Asus MB M4A87TD AMD x6 1090T PSU Aspire Beast 650W
Have it stripped down to just CPU/Stock HSF built outside case.
Power on, fans spin for a second, then it shuts down. If i disconnect the CPU 12v, it doesn't shut down, the fans keep running, No beeps...
I don't have an alternate AM3 cpu for testing. New motherboard/CPU.

Do you have a different PSU to try or a PSU tester to check yours.
PSU was working fine in the system I am replacing/upgrading. It was an athlon 64 x2 5000 system with GF460 video. Old MB had an 8 pin cpu power connector, the new has 4 pin. 8 pin on PSU slit to two 4's.
reassembled the old system. PSU still working fine with that. I don't know if I should RMA the CPU or motherboard.
