When I unplug my PSU's cable and plug it again in the outlet, it starts making a high-pitched noise and starts trying to turn the PC parts on. The CPU cooler spins a bit, then shuts down again. The case LEDs are working.

To boot, I have to press the case button, then everything turns on fine. The PSU didn't do this before.

EDIT: Do I have to replace my PSU?

If it is still under warranty then send it in, and if not you could either fix it yourself if you have the knowledge and confidence or send it to a professional. If you don't want to do that then you could replace it. Also you could just live with the high pitch noise.

The high pitch noise could be coming from a capacitor or transformer but also could be that you are drawing too much current, or the outlet you are plugged into isn't providing enough amperage. You could do a simple test of trying on a different outlet and unplugging some components in your computer to see if that makes any difference. If it does not then like I said you could either fix it, live with it, or replace it.
