My power supply is buzzing?

This is my PC build: https://pcpartpicker.com/b/hWtgXL  Just recently I have started hearing a buzzing noise from my computer, and I thought it was a fan motor at first but today I found out I may be wrong. When I unplug a fan or two from one of the motherboards headers, the frequency of the buzzing changes. I am pretty sure it's not a fan motor, as I have tested extensively. What are your thoughts on this? Should I replace my PSU?

Try fit in the power plugs more tightly. Just a bad connection between wires can cause buzzing when it conducts electricity.

Probably just coil whine, pretty normal so not much you can do (Harmless though).

I have coil whine on my video card, and the power supply doesn't sound similar to that. The sound is very deep and linear from the PSU.
