CPU cooler- Corsair H100i
GPU- Sapphire r9 280x VAPOR-X
Ram- Kingston HyperX Blue 1600MHz
SSD- Kingston V300 120GB
HDD- Western Digital Caviar Black
Case- Cooler Master 690 II Advanced

If you plan on overclocking, at least a 650w. The power draw for that system is about 500w. If you are going to crossfire, check the prices on 750w - 850w and buy one from a good brand because it'll be cheaper to buy the Psu now, than replace the Psu down the road.

:edit: The Corsair CX series should only be used in budget builds. Any of their other lines are solid, but the CX(and GS actually) use cheaper quality components that aren't as reliable. Look for Seasonic, OCZ, XFX.

CPU- FX 8350(oc3d to 4.6 GHz) = 270 watt (read article here http://techreport.com/review/23750/amd-fx-8350-processo...)
CPU cooler- Corsair H100i = 20 watt
GPU- Sapphire r9 280x VAPOR-X = 374 watt max consumption (read arcticle here: http://www.techpowerup.com/reviews/Gigabyte/R9_280X_OC/...)
Ram- Kingston HyperX Blue 1600MHz = 10-20 watt
SSD- Kingston V300 120GB = 5 watt
HDD- Western Digital Caviar Black = 10 watt
Case- Cooler Master 690 II Advanced
fan optical drive etc etc = 30 watt.
well, that's all 729 watt..

so, at least you'll need 800 watt PSU to run your system..
