Need help determining if my PSU is good enough.

Hey guys, so at first I was going to get an EVGA GTX 760 but then saw that the SAPPHIRE R9 280x DUAL X was better for a similar price. I looked up the card on Sapphire's website and it said that a 750w PSU was needed. I was wondering if the PSU I already have would do fine or if I would need to change it in order for it to run.

PC Build:

Current PSU:
XFX 550W 80+ Bronze Certified ATX Power Supply

  1. Yes you should be good to go. If you plan to do overclocking on your CPU and GPU you may need a bigger unit.
  2. If I did want to OC would I need to buy the 750w PSU?
  3. Best answer
    As long as your on a single card, I can't see you needing any more than a high quality 650w honestly. Such as the 650w version of what you currently have. If you had an Intel build you could get away with the 550w unit. The FX chips are know for eating up signifigantly more power while overclocked.
  4. Ok. I don't think I'll be overclocking much, just wanted to know in case I ever want to. Thanks for the help.
