    Neah, even a 650W power supply would do the trick, but on the long run it's better to have more headroom.
    Anyway, the Antec is $109.95 at Newegg with a $20 mail-in-rebate and free shipping. Can't beat that.

    According to this chart 5870 in CF pulls 400W max and typical 300W
    http://forums.atomicmpc.com.au/index.php?showtopic=264

    I don't disagree with you at all Lemmy, but personally I would put a 70A PSU in an all new rig that size.

    Wouldn't the typical load while gaming (presuming the game worked the cards of course) be around 500W? What do we consider ideal? 60-70% or 50-60% work load? Maybe it's just my uncertainty on that point that makes me want a bit more.
    i7-2600K W/Apogee XT block, ASRock Z77 Extreme 4, G.Skill 2x4GB 1600, Powercolor 5870 W/EK full block, Seasonic X650, Intel 320 160GB, Caselabs M8

    i7 @4.1GHz, Crossfire HD5870 = 690W AC in Furmark + Linpack.
    In games should be waaay lower so I'd say that a good 750W PSU is sweet spot for this config.

    For some reason, the statement "good sturdy PSU" got a chuckle out of me. Like we're looking for a PSU that can haul a sack of grain on it's head and has good birthin' hips.
