does the XFX R9 280 really need 750w PSU?

will a XFX R9 280 work well with my EVGA 600B PSU, and if not can anyone suggest a good PSU that will?
also here is its spec sheet for 80+ verification if that helps http://www.plugloadsolutions.com/psu_reports/EVGA_600B_600W_ECOS%203706_Report.pdf

  1. No it doesn't. It'll probably pull 250-300w power on its own. You should be fine with the evga 600w.
  2. Best answer
    The EVGA 600B has 49 amps on the 12v rail and is sufficient to run the R9 280.
  3. well if you have fx-8xxx i would buy 750W PSU, otherwise i don't think you need that much
  4. thanks for the response guys
