I was looking into building an athlon 64 shuttle, i would get the 250w ps but i was wondering if it would 1. be strong enough to power my 6800GT OC. and 2. would it run cool enough to remain on for days/weeks (sometimes) at a time. The 6800GT is overclocked to Ultra speeds. anyway i was just wondering if anyone has done this or knows enough about it to help me out.
