C1 errors, hmm. That's what my defect not jet rmaed 9500 also does.
Have you moved the setup (cpu+hd) from 790FX to 770 chipset without windows reinstall? If so have you had issues with monitoring apps?

Beside it's bad that the psu is defect the software seems to be usefull.

My power consumption examples where all measured with the power meter, the psu did not arrive yesterday.
