More about which size powersupply need
  1. Yes. 500w from a good name PSU will be more than enough.

    Hi - Yes 500-550w(quality brand) is fine, in fact realdardtech suggests
    you only need 430w for a sys with a 5770.

    Personally, I'd get the 550w if it was within my budget as you
    would most of the time be in the "sweet spot" of the PSU's
    efficiency range (40-60% of max output)
