so 800 watts from the psu while running linx and furmark? do you run them 24/7 or do you use you pc for normal things like gaming or such?

Recommended PSU from ATI was 650W at 70% efficiency.
and the 1000w is also 70% efficiency, AMD/Nvidia always idiot-proof those requirements so that practically any PSU at that rated wattage will run it ok.
it takes no genious to figure out 70% of 1000w = 700w. So I would reccomend a good quality 850w such as the Corsair AX850, XFX 850w or the Seasonic X850. All of these units are very high quality and made by Seasonic, so each will pull up and beyond 850w with gold/silver (87-89%) rated efficiency. They also can pull up to 840w on the 12v IIRC
you got efficiency backwards a good psu will do its rated power, efficiency is to do with the conversion of power and the loss during conversionEdited by obsidian86 - 4/18/11 at 10:00am
