I love my Antec True Power Trio 650, however its a suspect of possibly causing problems with my 8800GT. Aparently the 850w and 1000w quatro have been causing problems with some graphic cards like the 8800GTX and 8800GT.
Problem shows poor performance and low power warnings causing the cards to be under powered. Results show previous 8800GTS 320 scores of 10k 3d06 and with the 8800GT 1103 3d06 a drop of nearly 10k points.
