(1000w psu + GTX 280) or (800w + GTX 285)?

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

  1. 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.
  2. 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 .
  4. 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.
  5. 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.
  6. 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.
