Overclockers Club is holding an XFX sponsored contest to give away two power supplies; a 750W and 850W. To enter just click the link to the XFX Contest forum thread, and post what system you would put the PSU in, if you won. There is only one entry per person and is only open to residents of North America (sorry to our international friends). The contest has already started and will end next Friday, October 21 at roughly 6PM pacific time.
Good luck everyone.
