IS Corsair CX 500 enough sufficient for GTX 560 1GB DDR5

I think I've done a blunder. I have recently purchased a CORSAIR CX 500 and now I'm planning to upgrade my GPU to GTX560.
Now the problem is, is it sufficient enough to drain the GTX 560.
I've a core2duo processor (E7500) and 2X2GB DDR2 RAM.
I recently added a CoolerMaster DI5-9HDSL-OL-GP CPU cooler (fan with heatsink) and 2 CoolerMaster 80mm exhaust cabinet fans...
Please suggest me, cz if its not sufficient then I will go for GTX 550Ti instead of GTX 560, cz no way I'll be able to change PSU again
And, please dont suggest me any ATI cards, please
Thank You

    You'll be OK with that Corsair CX500 PSU and a new GTX 560 or even GTX 560 ti graphics card.

  3. Thanks WR2,
    But will u kindly explain me the "efficiency of a PSU"....its 80% in case of CX500 and therefore I thought 80% of the rated output ie, (80*500/100) it like this??..
    Thank You
  4. 500W DC to your parts @ 80% efficiency means the PSU will pull 600W AC from the wall socket.
    PSUs are always rated on how much DC power they provide to the parts.
