[TPU] EVGA SR-X Dual-Socket LGA 2011 Motherboard Teased Some More - Page 16

post #151 of 241
If you're planning on OCing both CPUs and all four GPUs heavily, I would consider more than one PSU. Also consider the power draw from the wall; you may need to run a dedicated circuit. Or two.

Noob alert again...it's possible to run multiple power supplies?!?!

Yes, though I've never looked into how it's done exactly. I know of quite a few people that use two PSUs for thier SR-2 setups. Usually one PSU drives the GPUs only and the other drives the rest of the system. This is actually a good idea even if you don't need all of the wattage but still want/need to fill all of the PCIe connectors on the board and GPUs. If you run quad 680s or 7970s and have the need to fill up all of the PCIe power connectors on the motherboard, you'll need 11 PCIe power cables (8 for the GPUs, three on the board.) No single power supply that I know of supplies this many. Maybe EVGA's 1500w unit will, but I doubt it.

I know you said you've never looked into it but do you think it would involve like wiring them together or just using the two separate PSUs.
post #156 of 241
Looks like I would just need one ofthese

They have to be connected together somehow because a PSU wont power on unless it gets the "go" signal from the motherboard when you push the power switch. If the second PSU is autonomous, it wont know to fire up when you push the button. I'd imagine there's some splitter thing that does nothing but jump start the second PSU when the first one is lit up.

Edit- Yeah, exactly.

So for the GPUs would my current 1200w cut it? and for the system would 850w work?

Scratch that...going to buy 2 new PSUs. Looking at Corsairs since they have sleeved cables now. Saves me work.

seems a little light on the VRM cooling, but i'm sure most users would LC anyways

As long as it doesn't catch fire like some lga 2011 boards....*looks at Gigabyte*
