PSU for Xfire 4870x2? Tags: Graphics Cards DVD Drives Graphics Last response: July 16, 2008 11:19 PM in Graphics & Displays Share Kaldor July 16, 2008 3:24:54 PM Any ideas on a PSU for running Xfired 4870x2's? I am uncertain if a PCP&C 750 will be enough to run both of these cards, along with 2-3 HDs, 2 DVD drives, and an OCed E8400 @4 ghz. Do I need to start thinking about 850 watts or more?

Brands doesn't matter at this point, it falls far too short. 850w likely won't either. It'll probably be in the 1000w range. Can't find your answer ? Ask !
