Testing HX850W


Recommended Posts

I am in the midst of building a new PC. I added all the bits I had but the PC failed to boot - no beeps but fans, MB lights, DVD and HD drive all show activity. So I am in the process of trying to identify the problem.

I wanted to make sure the PSU was working so I bought a psu tester - have to admit as I was to chicken to try the paper clip test. Anyways the fan works and all if the LEDS in the tester light up bar the -5V one.

+3.3V, -12V, PG,+5VSB, +12V and +5V all light up

-5V no light

Is this normal?

I now have to test my RAM, CPU and MB:(:
