very interested in the 2880 and the break out boards.

When will you have these? I'd like 5 in Canada

Hi everyone,

I am the official North American distributor of Break-out boards for the IBM 2880W PSU's, which are 80+ platinum rated (94%+ efficient) and have provision for 22x PCI-E cables.  Unlike other server boards, these don't rely on screw-down terminals 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 2880W PSU's are also more efficient than the DPS-2000BB's @ 94% efficiency.

The PSU's themselves are available on e-bay and elsewhere (I sell them for $60 each), and the boards will be priced at US $70 each for 25 or less (better pricing for bulk purchase, volume structure will be the same as J4bberwock's). Each PSU can handle 3x SP20's, 5.5 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). 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.

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).

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://bitcointalk.org/index.php?action=profile;u=206446

Board price - $70 each.  Orders over 20 will follow J4bberwock's future pricing structure

PSU (Tested used) - $60 each

I can supply PCI cables in two different configurations:

-36" copper-wired, high quality 16 AWG cables (J4bberwock's design) - $3.50 each (Waiting on shipment)

-24" standard 16 AWG cables - $2.50 each (In stock)

-C19 to C20 cables - $12 each

Shipping prices will be as follows:

CANADA
1-10 boards -$10
11-20 boards  -$15

USA
Shipping with tracking (from Canada)

1-3 boards     -$15
4-7 boards     -$20  
8-20 boards   -$25  
-If you don't need tracking and would prefer just proof of shipment, $5 can be knocked off each price point-

Shipping for orders with Cables or PSU's 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.

Thank you for your time,
