  1. Best answer
    I would think 650W is enough. If you really WANTED to upgrade the PSU, I'd go with the Corsair CX750M of those options, given your limited budget.
  2. Your current psu will be more than enough. Game on!
  3. Your current , PSU is a good one made by the best in the business (Seasonic)and will more than power your system.
  4. XFX ProSeries XXX Edition 650W is perfectly sufficient for that spec. Better don't waste $$ :no:
  5. Sorry guys i was wrong

    My current PSU: XFX Core Edition PRO550W :??:
