FC3 won't boot on Gigabyte K8NS-Ultra-939

[Robert L Cochran]

You won't be able to use a cheap power supply with a 6800 card. And if 
the supply is really bad, it can damage your system components. You need 
at least a 430 watt power supply for that video card. Antec's top of the 
line supply recently got the best rating from Maximum PC magazine, which 
rated 7 different power supplies. You might want to read that. PC Power 
& Cooling's TurboCool came in second.
