get atleast 450W, and make sure it has 350W+ on the 12V rail if your overclocking the cpu

i would think more than 450W i would look at getting about 500-600

after looking at the GeForce website it says that you need a minimum of 550W and if you are over clocking i would recommend about 650W just so you have some head room.

you don't post a budget. I would recommend a 500w-550w minimum PSU from a quality brand. some recommendations, you can research price and features based on what you like
seasonic 520w
antec neo eco / HCG 520w
xfx 550w
corsair TX 550M
OCZ ZT 550w
antec True Power New 550w

obviously the brands above offer more powerful PSU if you would like the spend the extra money.

I agree with the reccomendations you made, when wouldn't I ?
That review is from back when they were using Furmark, if they did it again using the "game-like application" they use now the result's would be just about the same as a GTX570

they did an 2-3x SLI test but also stated single card system figures in the 380-390w (as you stated, very close to a GTX 570 system)

System in IDLE = ~200 Watt
System with GPU in FULL Stress = 385 Watt

Graphics card IDLE WATT FULL WATT
GeForce GTX 285 194 381
GeForce GTX 285 POV EXO 194 389
GeForce GTX 285 eVGA 194 392
GeForce GTX 285 Inno3D 194 388
