Sounds like the PSU might be faulty. How old is it? Have you experienced any other problems, eg random shutdowns etc?

It's possible one of the caps is failing/has failed (not much experience with PSUs unfortunately; usually just use 'em til they go up in smoke biggrin.gif), if you have a spare PSU/spare PC try swapping around to see if the problem is replicated.

Could just be coil whine on one of the transformers.

It's coil whine from one of the inductors. Nothing to worry about.

Can be solved by slapping glue on it using a gluegun (or just turning it off).

Read link in sig for more information.

As long as it continues to work fine you've got nothing to worry about.
