You would not be able to run if your PSU were producing those voltages.
Check what your BIOS says about the voltages.
And you can verify the main operating voltages with a multimeter. Yellow wires should read 12 volts, red 5 volts, and orange 3.3 volts. All readings should be +/- 5%.
Ok thanks, u put my mind at ease. All of the bios readings are pretty close to where they should be, the 1 exception being the 12v rail which goes from 12 up to 12.2 volts max, is 12.2 too high? I know u said +/- 5% but i tend to worry about every little thing
