I have 2 questions right... 1. What do you think a core i7 cpu and a ASUS P6T with 3gb three way ddr3 will need in watts? Including something like a 200 series gfx card and 2x 300gb HDDs. I would of thought around 850w but im starting to think whether that's actually needed. maybe a 750w or lower? 2. After that, say this build came to be... what one would you pick? I originally thought the zalman 850hp (because its quiet and modular) but the HX1000w sounds dam good. A power supply that is modular im talking about here.
