Nvidia lowered the power requirements for this series. Anyone try using a 350W PSU with a Pentium D and one 6800 Xtreme? I know it will be close, but only one HD & one DVD drive, no PCI's, & external powered USB hub using with an Asus P5ND2-SLI MB with (4) matching OCZ 512kb dimms. Asus's minimum per docs is 350W using two PCI express graphics cards. I searched for the power requirements for the XFX 6800XT, but only found guidlines stating a 450W minimum PSU.
