  1. Hello All,

    I have a very good Antec TruePower v2 480W psu (decent +12, 36A), and I was wondering could it power my new rig?


    Energy Efficiant Q6600 Intel Quad @ 2.40
    4 x 1 GB OCZ Platinum
    1 x 8800 Ultra
    1 x X-Fi XtremeMusic

    and a couple of 120mm fans...

    According to power calcs WITH %20 capacitor aging, the power demand should be around 478W...

    hey hey.... Personally i think you're gonna come up short on power... i say this because NVidia recommends atleast a 450 W power supply on the 8800's. Add the quad and the the other accessories and i don't think your power supply will last too long.

    Ya that will work for a while but it will bring you to a world of pain shortly after.
    If you dont have alot of moeny try for a thermaltake thoughpower 650 watt or something like that

    What power calcs?

    TechReport's review of 8800 Ultra with Core 2 Extreme X6800 used 315W on full load. I find it hard to believe that your setup would require that much more.

    You have 33amps, not 36:

    See if this would do for you:
    The 450w version has 33amps if that gives you an idea

    It will work.

    I too think power calculators are a joke. I have a Kill-a-Watt meter and ran my C2D with an 8800GTS, 2 hds, 2 burners, under full load and used 248W max. Power calcs did say it woudln't use much, but they were still up in the mid 300s.

    So you used a calc, and gave yourself 20% headroom and STILL came up below your PSU's output.
