How do I run one of these bad boys in Canada with only 120 Volts?
I run mine off 120V, just use regular ATX PSUs that are single rail. However you do need a dedicated 20A circuit to be safe! I use a 1000W PSU (2 boards) + 650W PSU (1 board). Or get an EVGA 1600. I used a 1300W for a while but it was just too close to the margin for comfort IMNSHO!
The huge thing is not to mix PSU's on the same hashing board. So you need to power entire hashing board via 1 PSU. So it has been kinda common for 120 to use two. One that powers two boards, one does other and controller. It can work.
I like all in one but that is a lot harder to do in 120v area as evga 1600's are high priced. Compare to 220/240 server PSU's its a huge jump in price. But I still like one PSU for all if at all possible.
EVGA G2 1300W PSU............problem solved. Got 3 powering 3 S7 for the past 2 months, no issues. Just buy 2 extra dual PCI-E cables for $40 extra for OEM and cheaper for non OEM cables. I have an extra EVGA G2 1300W PSU at a good price if anyone needs 1. Will include the 2 extra PCI-E cables so you can have 10 connections to the S7 at no additional charge. Just PM me.
You can use the single OEM 6pin and buy good Y Splitter on the forum for 3.5$ per. Definitively works for S7's, but some S7 really cap out the PSU, so it might make some people nervous to see 1460W at the wall on their 1300W psu. No problem for the G2's anyways.
On a related note, anyone know where to get the short jumper cables for the EVGA 1300 G2? they are the female pins, unlike Corsair 750 that you can jump with a paperclip in the master cable.
Are you asking how to jump them? You jump them the same was as every other PSU, pin 4 with any ground. Tho all the EVGA's i've bought in a while comes with the neat adapter that jump 3 and 4.
I know how to jump it, but have to use the full 24 pin ATX cable and plug in the jumper module. I was looking at doing this without using the fat 24 pin cable and directly on the PSU. I have one setup like this, but need more of these little jumper cables. See picture.
Oh geez I'm not sure I would like those things. You get the wrong holes and it could be lights out for a very expensive PSU.
I did actually wonder though why EVGA didn't make a jumper thingy that plugged straight into the PSU like that instead of making one that required the cables to be plugged into the PSU only to have a cap put on the end of the cables to jumper it.
Well, its one time. Just count the holes and put your jumper in the same slots. Never have to mess with it again. I have actually then taped down the jumper cable to the PSU with electrical tape to keep it from coming out. These are great, I just can't find where to get them.
Think I found it, was looking for ATX stuff and these are just breadboard type standard jumpers mostly used for Arduino projects.
