Yes, I know. With a quad core, high end mb, 8gb ram, 2 dvd-rw, 3 7200 rpm hds and 2 4800 series cards, I get 689w.

I have Newegg.com - CORSAIR CMPSU-750TX 750W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Compatible with Core i7 Power Supply - Power Supplies and will get a highier one if needed.

Yes. Along with fans, etc... I think 750 should be enough. If not, can always get 850.

Kind of hard to select the wrong thing on the calculator. If you want a picture, say so. You can also show me how your getting your figures.
