my PSU from PC is making high pitch noise while a move mouse. And another problem is what it make a buzzing sound after a turn computer off. And I think what fan is shaking with this buzz. Any one know anything about this?

Hi and welcome to the forums.

It would help us help you if you told us what psu you have. You say the fan is shaking? Have you had a look to see if one of the blades have broken off? As suggested above, it could well be coil whine.

Coil whine is very common with PSUs unless you go right to the top end.
