Is a Coolmaster Realpower SLI 550w 80 PLUS PSU usable for a 5870, 5850 or a gtx 285? I have a basic dg35intel mb with 2 hdds, a dvd burner, gigabyte cpu cooler, led, and 4gigs of RAM, I guess these dont use many watts, but with all of this would a 5870 or any of the other cards mentioned above at full load work with my current PSU. ITs 80plus but since it is already 2 years old it might be a bronze standard by now... I also doubt that the gtx295 would work but if so would it too?

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
