CPU POST test fails w/ my 520 and 420 PSU but not with my 300. After switching on and off about 3 times it works with my 420 and 520 until I turn it off for a little while.
My computer fails the CPU POST test with my 520 and 420 watt Power Supply's, but if I switch the power on and off it will work until next time. It always works with my 300 watt PSU.
