, so they don't allow for higher amps.
The power still flow through 3 yellow cables.
And the 8 pins PCI-E cables in NOT the same as the EPS one you linked. on EPS, you have 4 yellow (+12v) and 4 black (ground) wires instead of 3 and 5.
Plus the ground next to the latch on the PCI-E, where on the EPS, the +12V is next to the latch.

Even if it looks easy, and unless you are absolutely sure of what you are doing, please take the time to ask when the breakout board/cables won't go straight in the miner.
Custom cables can be made upon request, and sometimes, like in your case, they aren't necessary.

You were lucky, you could also have burnt your miner.

Some chinese manufacturers don't care about the real quality of the cables they are selling for one reason:
PCI-E cable is supposed to be used on a GPU drawing 75w for 6 pins and 150w for 8 pins
So, even with their crappy thin cables like 20 AWG, you should be safe for a GPU, but miners manufacturers are pushing the connectors (and other parts) to the limits to save a few cents.
That's the reason why we can see some miners drawing up to 250 or 300w from a single 6 pins PCI-E plug, and the manufacturer asks you to use 16 AWG or better wires with 45750 series crimp pins.

BTW, what is the hardware requiring the 8 pins connectors?

Regarding the S4, I'll have a look since I got a few parts from one, and I want to play with them.

Yes I really count myself lucky that i did not blow one or all the boards in my scrypt miner

the miner in question is in my review post

https://litecointalk.org/index.php?topic=24945.0 (https://litecointalk.org/index.php?topic=24945.0)

if you look at the pictures you can see the power hookups.  I has eight boards which all pull around 250-280 watts from each 8 or 6 pin connector.  Your Connecters are even better than stock connectors the ones that you see in the picture would somtimes get warm at full load.  Yours stay cool  :) :) :)

thanks for the further info regarding the cable specs, I can imagine those crap cables i bough blowing up the miner or a GPU and then setting my house on fire.  It was a waste of $75 but live an learn maybe the plastic connectors could be of some use to you ?

I have 30 of them since i won't be using those adappters anytime soon.

If you could make something modular for the s4  that would be awesome as well !!

thanks again for the great cables.

If you get them to work well with an S4 with screws instead of PCI-e, take some pictures and write step-by-step instructions (what adapter needed, what wire to cut, etc.), I am interested.

Thanks!

Thank you for the kind words Marvell, let me know if I can help you with anything or you need more in the future.

I think I'm going to look into a plug & play solution for the S4's, it seems more and more are making their way into the hands of home miners, and as we all know they came with SHIT psu's (par for the course for BMT lately it seems).  Obviously the PSU won't fit into the form factor, but if arranged right you could power 2x S4's with one 2880W PSU. I have a couple S4's right now, so I'll take some measurements and get something made up to work with the IBM 2880W.

Also, to add to what J4bberwock was saying, what you end up with as for either model of PCI-e cable used with this breakout board is better quality than nearly any cable that comes shipped with ATX PSU's. These are purpose-built for handling heavy loads as required by any crypto currency miner, unlike off-the-shelf ATX PSU's. I'd say you were very fortunate Marvell that no damage appears to have been done.  And yes, J4bber's cables are pretty badass XD

After a few minutes looking at it, the hardest part of the job will be to fit the PSU inside the case (quite difficult since the case is 13cm high, and the PSU in its side is 20cm...)
If you put it outside of the case to power 2 ant S4, you'll be fine, and adapter cables will be easy to make.
Splice 3x ground soldered together to the appropriate gauge or directly crimped to the correct connector, and do the same with the +12v ones.

You can also simply solder the PCI-E plugs where they are missing on the hashing boards if you have the boards with screws instead of PCI-E plugs.

I am out of stock of C19-C20 cables until mid-late this week.  I also have J4bber sending me more boards and purty 36" cables sometime next week. Price of 36" cables might be going up for next batch received.

I will be in the GTA this weekend (leaving tonight), if anyone in the area needs PSU's, boards, cables or anything of the like, let me know and I can bring them when I leave this evening.

Update:  I am currently out of PSU's.  If anyone would like to order boards, cables, etc and source their own PSU's, PM me.  I have more on order, and will update the post as soon as they arrive.

I bought 3 boards, will make a review when I get it.


 ;D ;D ;D ;D

Noooooooooooooooooo, i was waiting for the c19 cable and now no psu.
when you receive the PSU's i'll order one right away.

thanks

Will update when PSU's arrive.

Here is a thread on adapting IBM 2880W breakout boards to replace PSU's in 2x Antminer S4's: https://bitcointalk.org/index.php?topic=1036295

If I get some time, I will make up some harnesses to sell myself.  I'm a little busy for the next week or more, so if anyone wants to do it themselves, all the measurements are there.

Just a heads up, I will be away until next Wednesday, and likely will not be able to answer messages.  If I can I will PM everyone back as soon as possible. 

i would like to buy 2 breakout boards and 16 of the 24" cables
can you pm me with a price
thanks

PM'd

Still no PSU yet. ?

Hi!

Does this PSU works at 220Volt in 2 phases?

As far as I'm aware, Two-phase power is not in popular existence anymore.  If you are referring to standard single phase (using 2x 120V legs off a breaker panel to get your 240V) then yes, that is what is required for these.

As far as three-phase power, I am not 100% sure whether these (or any popular server or ATX PSU's) are designed to operate on typical 208V 3-phase power.  PhillipMA had created a thread about using 3-phase power with a PSU, and I believe he was planning on using 2 out of the 3 hots along with a ground to create a compatible Single-phase power solution, but I do not know where he is at in his testing.  I have a customer who is planning on using these PSU's with 3-phase power in Ontario, but again I cannot confirm whether or not these will work directly with standard 3-phase power.

As for my PSU stock, they should be shipping tomorrow, and I will be picking them up within the next week (hopefully), but I still do not have confirmation on dates.  Will update as soon as I know for certain.

Not exactly, you were pretty close at the end there. It's a pretty misunderstood topic, and since most things outside a few very specific niches just "handle" any voltage difference it's rare that anybody nowadays needs to know. But, for the record, in the US at least the homes are supplied with a single 240VAC feed which is "split phase" meaning it exists between two phases or "waves" of AC current, one is -120VAC and the other is +120VAC. These  are in fact split in to two legs when they're fed from the mains in to your breaker box, you can see evidence if you ever take the cover off your box and notice each breaker alternates feed lines. Anyway, without falling down too much of a rabbit whole (sorry AC is a bit out of my wheel house, I much prefer low voltage DC) the 240VAC line that is available in all american homes (I believe it's required by law? or mandate? Hell I have no idea) rests in between two 120VAC waves. This is often referred to as dual phase 240V power.

So it stands to reason that you could win an easy bar-bet by asking the simple question "what voltage does the electric company provide to your home in the US". My assumption until it was explained to me by someone far more intelligent was 120 volts is 120 volts, none of this voodoo wave crap.


So 440V? Or do you mean split phase 220V? Not to be confusing but I do know some of my customers have in Mexico and elsewhere have a single feed of 440 at there factories or industrial areas, or at the very least it's the only reliable power source. If you mean 2 phases of 110V then yes this will work with split-phase 220V. It's confusing, it's convoluted, I feel like I'm pretty spot-on in guessing you mean dual phase 220, or split-phase, and not two separate phases... if you do mean two seperate phases then it's an easy fix, I believe you can just disconnect one of the wires, but don't quote me on that and I almost regret saying that already!

Good news, PSU's have FINALLY shipped today, hope to see them shortly.  What a cluster-fuck that was...  All I can say is supply of these PSU's is getting lower, we are somewhat drying up the used PSU supply for North America. Go miners! :)

How many did you order?

40

For anyone needing large orders in the US (5 or more), I can have PSU's drop-shipped to them as well to save quite a bit on shipping, I just won't be able to test them ahead of time.

Woot, don't forget to put 2 aside for me  :)

Alright, PSU's arrived today. I'll be sending PM's out right after this, and prices have been updated on the first page. I'm afraid the next batch of PSU's will likely continue to increase in price, as it seems the used PSU market is not infinite.  I have had all my 36" cables reserved, but will have more as soon as I can get some from J4bberwock.  Thank you everyone for your patience.

Finksy

P.S. If I missed anyone with a PM who were interested before, sorry please PM me again.

Many PSU's shipped out today.  Thanks everyone for your patience on getting more of these in, still plenty left.  After pricing some units drop-shipped to a US customer, I'm afraid next time I order these there may be another price increase :( Keep your eyes on e-bay for cheapies!

Finks

P.S. will have more 36" cables shipped by the end of the week, should have them mid-late next week.

Can take orders for PSU's with 36" cables again.  They are scheduled to arrive early-mid next week.

If anyone who has purchased from me is willing to, I would greatly appreciate trust being left.  I have had quite a few successful sales, and like to think that I provide good service to my customers.  Any problems are dealt with accordingly, and I would like to build some positive trust to prevent any wrong-doers from dragging it down.  Thanks,

Finksy

Trust left. :) Sorry I forgot to leave it when I should have!

Side note, might need some more hardware soon. Will drop you a line!

Finksy will have something for you in the batch he'll receive on wednesday, so it might be a perfect timing.

Do you have a C19 to C13 adapter for these? Or a C19 to 240V outlet cable?

I only have C19-C20 cables.  I don't recommend using C13 adapters, as I don't believe the C13 receptacles themselves are even rated to run at the required AC current in steady state (14 or more amps).  As mentioned in PM, what I do for wiring up individual PSU's is to cut the C20 end off, and wire on a replaceable 20A 240v 6-20 NEMA plug:
http://s14.postimg.org/gvetqpc2p/6_20plug.jpg
and use the appropriate receptacle/wiring. For multiple PSU's, wire large individual 50A power circuits for a PDU, and connect each PSU/breakout board to the PDU.

I was about to buy one of these but want to confirm here whether these will run on American 240v (which is +120v hot, -120v hot, and ground). Most modern psu can take almost anything but since this is a dedicated server 240 psu I just want to confirm it does not require a +240v hot, neutral, and ground connection.

Yes, these run on 240V SINGLE PHASE power (also referred to as split phase, 2x 120V hots + 1 ground as is typical in North America). I have not tried these on 3-phase 208V power, though the label does not specify, it only states 200-240 V 50/60hz.

for a psu the breaking board is used to connect the psu and replace a computer motherboard? is that for that purpose? have connected a psu to a computer motherboard to switch it on...
mining giving less than electricity bill
IS there a way to reduce electricity bill of a psu ? can breaking boards be purchased anywhere on the web and plugged in to a psu? Does it give better efficiency for costs?

Thanks to reply

Holy Crap Buddy, do a bit a research before asking all these irrelevant questions.

These Breaker Board are only for this PSU, look at the pictures at the begginning of this post.

reduce electricity, get a better rated PSU, GOLD or above.

Use the paper clip trick to power on the PSU, no need to plug a motherboard in it.

different breakerboards for different SERVER PSU can be purchased from other peoples.

How Many Watts per hours. go look in the S3 Threads.

How Many S3 for this PSU, do some maths. 2880 / 330

but don't expect to just plug this PSU in your outlet, you need 240V

He posted the same thing in my thread, I get the feeling that English isn't his first language and he's never seen supplies like these before.

Finksy, pm'd you

Replied.

I'm out of town until Monday, so communication is a bit spotty. Have more packages arriving from J4bber on Monday-Tuesday, and will have everything in stock.

Have everything ready to go, shipping will take up to 48 hours right now due to work constraints IRL. 

Get your supplies wired up in time for Sfards or the Antminer S7 release, coming this summer!  Currently working on getting 24" cables for cheaper.

Hi:

Is it possible to solder the cables directly to this kind of PSU with out the need for breakout board like other lower server PSU ?

thank you.

I put in bold letters the advice from the only guy that did it to my knowledge.

Thank you J4bberwock for good advice , i know there will be a lot of work involved to harness the connector.

 but what it take my attention is this line:


Is the high watts drawing by the PSU is a result for the harness connection?

If yes, what the power drawing when we use your breakout board on full load?

Thank you.

I have personally taken the PSU's up to 13.4 amps (3200 watts) With 3x SP20's for a span of two weeks or so. Held up just fine, I imagine soab's run up to 3785 W was fairly temporary, I feel like the thermal cutoff would have kicked in if run for extended periods of time.

Finksy, pm'd you

Finksy,

PM'd you. sorry for the double message.

-Newtry

Out of town un-expectedly for a few days, limited access to internet/BitcoinTalk.  Will PM everyone as soon as I can w/ info requested.  Thanks,

Finksy

Back in town, all messages should be replied to.  If I missed anything from anyone, please PM me again.

Bump it up

Bump

Will this break out board work for the IBM 39Y7408 Bladecenter H 2900W as well? Or is it limited only to the 39Y7349 Model?

it works for any bladecenter H PSU.
BTW, some sellers are rounding the 2880w to 2900w, your P/N 39Y7408 gives 2880w for me.

Great, just wanted to make sure before I pm'ed Finsky with my order. Thanks J4bberwock.

Just an FYI, I will be out of town from now until after the weekend, and may not be able to respond to PM's. 

Great Mod and fantastic Power supply.
Here is how I have mine deployed.
First Rig 3 Antminer C1's, Second Rig 8 S3's, and the third rig is powering 2 S2's + 2 S3's.
Loud Yes but I'm working on a fix for that.
Recycle-Reuse-Repurpose and mine away!

Thanks Zero

All PM's should have been replied to now.  Back in the swing of things, orders shipping out today.

The original post indicates that these require 240 volts. But the label indicates 200 - 240v.

So these will work on 208 volts, right? That's a pretty common data center voltage option.

Yes they will work fine, I have run a pile of them like that..

Finksy,
I PM'd you for an order.

Can someone tell me the physical dimensions of this power supply?

Edit: Finksy answered me via PM. The approximate physical dimensions with board attached are ~23" x 10" x 3".

Edit: Also, does it really weigh 45 pounds?
Answering my own question, no, it's only 15 pounds. I just missed that in the original post. In his PM, Finksy said they're approximately 14 pounds.

I've made a few attempts to search for this info, but most of the hits are people selling them.

Thanks in advance.

can i purchase 1 from sweden? ??? ??? ::) ::) ::)

Contact J4bberwock, he's in EU and can sell to Sweden:  https://bitcointalk.org/index.php?action=profile;u=206446


Just to update, the actual dimensions are 19"x 8" x 2.5" (17" length w/out board attached), and weigh around 5kg w/ fan packs (11Lbs). I was a little over-zealous with my estimations that night :/

Hey Finsky

Do you still have some PSU and board in stock. ?

IF so, PM me a Quote for
1 PSU
1 Breakout Board
24 x 36" inch wires
1 c19 Cable

You should still have my coordonates from my previous orders


Kaltar

I'm trying to figure out how I would deploy these in my rack, hopefully reusing some of the shelves.

Is it ok to stack two of these PSUs? Seems like that should be fine if the cases don't get very warm.

Which end is the hot end and which is the cold? If these were originally plugged into server cases with the fans on the front, then maybe the fans pull cold air in rather than exhaust warm air out.

I've run them stacked but stopped since the hot end was getting a bit too hot for my liking due to one side being restricted.

The cold end is the end with the fan pack.

Thanks for the info. It helps me plan. I don't have the PSUs in hand yet.

When you says that the hot end was too hot due to restriction, was that an air flow problem your particular installation? Or maybe you're referring to the breakout board restricting the exhaust?

In my case these would be at a data center, so the input air will be pretty cold (about 21 degrees C). So maybe I'll be OK stacking them. I can double check with an infrared thermometer.

In my experience running 2 stacked PSU's was fine, so long as the hot end (break-out board side) isn't restricted on the bottom.  I.E. if you are running on a solid flat shelf/rack, the breakout board over-extends the edge to limit exhaust restriction.  Also, these PSU's come with a very good thermal shut-off, which I have had some PSU's hit on a nearly daily basis at certain times in the summer with lack of ventilation/AC. They come back online every time without a problem (50+ times), so running them hot IME is not a problem, they shut off before any major damage is typically done.  How hot you want to let the breakout boards get (in a multiple PSU-stacked configuration) on the other hand is another question, since the exhaust air can get to 100+ degrees.

Kaltar, I am currently out of stock on boards, and am in the process of working with J4bberwock to shift some of the board production here to Canada to save on time, VAT and shipping expenses.  I'm looking at about a 2-3 week down-time, but when I am setup with the materials here on hand, I should be able to reduce the cost of the boards as well as keep more stock.  I will keep this thread updated!

That is great practical info! Thanks for the additional details.

In my case, I'm planning on reusing a beefy partial shelf that held a RAID array that we no longer use. It can handle at least 30 pounds, and is only about 14" deep, so two stacked 2880 PSUs will comfortably hang over the edge with the breakout board side in mid air without obstruction.

Sounds like this will work great. Thanks again for the useful details.

I want 1 Breaking board + 20 cables (standard version).

Let me know when you have some in stock.

Hi Finsky,

Can I please order:
2x PSU
2x Board
32x 24" standard 16 AWG cables

Thank you.

UPDATE:

Finally, I have received most of the components and started soldering and assembling boards.  I am still missing many of the nylon spacers, but once they arrive I will have boards ready for shipment.  I have gone back through my PM's to notify anyone, if I missed anyone or anyone else is interested in a quote please PM me. I will be accepting orders, and they will ship out in the order they are paid for. I'll be producing around 40 per week, so it will still take some time to fill all the orders.  I hope to have all orders shipped out before the S7's ship.  Thank you everyone for your patience.

Finksy, I'd like to order the 2880W breakout boards.  I've tried to PM but since I'm a nube, features are blocked.  How do I proceed?

-JAAUDIO

All my orders are handled by PM.  I will send you one with some information.

Still waiting on the board spacers to finish assembly, I think they hired someone to swim them across the ocean  >:(

Any luck receiving the spacers?  The S7's started shipping today.

Still have not received the spacers, and tracking # is not updating.  I have re-ordered from another company with FedEx express shipping from the US, one of the packages should arrive shortly, and I will ship boards on the same day.  I apologize for the delay, and will have compensation for those that have pre-paid and had delayed shipments.

First 16 boards of this batch have shipped out. Now filling an order of 90, then will have stock for orders. I am looking at about 1.5 weeks to finish this current order off, anyone who's interested in ordering can PM me, orders will ship out in the order they are paid for.

I have also added packages to the first page to make ordering easier.  Shipping will still be calculated individually, and price breaks can be had on large orders ($2,000+).

Was any progress made with replacing the fans with something a little more quiet ?

I did see some posts that people were working on it but nothing conclusive as yet ?

cheers and apologies if im just being blind

i want to buy The "Get Me Going" Package - $155
please calculate it, ship to yogyakarta, indonesia
i'l use bitcoin.

Can somebody tell me which is the bridge that I have to make in the PSU pins to AutoPower On?

OK Finsky.

BTW thanks for the PSU Works great now.

i got a question you or someone else might be able to answer, i got this nice IP Power Stitch with scripting and auto ping etc that i want to use to rereboot my miners when they become offline. of course i can't plug the IBMs PSU in them cause 1. the power is 240V and the switch is 110. and 2. even if could it`s only 15amp. BUT what if i plugged a small 12v Power adapter to power a relay switch that will be triggered to on when power applied to it, and connect that instead of the on off switch on the breaker board of the IBM PSU.

this way i could reboot all my miners remotely or un attented. but i got no idead of the parts i would need for the "relay" or if that even is the proper word for it. let me know what you think. or any one else.
time is a factor cause i`m going on vacation next week for 2 weeks.

heck this could be even applied to regular PSU bridging the green and black wire to power them on.

Kaltar

Fair approach given what you have, it should work.. In the case of the breakout boards, to the left of the switch they have two contacts, you can use those also to power on and off the board.. That should give you an easier option than playing with the switch itself..

OK, tonight i will go to the electronic store and try to explain to the person what i want and hope he understands what i mean, and thank for the info on the contact point, it will make it easier.

Anyone able to get ahold of finsky? Not replying to any pms

Had a very busy last week.  Replying to PM's now.  Will be able to ship from stock starting late this week or early next.

I was wondering if you could make me up a custom set up - I essentially need the Pimp Daddy x2 - aka "Super Pimp Daddy".  I am good on the C19 cables.
Thanks

Did you crack the nut on the PSU connector shortage J4bber has keeping him making more boards for the next couple of months?

All the boards that I send out are tested for failures before shipping, thank you.

Edit: I'm an idiot.  I thought you were referring to electrical shorting, in which I had 1 happen due to sloppy soldering  :-\

Absolutely, PM'ing you now.

waiting on the Super Pimp Daddy Price --  ;)

Sorry kilo, price coming your way.  8)

The 3 pins connector that goes in the PSU will be available mid December, if I remember correctly. 15 weeks delay or something like that...
Finksy still have a fair amount of them in hands, and most of my remaining stock have been reserved by "you know who".
I'll also have the 4kw breakout board ready in a few days and first deliveries this month to compensate, if we really end up short of 2880w boards.

Thanks J4bberwock,

I am finalizing a large order for a customer and will have boards and packages in stock as of late next week ready to ship out, shipping takes 4-5 business days anywhere in North America.  I will be drop-shipping PSU's for orders to the US to save on shipping and any potential customs issues from now on.  For us Canucks, I will have many PSU's in stock in about a month, but can still supply boards/cables in the meantime.

I can also take large orders still, as I have a reasonable stock of all the components still.

Sweet, do you have a page with the price and available stuff that you have or will have? I'm interested in 16/18Pins long cable for S5/S7 and mayyybe PSU if they have same clean power and quiet as EVGA G2/GS's.

I will be out of town until Wednesday, in a low/no reception area.  I likely will not be able to reply to PM's until I return.  Thanks

How do I order the The "Get Me Going" Package?

PM's are being replied to as we speak

Finsky,

Will you be getting S5+/S7 specific breakout boards J4bberwock is working on? If so, I would like to get one with all options.

Yes, I will be producing the IBM 4K boards.  Still waiting on components, and J4bberwock is finalizing his design for the PCB.  I will be minimum 1 week behind his initial batch, but will have some produced as soon as I can as well for small orders in North America.

Please put me down for your batch 1 list for 2 kits, would like all options under and over volt option, volt meter etc.

Will you be selling the DPS2000BB PSUs along with the board and optional components?

Yes, I will carry some stock of DPS-2000's here in Canada and will have US orders drop-shipped to save on shipping and tax/duty from the border.  The supplier that was supposed to have the power connectors in stock (that were already paid for) just emailed me back stating that "in stock" just turned into "6-8 week lead time from manufacturer".  >:(  I will be scrambling to get them in as soon as possible for these.  J4bberwock offered to send me some, but he has enough orders to fill for himself so I'll see what I can find.

IBM 2880W boards are shipping from stock, tracking within 48 hours, and typically 4-5 business days anywhere US/Canada!

Packages are suspended ATM waiting on C19 & 24" cables, though I have many of the 36" cables in stock.

https://bitcointalk.org/index.php?topic=1238511.0

S5/S7 data cables are finally here with pricing.  If I miss anyone by PM who has expressed interest please send me a msg again.  Thanks!

i am currently out of 24" PCIe cables.  Will have more in stock in approx 1 week.  If anyone wants a package with 36" cables substituted for the shorter ones, PM me and I will work you out a price difference and ship within 48 hours.

Hello,
The Power supply, If I am reading correctly is US 220 Volts.
The C19 and C20 Cables don't look like the US 220 Outlet.
I understand the end that goes to the Power supply, the outlet end.

What am I missing?????

Thanks

Daplayer,

The C19 end of the cable is required to feed AC voltage into the PSU via the breakout board.  I supply C19-C20 cables with some of the packages because it is the most commonly available cable, and ideally you would power these PSU's through a PDU, which has C19 outlets and it is a plug & play affair (just like the "Pimp DaddY" package).  What many people including myself will do for powering a single PSU is cut off the C20 end of the cable, and wire on a NEMA 6-20P and corresponding receptacle.  These parts are commonly available at any hardware store, and are safely suited for the maximum draw of this PSU (I've tested upwards of 13.5A draw). 

As usual, you should consult a certified electrician for your isntallation.

Exactly,
That is what I was missing.

I totally get what you are saying...

Thanks For your Time.

DaPlayer.

Daplayer, no problem!

record364, te he enviado un PM.  :)

Curious if you ever got the 4000w package and what the cost would be for the PSU, breakout board, side plate and fans would be if you have them.  The noise of the 2880w are starting to get to me.

PCB's are currently being manufactured, I expect to see them in about 10 days or so.  Side plates are being protoyped right now with a forum member, we are just trying to figure out the best material for price, weight, and durability.

I'm interested in either x1 Bladecenter H 2880w breakout board, or the DPS-2000BB for the 4000w setup. I would like to purchase 10 cables initially to power an S7. I also sent a PM as well.

Thanks!

PM replied.  Everything currently in stock and shipping typically within 48 hours.  No firm ETA on the IBM 4K boards, I expect to have them for sale within 2 weeks.

I am potentially sitting on a large order of PSU's that will take up availability for the coming couple weeks or more.  All orders that have been placed thus far are fine, but future orders could have a significant delay for PSU's.

Have packages to ship from stock.  I added another package specifically for 2x Antminer S7's called the Double A, due to demand for this specific package.  I think it provides quite a lot of value compared to all other alternatives on the market, including the Bitmain PSU's.

PMed you

Thanks Finksy

Hello,

Is this package still available?

The "Double A (Antminer/Avalon)" Package - $190
Enough to power 2x Antminer S7's for as cheap as possible
 - 1x 2880W PSU
 - 1x Breakout board
 - 20x 24" PCIe cables
 - 1x C19 cable (specify C19-C20 or C19-NEMA 5-15P)

Would want C19-C20 cable and a C19-Nema 5-15P cable

PM'd

sent a PM on the big daddy package  :)

Back at ya!

Do you have the 4000 watter ?



https://bitcointalk.org/index.php?topic=1178099.msg12401250#msg12401250


I am thinking of using this with 2 s-7's and an avalon 6  so we are talking


1200 + 1200 + 1000 = 3400 watts


or with an under clock

s-7        S-7     a-6      a-6
1150 + 1150 + 900 + 900 = 4000 watts.

What kind of plugs are on your PDU's?

Not yet Phil, I should be receiving the PCB's to start assembling the boards by the end of this week I hope.  I know there is a lot of interest in it, and I have quite a bit tied up in materials for it so I am as anxious as you to have them available.


4x C19 plugs, each with 15A breakers and a 50A main.  I can source PDU's in other configurations including 3-phase if requested.

I figured the receptacles were C19 but I was wondering about the input plug for your single phase 50a pdu as there are a few types of 50a plugs.

TIA.

Right sorry, the PDU comes with an L6-50P plug: http://www.stayonline.com/detail.aspx?id=6272

HUBBELL CS8265C Got it thanks.  Can you PM me a quote for four PDU units shipped to Houston, TX?

Hello,

I have PM'd about a custom order.

I had to register here to make my request, I see it added the newbie warning.

Im sure I will be sticking around. My 6 x S7 farm is getting ready to go live  ;D

Thanks

sending pm I need cables  those 15 gauge come to mind

j4bberwock sent me a 2000 x  2 = 4000 watt break out board.

I ordered two psu's on ebay.


 I will need cables

  18    15 gauge
  12    16 gauge 

Does anyone know if its possible to change the output voltage on this 2880 psu? What about the bitmains 1600 can you change the output voltage on that PS

I believe there is a write-up about upping the voltage on Bitmain's 1600W somewhere.  As far as I know, voltage control is not possible with the 2880W PSU's, however the dual DPS-2000 that J4bberwock has developed and I should be producing this week will have voltage control as an option.

Do we have pricing on any of the dual 2000 setups yet?

Not like you can on the DPS-2000BB, however the 2880W PSU does seem to internally adjust voltage based on load to maintain a target of 12V, meaning even under a serious load the PSU will continue to deliver 12V and not dip like you see with most..

if you open bitmaintech's psu it has an internal pot that cranks up to about 12.6  I just read a review with photos of the pot.

The bitmain psu has shitty pcie cables.  and cost over 165 shipped to the usa.

finksy + j4bberwock can supply 15 gauge beast cables this will help over clock and if you have 2 avalon 6's like I do ite becomes more important since the avalon use only 4 jacks.

@ finksy  I sent a pm on ordering the 15 gauge cables.

j4bberrwock sent me a breakout baord and i have 2 2000 watt psu's from ebay coming.

I will need the 15 gauge cables I want to do a series of tests and photos that show how well they work for avalon 6's and I held onto my best s-7 I want to show how the better cables allow higher clocks.

Any update on the 2x 2000W PSU board? Sign me up for 2 boards from your initial batch.

Thanks.

DHL has delivery scheduled for today.  I will be up well into the night making boards and hope to post back with an update tomorrow.


NOTE: WALLET ADDRESS HAS BEEN CHANGED IN MY OP, AND NOW LISTED IN MY SIGNATURE. 

Great news, let us know your pricing and when to send BTC.

I will be out of town and away from service from this afternoon until mid next week.  I will have 4K boards ready for production by then, and will start a new thread for them.

Replying to PM's as quickly as I can and filling orders as they are paid.  Thanks everyone for your patience, and thank you Bitmain for shipping orders early while I'm away   :o  We'll get all those miners online in no time.

Hi, I would like to buy 7 "Royale With Cheese" Packages

Do you have everything on stock?

PM'd!

Merry Christmas everyone!

Merry Christmas to you as well,  :)

Thanks and Merry Christmas to you too  :)

36" PCIe cables back in stock

Packages now available without PSU's

IBM 4K packages and boards now available!!!!  Link: https://bitcointalk.org/index.php?topic=1308296.new#new

Either would be pretty nice. Is there a chance either of these can run on my oven outlet? I can't see anymore easily accessible way to get 240v. And then i'd need some long extension cord to bring the current to my living room window.

I never dealt with 240v before.

I don't see why these could not run off an oven outlet.  The only difference is that PSU's do not use a neutral cable (typically the white wire in a 2-hot, 1-ground, 1-neutral household appliance circuit).  Also, I definitely do not recommend running a big long extension cable across your house.  Not only is it against code, but it can be dangerous.  You would be better off having an electrician come in and move the circuit to where your miners are located, sorry.

Finksy

Best not tell them i run 50A through several industrial grade outdoor cord extension for the 120V PSU, then. *Innocent smile*

I don't live in a House so i can't have an electrician come and move around circuits.

Please note:  Pending some further testing by forum members, I have removed the 80+ platinum rating in the details.  The original post used to link to a data sheet on the 2880W that does not seem to be available anymore, and some reputable forum members have brought up concerns about the actual efficiency of these PSU's, especially our typical older revisions like the IBM PN 39y7351 and 39y7349 which were built before 80+ testing was available.  I'm hoping we can soon find out definitively where these PSU's fall as far as efficiency in comparison to other comparable 80+ units (namely the Platinum rated 2980W IBM PSU).  Also, note that the stock 3x fans used on the 2880W PSU are loud and consume quite a large amount of energy, up to 60W at full load due to the design with poor airflow through the case.  MarkAZ should soon have his solution finalized which consists of acrylic panels to replace the cover and fan pack on the 2880W PSU, with provisions to mount a single 120mm fan.  This should allow it to run quieter, use considerably less energy, and still maintain full output. I would like to thank Prelude for bringing this to everyone's attention. Our debate over the testing has been a bit heated, but I think he knows that I am not in this to deceive anybody and really do want to know the facts. I Will keep everyone updated, and thank you all for your business and support.  

Happy New Year!

Any Royal With Cheese in stock?

I am currently replying PM's (including yours), and apologize for the delay.

No packages available for sale right this moment, just waiting on more C19 and PCIe cables to arrive, looking at likely early next week.  Will post and update packages, thanks.

I will be away as of this Friday for a week, and likely unable to answer posts/PM's.  I won't be able to ship any more orders than what I have lined up by the end of the week.  I will resume taking orders when I return around February 1st.   Thanks,

Finksy

PM sent. No need of the C19, only board. I have spare Molex connectors if you dont have pcie cables in stock I'll do them myself. Thank you! :)

Replying to PM's, thank you everyone for your patience.

All PCIe cables and C19-C20 cables are back in stock.  I am working at obtaining some C19 to NEMA variations for a very reasonable price without too large a MOQ.  As soon as I can make it happen I will, PM me if you have preferences (NEMA 5-15P, 6-15P, 5-20P, 6-20P they are all built to handle the same amount of current, but have blades orientated differently to comply w/ code)

how do i go about buying these psus

Nice!  :)  I won't have to cut wires anymore.  Thanks!

nice ill deff be in for some 6-20p cables , i have all my 277v circuts wired using 6-20's so nobody can accidently plug in stuff on those lines that doesnt belong there
as the poster above has said no more cutting up cords to put the right ends on

You managed to turn the fancoolers without break board?

I can indicate that I tap pin to light source 2880

PSU's & Package prices reduced, cost has gone down a bit.  May have a source for better-priced 24" PCIe cables which will bring costs down significantly.

Please be aware!!! There is someone trying to impersonate me: https://bitcointalk.org/index.php?action=trust;u=769932

Please leave neg-rep and avoid.

Bump, packages shipping from stock. 

PM Send, interested in 2 units.

Just ran out of stock of 24" PCIe cables, more on order.  Lead time probably 2 weeks.

Hi there,

I am interested in grabbing some of the boards for the IBM 2280w blade centre PSU's

am in the market for 5 to 10, however I am based in England so who would be best to contact?

Regs

You would be best to contact J4bberwock out of the EU: https://bitcointalk.org/index.php?action=profile;u=206446

Pictures added, and prices updated to reflect cheaper supply of PSU's.  Should have 24" PCIe cables in hand by the end of next week I hope.

Nice.
How are you powering the mobo's and are you using PCI-E splitters to the GPU's?

An autopart that Finsky recommended that can run a motherboard.

http://www.amazon.com/Mini-Box-picoPSU-160-XT-Power-Mini-ITX-Supply/dp/B005TWE6B8

Yes - I'm splitting each wire coming out with a PCI 6 pin to 2 6 pin splitter.  

Thank you for the kind words rdnkjdi, I like your setup, super utilitarian but effective.  I'll keep that in mind if I run GPU's again some day, cheers.

Finksy

So all your video cards are 6 pin?  None of them have 8 pin? 

I can't speak in regards to his video cards, but the only difference between 8 and 6 pin cables is that 8-pin have 2 extra ground circuits.  They can't effectively carry any more load given the same gauge wiring than 6-pin cables.  The reason they created 8 pin vs 6 pin was for standardization, 6-pin PCIe cables were only originally rated for 75W, the 8-pin cables have wiring rated for 150W.  The 16awg 6-pin cables I personally carry are rated for well over 250W.

So, you can get away with just grounding the 2 extra pins when powering GPU's with sufficient awg 6-pin cables like mine.

Good to know.  Thanks for the info Finsky.

how much  power does the antminer s7 board give out for fans can it handle the delta fans

voltage : 12V
 
Current  : 3.9A
 
Power : 46.8W

i want to try the delta TFC1212DE

is it a bad idea?

The S7 will have no problem powering that fan from the controller board, that is a similar fan to what they come shipped with.

24" PCIe cables back in stock, packages are all up for sale.

what wire did you use to extend your GPU power cables? i guess it is modded using stranded wire?

Sent pm

Replied.

I currently do not carry 6+2 pin PCIe cables, however I am currently exploring some cheap & easy solutions to add the extra 2 ground pins.

Finksy Hi how are you... Joan and Ivan from venezuelan told me about you, that you sell many diferent models of breakboards... i am looking for the HP 1300 Breakboard... that it have 8 pci-e Ports... with they cables... May I ask if you have Stock ? could you please contact to me by Private Massage  to talk... thanks so much...!

I found these on ebay, i ordered a few just to try them out.

http://www.ebay.ca/itm/6-to-8-Pin-PCI-Express-Power-Converter-Cable-Connector-CPU-Chip-Video-Card-/141746391467?hash=item2100be49ab:g:drcAAOSwezVWxZy-

Bump, packages in stock and ready to ship!

nice where did you get the fan.. did you make it with that connector?  is that enough to cool it down?

I gotta say Finksy really comes through.  I put in a few orders and he made everything happen ASAP.  All of the boards are top notch and everything is perfect.  Thanks Finksy!!!

Do you make custom breakout boards, and/or setup my backplanes if I were to ship them to you? I've got a bunch of DPS 1200FB psu's and the backplanes that hold 4 of them, but I'm not certain on the wiring... Would be nice if someone professional such as yourself would be able to wire them up for me?

Bump! Many packages ready to ship now, have power ready for your S9!

@dance191 thank you for the kind words.  I do my best :)

@ crowetic  Sorry I do not make any custom boards, all my boards were developed by J4bberwock I simply build them and sell them for North America.   It won't be worth your time to ship PSU's to me to custom wire and ship back to you, you'd be better off finding someone local, do it yourself or source something different unfortunately.  If you're keen to try doing it yourself, the RC forums are a gold mine for how-to's and pinouts for server PSU's, I'm sure you'd find one for the DPS 1200FB.  I will warn you though, I'm not sure excatly why, but I had a large batch of DPS 1200 FBA psu's that I had bought and wired up myself to sell with some S5's, and for whatever reason I could not get them to put out less than 13.x volts.  I believe it was responsible for frying a customer's S5 due to over-volting.

hey guys, looking at getting these for my gpu miners.

Is there any chance of a breakout board that Has ATX and cpu connections on it? would rather use one psu rather then one for mobo and one for the gpus. preferable pay in BTC and live in Aus.

Cheers

J4bberwock currently has one in development, however at this time I'm not aware of any server PSU breakout boards that have provision for 24-pin connector with +5 and +3.3V or CPU power for MoBo.  You can power cards with server PSU and power risers/motherboard with lower-power ATX PSU though.

Bump, get your PSU setups in time for S9's!

Bump, S9's are power hungry.  IBM 2880W has what you need!

Psu's to feed the beasts!

Bump it up

I got a bad combo PSU/Board. What's the easiest trick to test either the PSU alone or the breaking board ? (I don't have another PSU to test ...)

thanks

Was that the 2880W board you got from me in March, or was it a set you picked up second hand? When you plug the AC power into the front of the board, does the green AC light turn on through the fan pack?

It's hard to tell me if it's the one you sold me because i bought some used also.

My hosting reported it as not working anymore (No light nothing) but he tested it one more time before he bring it back to me and it started up. I will try to figure out if it's the just switch or heat/cold. I will test it tomorrow.

Are these safe to use with GPU rigs to mine with as maybe consider to buy as the power is insane and to get anything like this on a normal PSU  is $300 to $400+ for 1600watt
. What rated are these IBM breakout units?

what about 8 pin GPU ??

Just spotted that only seeing 6 pin adaptors its o kfor 6 pin by looks but most gpus have 6 and 8 pin and didn't notice that so I would also like to know as you started their any 8 pin version?

Bump it up.  Have some very large orders coming in shortly, anyone who wants smaller batches would be wise to get them now before I get tied up for a few weeks.

Hi, i have problems with two 2900w bladecenter psu's; i don't know if they are running well. Sometimes they are turning off with no apparently reason. Somewho have any problem with them?
I bought them from eBay and then i bought the special with cheese from holybitcoin.com. Somewho have the same model?  Thanks in advance!
PS: Now they have some dust; they are stored in a wrong place...  :-[

http://i64.tinypic.com/33vopih.jpg

Running and shutting down is typical of thermal shut-off.  What miners do you have hooked up to this PSU, and what is the temperature in the hosting area?

At the beginning, an alcheminer each one and the last time one of them titan cubes; up to 2.200w with alcheminer and up to 1.400w with titan cubes; temperature could be between 25C/35C (night/day). The titans are working at 60C/70C and not hotter. Here the summer is too hot for me...  :D

Hey Finsky I sent you a PM

Thanks

Got it and your emails today. Will get back to you tonight, was away for the weekend. Thanks

Hi mate,

I have two IBM Bladecentre H Chassis 2880w

See here - https://bitcointalk.org/index.php?topic=1631365.new#new

I am looking to purchase two Breakout boards and 2 sets of PCI-e leads, wht is the process of ordering ?

Can pay via BTC and i am based in the UK...

Do you recommend running one or two s7/s9s of each PSU ?

Cheers

Have you tried contacting J4bberwock yet about UK sales? He is based in EU and would be way more affordable on shipping.  He has been difficult to get ahold of in the past though.

You can run 2x S7's or S9's of any batch on 1 IBM 2880W PSU.  It is literally a perfect plug & play solution for them, as long as you have 200+V AC input.

Finsky waiting on the pm. bump

Anyone know where to get the breakout boards for other (smaller) server PSUs?
Im thinking of the hp 1200w or 1500w

If you are looking for DPS1200FB-A and the 1500w variant using the "common slot" interface, I have boards for those too.

OP updated with option to upgrade to IBM 2980W Platinum PSU's.  For the first 10 PSU packages sold I will upgrade to 2980W PSU's for free!!!

Prices updated to reflect current PSU market pricing unfortunately :(.  If you have access to cheaper PSU's (which can be found in small quantities if you are resourceful), take advantage of this and save yourself some money!

This might be a stupid question. It how quiet are these? I'm looking for a cheaper alternative to atx psus for my home mine. Trouble is it's currently located under my desk.

Not a stupid question at all.  The answer:  Stupid loud  :-\

I do not suggest using this for an under-desk PSU.  It is on the edge of being unfeasible for use even in a basement/garage depending on your tolerance.  If you need that much power, you could go with the DPS-4K (another PSU board/packages I sell in my sig), it can be made as quiet as you like by choosing the 120mm fans for cooling. However if you are just replacing a ~1000W ATX PSU, you would be better suited with something like a DPS-1200 with breakout board.

Funnily enough I forgot I posted on this thread and ive posted on your other one asking something along the same lines as you've suggested  :D

Bump.  Stand-alone ATX-replacement GPU packages coming in short order! Stay tuned...

Bump for Bitmain's new T9.  I would recommend the Double A Package upgraded to the 2980W Platinum PSU.  Increased efficiency to help offset the efficiency on the T9, and 2980W to give a little bit of breathing room.

As before, I will offer free upgrades to IBM 2980W Platinum PSU's on the next 10 Double A packages purchased and will extend PSU warranty for 3 months, as I am confident they will power the T9's reliably. The 2980W Platinum PSU packages will be shipping from here in Canada.

Do you have any 110v options? I'm in Toronto myself, where exactly in Canada are you located?

Sorry, nothing in 110V.  Both the DPS-4K and IBM 2880W require 200+V, sorry!  I'm in Northern Ontario, about 4 hours north of Toronto.

OP updated to reflect lower PSU prices again!  :)

Away on Holidays from now until March 3rd! Trying to get everything shipped out before then. Will try to keep in touch, thank you for your patience.

Bump this up, packages shipping out daily. Still have a few platinum 2980W PSU's in stock!  Keep your eyes peeled for GPU-focused packages coming in the next 2 weeks.  2980W Platinum server PSU could power up to 3 full 6-GPU rigs without requiring ATX PSU's!

Hi Finsky,

i'm still waitung for your reply on my PM, thx

Do someone know if the 2880w PSU can really power 2x S9 on the long term ?
I made a test, and this is 3200w at the wall for two recent S9s.
The PSU seem able to handle it (Server PSUs are strong) but will it last long like that ???

Yes, they can really power 2x S9's long term.  3200W at the wall is exactly 2880W DC power consumption at 90% efficiency (since these would be considered max load).  I have hundreds of them powering S9's in Data centres for months now without problem at this level. My failure rate is ~1%, most of which is DOA's.

GPU Packages now live! See thread here: https://bitcointalk.org/index.php?topic=1864539.0

Bumping this up.  4K PSU's are not currently available until supply of DPS-2000BB PSU's are reliably available again.  Take advantage of the beast IBM 2880W-ers!  For GPU rigs, these can power up to 3x rigs with 6-GPU's per rig (or 2x rigs with up to 9x GPU's per rig).

How loud are these things?

Like having chalk tied to a fan spinning at 6000RPM against a chalk board. They are slightly louder than S7/S9's, but higher pitched.

I have one running in my garage. Helps me sleep at night. And no, I don't sleep in the garage ;)

Hello!

I just sent to you a PM related to a breakout board, please answer my friend!

Have a nice day.

PM sent on availability of breakoutboard and cables.

Sent you a msg looking to buy some hardware

Please note:  I had a very unfortunate incident today in which my commercial space was completely flooded due to the gross negligence of a tenant above me.  Losses are significant, I have spent all day moving my inventory off-site and salvaging what I could.  My time is going to be spent fulfilling existing orders as quickly as I can, but I will not be available to quote new orders (some of the PM's are a week old or more) until later this week when I get myself situated.  I apologize for the inconvenience, and for anyone with outstanding orders please know that I am doing everything in my power to get your orders re-packed from un-damaged stock and will be shipping it out as soon as I am able to.

No worries Fin, just get your stuff situated and get back to us when you can.  Sorry to hear of the situation.

Ive always wondered what makes these different than say the EVGA PSUs?

Appreciate the update.  You've got a PM from me in the huge pile of unanswered messages.   Take your time and let us know when you're back to 100%.  We appreciate you. :)

-cptgky

Any update on how things are going?

Has anyone heard anything?  Ive sent a few PMs but havent gotten any responses.

Anyone doing these in Europe atm?

Is it possible to get gerbers etc for these and I can have some made?

Apologies everyone, but for the time being I am not accepting any orders.  I am not able to provide an appropriate level of service at this time, and cannot commit to reasonable timeframes. I will update in a few weeks once I get caught up.

I am looking for these. Please let me know once your service resumes.

Thanks.

^^ Ditto.  I am using 2400w supplies on 14 GPU rigs and would like to try a couple 2880w psu's out.  It would make me feel better to have the extra headroom while dual mining :)

Finksy,

Are you back up and running yet?  Would like to get a couple IBM 2880W power supplies, cables, and picos from you.

The "Double A (Antminer/Avalon)" Package
how much is this package
can run 2 s9 aug batch 14th/s ?
thanks

+1.  Let us know how you're going Finksy.  I've got a few 2880W PSU's inbound presently and would love to get some adapters.  Otherwise I'm going to have to break out the soldering iron soon :)

Hope all is going well and you've caught up.. Let us know how you're going.

D

Waiting for your answer for oersonal msg

I might be looking for a psu to power 6 x 1080 Ti gpus. (complete kit with breakout board and cables)
Every card use 2 x 8pin power connectors.

TDP on one card is 250w.

How loud are the IBM psu:s ?
I am going to run this rig in my apartment.
If they are really loud i have to use regular psu:s.

Pricetag on this ?

I dont think Finsky tracks this thread anymore.

Does he have his own website now? Sent him a PM a week ago but if he has stopped need to look elsewhere? Do you know how to get in touch with the guy from france?

Hi Finsky,
I am interested in your 50A PDB.  I installed a 50A 240V welding plug in my garage years back and that would be perfect to power my rigs. Do you have any available?  If so, how do i order?
Phillip

Anyone know if Finksy is still operating? Would love to get hold of a couple of DPS-2980AB breakout boards.

He had some flooding and couldn't sell his stuff anymore.

He did not answer my request like a month or so.

So he doesn't do business anymore.

Could you pm me!

I am interested about the fans and psu!

hi

interested on this:

 - 1x Breakout board
 - 11x 24" PCIe cables
 - 11x 36" Deluxe PCIe cables
 - 1x C19 power cable of choice (see below for stock)

can i have final price?

I am sorry to hear this happened to him.

His last active post  was FEB 18 2018  so I guess he is out of the game for now.

Thats really sad to hear. I was either going to buy more, or I might sell all my gear off and close down.

If he really is out I might start selling off my kits. I've got a bunch of used full 2880 kits that Ive had in use for a while now. And quite a few spares.

I'll wait for our man to chime in first before I start selling over his head. Im curious how soon he's going to be before he starts selling again. Or is he gone for good? I hope he's working on a comeback. His 2880 kits saved me countless hours dollars and headache over using traditional PSU options for sure.  ;D

here my email timefordeals@gmail.com

i would like to order 

C19 to NEMA 6-20P (12awg, 1.6M) - $12 each

12  -36" Deluxe, high quality 16awg made in USA- $4.50 each


Board price - $65 each.

PSU (Refurbished)

The guy is out of business.

I'm in the market for a kit or two and/or breakout boards for these PSUs if anyone's liquidating. Thanks.
