PSU for 970 SLI watercooled build

post #1 of 4
Thread Starter 
Hello again guys.

I'm helping my brother-in-law(@cub3man) add a second GTX 970 to his water cooled build and am a little worried about his PSU being under powered. Right now he thinks he has a 600W PSU, but is going to double check and the make/model when he gets home from work this evening. As it stands PCPP is calculating 583W, not including the 18W DDC pump, for the build after the GPU upgrade. I think that's cutting it a little close but want to check with you fine fellows first. Thoughts?

Upgraded build:
AMD FX-4350(will likely upgrade to an 8350 in the future)
Asrock 970 Extreme4
Crucial Ballistix Sport 4x4GB DDR3-1600
2x Gigabyte GTX 970 WF3 SLI
Kingston V300 120GB
WD Blue 1TB
Seagate Barracuda 3TB
DVD-RW Drive
Asus PCE-N15 PCI-e WiFi Adapter
6x 120mm Case fans

EDIT: PSU is a rebranded OCZ ModXStream 600W to Kingwin ME-600. Having a quick look, it looks like there might only be connectors for one GPU, so we may need to get a replacement. Any suggestions?

second, for reference, my 970 with ridiculous overclocks and 6600K @ 1.488v load uses 315 watts from the wall. Water cooled. A nice quality 650 watt power supply will give him the head room (and connectors) he will need.

EVGA 650 G2 would be a good choice.

Yeah, that PSU was bought before we knew this build was going down this road. It was originally a budget build with a 750ti to be used for moderate gaming. I've used EVGA units in other builds without problems so was leaning toward that should he decide on a new unit. We'll have to see what kind of budget he has in mind for a replacement, but we'll definitely consider the G2.
