Question PSU buzzing

A buzz from a PSU can be caused by lots of things.
It might be electrical.....like a coil whine scenario.....or it might be mechanical....like a bad bearing or fan blade interference.

I would try and find out which.

Sometimes you can just stop the fan....and if the noise goes away you know it's the fan.

If you can't figure it out and it's driving you nuts.....I would just get another PSU.
