The card will fit in the case. If you have that prebuilt, you might want to take a look at the PSU and ensure it is from a reliable company (Antec, XFX, Corsair, Seasonic) before you stick a $300-$400 GPU in it.
I have the Corsair Builder Series CX 600 Watt ATX/EPS 80 PLUS (CX600).
That will be fine for this card. its a good quality PSU.
