explain to me where you're getting the other 300W or so? last time I checked it's all but impossible to max out the memory chipset and CPU simiultaneously. I've seen a few reviews where a largely stock single CF system drew ~ 400W. If you're stock voltage OCing you probably won't have issues with a high quality 600W PSU(PCP&C tends to underrate their units for example). Not that I'd personally restrain myself with one, I'd just buy according to my needs.
