650w should be perfect with headroom.

650w should be perfect with headroom.

650w is overkill for a single gpu and doesn't give much headroom for another gpu. 

A decent 550w is already more than enough.

A decent 550w should be fine for single GPU, you might want 750w if you're going SLI in the future though.

 

BTW your case choice is great, but the new phantom 240 is epic for its price! I built in one yesterday and it's fantastic! Just thought I'd point that out so you could check it out - worth a look

550 wats like W_M said, but trust me even a 450 watts will work , the power sdraw is evened out on 450 watt range & buying a more Power draw PSU isn't going to be of any advantage unless you have a ton of other expansions going on in ther, OC3D did a test on this , pretty much 450W can do most of the stuff on mid-somewhat high tier GPU.

Calculators are notorious for giving wildly different estimates. That one isn't very good as calculators go, as it doesn't give an actual Wattage but rather tells you which of their own power supplies to buy, hinting that you should get the more expensive ones.

 

500-550W is fine.
