That also depends on other parts. But for typical systems, it should be good enough. Of course, any psu can be defective.

I have an Antec 500 watt psu and it works fine with my Visiontek 4870. I have had no trouble at all. See my specs below.

should be enough power maybe even a 2nd 4870 would work.

Should be just fine, running two 4870s here and load shows as 545 watts during Crysis and 378 at idle.

stoner133,
What is the best way to tell how much power your rig is using? What do you use?

Thanks!

Should be enough. Might even be enough for a second 4870 but that might be pushing it. The good thing is, it has overvolt protection, so if it activates then the system will switch itself off and you'll know you need a beefier power supply.
