More about will 630w juce
  1. AMD recommends at least a 500 watt unit. I personally would want at least a 650 Watt unit from a reliable brand, Corsair, Seasonic, Antec, PCP&C, XFX, or Enermax.

    You should be OK - in general these calculators build in a headroom safety factor.

    I'm not familiar with the fatality series. Google it and find reviews for it. If it delivers it's rated
    output and has sufficient amps on the +12v rail(s) you are OK.
    I wouldn't get a new PSU unless that one doesn't produce it's published specs.

    We don't get the BeQuiet models here in the states, but the reviews i've seen look good. :D
  5. Full system wattage with a 7970 is about 400w.

    I can't find a trustworthy review of the Fatal1ty 550w (a bad sign), however, I did find a trustworthy one for a Fatal1ty 1000w and it wasn't too bad.

    The one you have will probably handle it ok.

    BeQueit's newer models are well reviewed, but their older models were not.
    I suspect the one you are considering is an older model as the newer one
    is 650w not 630. Could make a bigg diff.
    You should dig a little deeper into the one you are considering.
