soumalidon said:seriously i had such a bad exoerience with GPAL650AA, the reviews are good but i have my doubts on that PSU. It had problems powering my GTX260 and Q9550 all at stock, after struggling allot with it i jus replaced it with a TX750. But i did sell that PSU and the member who bought it had no problems powering his lower configured rig! Hmmm..
I that case why did you not opt for an RMA ? It could have been a manufacturing defect.
Because i have found various reviews where the psu comfortably powered crossfire setup like 4870+4850 & 8800 GTS SLI, i am yet to see any negative feedback on any forums regarding the PSU.
I just purchased one based one these positive reviews, Hope i do not face any such experience like you.
