Any concerns with 670's in SLI with a Seasonic X-660?

post #1 of 7
Thread Starter 
Debating picking up a pair of 670's for SLI. I currently have the Seasonic X-660W power supply. I believe this should be sufficient (moderate overclock on cpu, a few hard drives, fans, etc)

Any opinions?

Thanks

Yes its enough
Power draw from the wall would be somewhere around 550 watts give or take 25 either way

Definitely enough, even with heavy overclocks on the CPU and GPU's smile.gif

While waiting for a replacement PSU from Corsair, I put in the TX 650 V2 I had laying around and it has been fine for a week of gaming (e.g. Metro).

My system (stock):
3770K
Sabertooth Z77
670 FTW x 2
830 SSD x 2
MCP35X Pump
120mm Fan x 3
200mm Fan x 2
and one fan controller

Hope it helps. smile.gif

PS. I was using an AX 850 before it crapped out.

Yeah, that's fine...

pretty much the max I have seen (with max OC's) is roughly 700w from the wall.

Definitely enough, you can do dual 680's on such a PSU as well.

Thanks for the replies. I may just go with a single GTX780. It will be about $90 cheaper and I can then fit a discrete sound card on my MATX motherboard. I only plan to run a single 120hz monitor so it should be plenty.
