Possible PSU failure? Symptoms...

Mythixus · March 14th, 2007

Aside from the few temperature issues I've been noticing with my system, I have also recently had some issues regarding power.

On a cold boot up of a computer (when pushing the power button on the front panel), it takes usually 15-25 seconds before the computer actually powers on and starts POST, etc.

Recently, however, I actually have to flip the switch on the PSU to off, unplug the cord, reflip the switch to on, THEN plug in the cord with that power on (which probably isn't the best idea), then I can start it as normal by waiting those 15-25 seconds... otherwise it won't start period.

I would test the voltage rails but I do not have a multimeter, and I'm still not sure the PSU is the issue.

My PSU is a modular Antec 480w, I believe, and I haven't always had this issue. For some reason though I had a similar issue with my older system that has a completely different mobo, PSU, and other parts. So I'm stuck.

Can anyone else relate to this?

pull the side panel off your system and try booting it using the onboard power switches.....if you see the same problem with using the built in switches, I'd uspect your PSU is going out

Oh yes I also did try those switches but it has the same issue.

Thanks for the quick reply :)
