The Fermi Thread - Part 3

[GoldenTiger]

It would probably work in general but would be pushing the power supply to its max depending on how much cpu and gpu load is applied at any one time, running prime and say fur at the same time might kick the ocp.

A system with my specs in a firingsquad review pulled around 410w from the wall:

i7 920 overclocked
6gb ddr3
radeon 5870 stock
2 hard drives
1 ssd (in mine, at least =p)
several case fans

So, a GTX 480 with a 250w TDP, and let's say 240w real-world draw... compared to the 5870 with a 170-180w draw if I recall correctly, would make you hit around 470w... so as was said above, with an Earthwatts 500w you're going to be pushing it: it will run but it will definitely be hitting the PSU hard, I wouldn't count on overclocking the vidcard at all. I think the quad you have is a little lighter on power draw, but same difference for the most part.
