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

[Robert L Cochran <cochranb@xxxxxxxxxxxxx>]

Xconnect flunked the Maximum PC review. They did not reccomend it, 
citing stability problems and voltage levels on the 12v rail. I don't 
reccomend it either. You are better off with the Antec or PC Power & 
Cooling unit. I'll try to find the magazine issue to see if they rated 
the Uneeq.
