Title: EVGA 1300 to Antminer S7 Post by: Jwells on September 11, 2017, 11:28:15 PM Can anyone please tell me exactly how to hook up the EVGA 1300 to the Antminer S7? Can it be done with only the cables that come with the EVGA 1300 or do I need to purchase splitters? Only 6 VGA's on the EVGA 1300. Thanks in advance. This is my first set-up.

I don't remember offhand if the S7 needed 7 or needed 10 though. Worst case, talk to EVGA about getting a couple extra of the "2 connectors on one cable" cables.

S7 needs 10. When I order more "duals" how do I arrange them? The EVGA 1300 G2 only has 6 VGA's.

Also, there are very few PC power supplies that come with even close to enough PCIe plugs as the S7 needs 10. They were never made to be ran with PC power supplies. Title: Re: EVGA 1300 to Antminer S7 Post by: QuintLeo on September 12, 2017, 07:15:37 PM S7 stock is rated for a hair under 1300 watts - but I agree that running one on a 1300 watt supply if you don't DOWNclock it quite a bit is a bad idea.
I suspect most of them on EVGA supplies were running the 1600 G2 or 1600 P2, or were the S7-LN model that only used around 700-800 range. Title: Re: EVGA 1300 to Antminer S7 Post by: HagssFIN on September 12, 2017, 07:19:01 PM ATX power supplies are not designed to handle 100% load all the time.
Server power supplies in the other hand are.

The first 2 batches of 54 chip S7s maybe. The 45 chip batches were much less efficient and every one i have tested at full speed pulls more than that.

They were never made to be ran with PC power supplies. the evga 1300 g2 can't really run an s-7 at full speed. if the op has the ability to lower the speed on his s-7 to about 4000 hash rate he could do 2 cables per board this setup would pull 4000 x .26 = 1040 watts 1040/6 = 173 watts a cable @ op the advice above is pretty much how to run your s-7 on a 1300 evga you would have a quieter machine if you do it. and it would hash at 4000 vs 4800 |
