(1000w psu + GTX 280) or (800w + GTX 285)? Tags: Homebuilt Gtx Cooler Master Systems Last response: April 20, 2009 3:54 AM in Systems Share terminus April 19, 2009 7:05:59 AM There are both the same price. I was wondering though, should I get a (1000w PSU + GTX 280) or (800w PSU + GTX 285)? Here are the rest of my spces: -Sliverstone Raven RV01 -Asus P6t X58 MOBO -Intel Core i7 920 -Cooler Master V8 -6GB DDR3 1333MHz RAM -1.5TB 7200rpm 32mb cache More about : 1000w psu gtx 280 800w gtx 285 n3f0ur April 19, 2009 12:06:19 PM If you're sure you're not gonna SLI/crossfire, go with the GTX285. slizone recommends 1200w+ for GTX280 SLI, so the 1000w MAY not be enough. Helloworld_98 April 19, 2009 12:20:04 PM also the GTX 275 has pretty much the same specs as the 280 minus 128mb of VRAM and a few mhz on the memory clock. and if you have an i7 pc wouldn't it make more sense to get a 4890 and Overclock it?

The OP's rig with either of those gfx cards would be fine with a 650 watt psu . Total system usage maxxed out wont exceed 450 watts . ehanger April 19, 2009 9:29:39 PM LOL theres no way a computer with a single gtx 280 needs a 1kw PSU there are people who run GTX 295's on 650w rigs and do fine. irkjab April 19, 2009 10:04:13 PM So, in other words, both those PSUs are too much for the graphics cards. Where are you buying these from, and what do both those combos cost? I bet we can find you a better deal. geofelt a c 84 B Homebuilt system April 20, 2009 3:54:52 AM What brand of psu are you talking about? The GTX280 and GTX285 should have a 550watt psu with a total of 40amps on the +12v rails according to EVGA. The vga vendors tend to be overly conservative to account for poor quality psu's.
