Power supply buzzing sound

[Spbach]

It's a very slight noise, but when I put my head close to the back of my computer, there is a distinct buzzing. Does anyone know what could cause this? It is an HX 850, and it hasn't impacted performance or temperature at all.

Check for lose cables. That could also cause this

Joking! I will wait for a more specialized opinion, but I heard about capacitors that makes this sort of noise (that is kinda irritating) without any harm. But, I also heard that stuffed capacitors that are dying can make this sort of buzzing sound.

They shouldn't be dying, I just built this system 3 weeks ago

It also could be the coil because of load. If the sound is too annoying you can always replace it with manufacturers

I don't think it's because of load, I'm currently only using 500 watts

If you are in doubt with the sound then RMA the PSU. Under normal circumstances a good working PSU will operate soundless. So I think something is wrong and its hard to determine without physically seeing it that what causes the sound. Good luck.
