the Antec True Power PSUs tend to have droopy rails. the voltages they output is VERY stable but a little on the low side. for example, the 550w True Control i tested had 3.2/4.7/11.4v on the respective rails. they're good PSUs, but when under a lot of stress, the rails just can't keep up.
my BFG 6800GT OC is at 430/1150 right now. i'm using a PCP&C Turbo-Cool 510 Deluxe. i'm gonna let it burn in overnight and then see if it'll do 440/1200.
