a good power supply is cheap insurance, there's absolutely no excuse to not buy the best psu you can find. otherwise, you will likely end up buying another power supply AND motherboard.
personal favs: LEPA P1375-MA Enermax EPM1350EWT Thermaltake TPX-1475M Enermax EMR1500EWT Lepa G1600-MA

I am just going to be powering the GPUS so a 1000w will do huh?

no reason to get such as small psu. even with 130W headroom that's still running at 87% load. no reason to buy a slightly cheaper psu and put that much load on it. just spend a little bit more and get the biggest & best psu you can find. again, cheap insurance.

I agree with you epixoip but a 1000w would work ok, no? Pyrex, techPowerUp has a good list of PSU reviews which may help you pick one. . |
