Depends on what ya got, your OS and connected items....I'd say nada on the 295....the others are cutting it close.
let this do the math for you....don't forget fans, USB (mouse, KB, etc), firewire, etc

295 = 194 watts
5970 = 168
285 = 140
5870 = 102
5850 = 85
Its ok, I already got the 5850 and on the box it says the minimum is a 500w 80plus which like you said is cutting it close but mine is a 550w and i only hace a gigabyte gpowerlite, ram cooler, and an extra HDD so the 50watts extra should cover that but exactly with a little allowance....... thanks anyway
