Can I power two r7 370's with this psu? The rest of my system specs are also listed.
that is a terrible setup, don't buy two of those gpus if you already haven't. the R7 370 is an overpriced, twice rebadged HD7850 anyway. for the $300 two of them costs you can get much better performance from a single GTX970 or R9 390, not tom mention 2x-4x the vram and no microstutter or any other problems that come along with crossfire.
Yes, yes you can.
