Question Weird noises from PSU

[MattCer]

Hi guys!
As I was rendering a video this morning, I noticed a weird buzzing noise coming from my relatively new PSU. After the rendering finished the noise was almost gone but I can still hear it when i get really close to the PSU.

Is it normal? Thank you!

Hi MattCer,

Does the PSU make a similar sound when the computer isn't doing any heavy work? I was going to suggest that it is coil whine which is very common in PC components, but this sounds different somehow!

Have you checked to see if any other components such as your graphics card are also making a similar sound?

Regards

Well I can hear it very slightly when my pc is not doing anything. When I am playing a game or something it is more noticeable. I think I can also hear it from the area of my GPU (
