PC Desktop power supply ticks

I have a desktop pc that does not power up. Power cable is fine (checked). The power switch on the front of the pc does nothing. The power supply unit does not smell as if burnt out. But when the power cable in the power supply unit a faint ticking can be heard like an old wrist watch. Is this the time to replace the power supply unit or is it more serious. Thanks in advance

When things tick, it can be an hard-drive, fan or perhaps psu.

Depending on the age, wattage and usage of the existing unit, then a new psu might be the answer. Have a look on eBay for a replacement. I buy my 350w/500w psu's from there for £10/£14 delivered.

Easy to check using the paper clip test. It's a simple means to bypass the switch on the front of the PC. The video is quite long for a simple job, but is useful if you're not used to working inside the box. The voltages involved are low, so no need to worry.

I didn't say the voltages withing the PSU were low - the voltages on the mobo plug, which is the one involved in this, are. I agree you should never open a PSU as they are not repairable.
