That is deinitely a possiblity as PSUs definitely degrade (sometimes output can drop 10% a year) How long have you had the True Power and has it had 24/7 use? If I remember correctly the 8800GTX needs 450W minimum and with an overclock plus overvoltage plus degrading PSU you could be well below 400W...Originally posted by: panoramarts
Maybe its a PSU issue. I am running Antec true Power 2.0. I dont have so much load on it. PSU never gave me problems on AMD and DFI.
OR its faulty board.
Maybe you could borrow a PSU off a friend to check it out.
Good thinking panoramarts
