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.

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

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.



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

Too bad these are 220W.  Cry

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.

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.

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.  

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.

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.

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

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.

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?

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