Question

Answer 1

You need to consider more than just the power supply and video cards.  You also have to factor in the number of hard drives, cd/dvd roms, mobo, case and processor fans, sound card and what kind of devices you will be connecting to the usb ports.  Essentially you need to total everything up that uses power.  Also factor in an additional 10%-25% for future upgrades.  Here is a site that offers a free PSU calculator if you don't want to total everything yourself.  Good luck and happy building!
