A dying power supply?...

I just noticed that when I turn of my computer, I hear this high pitch electrical sound coming from the power supply.
Does this mean that I'll have to replace it soon or is it nothing to worry about?

Btw, it's an Aopen 300W.
 
If it's a hiss or whine, it could be the mains filter caps.

If it's a slight buzz, it could be the main transformer.

Either way, that's a noise you shouldn't hear. Even a buzz coming from the transformer is something I only hear if the power supply is under heavy load... not in stand by.
