Topic: IBM 2880W PSU/Breakout Boards - *NEW* Package deals for T9/S9 & A7 - page 16. (Read 40908 times)

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.

NICE

Is there anyone UK based doing this?

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.

I figured I was missing something. Thanks for clarifying

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:








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.

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:

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

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?

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

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.

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:

       

Feel free to contact the developer of these boards if you have any concerns, he will verify that I am authorized to sell these. https://bitcointalksearch.org/user/j4bberwock-206446

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.
