Server Power Supply Interface Board - for standalone miners and GPU rigs

[iGOSHi]

Do you have any extra PCI-E power cables for sale?

[sidehack]

Not really, at present. How many would you need? When sales open, boards and cables will be sold as separate units so you can buy one, the other, or both.

How do I go about ordering a few boards   I PM'ed sidehack,no response....yet......... 

Also what AWG is best for Antminers   


Thanks!!!!!!!!!

if using 3 wire pairs (3 12V, 3 GND) per blade, 16 or 18 AWG will work. be careful of 20AWG
if using 2 wire pairs (2 12V, 2 GND), 14 or 16 AWG - avoid 18AWG
if using 1 wire pair -> use 14AWG.  16AWG will get warm.

I've got an Ant running off three-wire 20AWG, 12" long. It's nonideal.

Thanks for the info  

I'll go with the thickest (14),just to be safe    I have a lot of PCIE 6pin males left over from a frozencpu purchase  

I made cables for 11 Klondikes & they worked great!!  

Double & triple ends:

Received mine today, they are top quality and to my great surprise there are spades on the end of the cables making my life very easy!

Top quality work!!

[sidehack]

Shouldn't be too surprising. Bare wire ends are for DIY, not retail!

In any case, glad they got there and everything's approved so far.

Well no insult intended. I am extremely happy with the product.

I now actually have more power supplies than I need!

[pmorici]

I'm going to close orders for now ... no further orders will be accepted until the current ones are filled and stock is built back up.

I just shipped the last boards we had ready to roll. We're gonna finish out the run before opening orders again. It'll be at least a week, maybe more.

Just saw these on eBay...

Looks like someone is reselling or selling a clone of BitHack's design for $80 or $125 for a full kit!

I'm betting that would be TracerX, who bought 10 boards and had them shipped to Oklahoma. Info matches up.

Dude, not cool. If I wanted them on eBay I'd be selling them on eBay, and my seller creds are better than yours. Also thanks a heck of a lot for crediting the actual designer, manufacturer and brand by putting your own name on it.

Guilty as charged!  I shot you a PM, as I'm not in the business of pissing off reasonable people.  We'll get it sorted.

At least the pictures show the pcie wires to be heavy gauge open loop U not - straight spade - that had me confused from a earlier discussion, the pictures help greatly.
SideHack you down with this ? cause it is the future. - till we run out of cheapo server supplies

[sidehack]

Eh, as long as credit goes where it's due. I and my guys have worked way too hard on this to let someone else rebrand it, but he's edited the listings.

I had planned on not opening general sales to the world until the next batch, keeping it to the forums until everything was pretty well ironed out and proven to be good. Not that I really had much doubt, but it is a bare PCB and there are a lot of idiots in the world.

I've got a noob question, what is the large capacitor for on the board?  Is that something specific to the Dell supplies I've been trying to jerry rig a few old supplies I have laying around of different brands just wondering if I'm doing something dangerous/wrong w/o knowing it?

[sidehack]

Yeah the way I figure, I've been losing around 13-14% to PayPal and eBay (refurb/resale online has been my full-time job for two years - ebay seller midwestrefurb - I estimate 14% on all bid transactions) so that would shave it down around $69. He paid $55.50 per set (board + 4 cables) when shipping is figured in, so that's a margin of around $14 per set at least for the basic set. I guarantee the supply and power cord didn't cost another $40 though, that full kit has a good margin to it. I wouldn't sell it that high, but then I also don't pay retail for the boards and cables. If you want them immediate though, he's the place to get 'em from I guess; it'll be another week and some before we sell again.


The large capacitor is there to assist the internal supply's caps in supplying burst current needs. Some miners pull a lot of current when they kick on, which can trip out a supply or bottom out the voltage briefly. It's not really an issue with these supplies, but a little help never hurts. The more stuff you have between the supply's output caps and the load, the harder it's going to be to push that burst current, so we put an extra cap right at the connector to help smooth things out.

Thanks for all the boards and cables.  When you have more ready I would like a few more.  Thought you guys would like this photo of a few power supplies too.
