Modular Power Supply
What Power Supply should I get for my GTX 275/285?
just curious. is the Cooler Master 700 Watt Modular Power Supply enough for those video cards? Not both of them in sli or anything just separately. i am going to upgrade to a gtx 285 but not for two more months.
According to nVidia, the GTX275 draws a maximum of 219 watts: http://www.nvidia.com/object/product_geforce_gtx_275_us.html (it's under the specifications tab). 219 watts is 18.25 Amps on the +12V rail.
The GTX285 draws a maximum of 204 watts: http://www.nvidia.com/object/product_geforce_gtx_285_us.html (also click on the specifications tab). 204 watts is 17 Amps on the +12V rail.
According to the specs page for the Coolermaster 700W modular PSU at Newegg, it has 50 Amps on its +12V rail. If you are going to run just one single GTX275/285, it's overkill. (the 275 would be 18.25 amps, and I doubt the rest of your system needs anywhere near 31 Amps.) You can run just one card on a Corsair 450W PSU with 33 Amps on its +12V.
If you want to run two of those cards in SLI, then that Coolermaster 700W would be a decent choice.
Hope this helps.
