IBM 2880W PSU/Breakout Boards - *NEW* Package deals for T9/S9 & A7

[cyptojoker69fl]

Any Royal With Cheese in stock?

[Finksy]

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.

[Finksy]

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!

[Finksy]

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!

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.

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

You managed to turn the fancoolers without break board?

I can indicate that I tap pin to light source 2880

[Finksy]

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.

Bump, packages shipping from stock. 

[dnyt]

PM Send, interested in 2 units.

[Finksy]

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?

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.

So I had to post up here and brag on Finksy.  Even after offering bounties (which I still have to pay and will) by FAR he was the most helpful in getting me up and running using just the server PSU's for GPU mining. 

They are loud but I have FAR less trouble out of them than consumer PSU's.  Also if you want to make them quieter it's pretty easy to build a box with mattress padding to cover the front (leaving the back open and not suffocating the fans). 

After making my own wiring harnesses it runs like a charm, they stay cool and the 12v wires are extremely substantial (I'm delivering 200w per wire and running 2400 to 2600w per PSU).

You won't regret dealing with this guy.

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

[rdnkjdi]

An autopart that Finsky recommended that can run a motherboard.

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

[Finksy]

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.
