PSU Coil Whine - Diagnosis & Solutions

So I currently have this very strange staccato whistling noise coming from my system:

I'm having a hard time telling if this is related to my PSU or GPU. I currently have my GPU pulled from my system and am running on integrated graphics, but are there any tests I can run to tax the PSU and check to see if it's making this noise?

Furmark will tax the gpu, which should pull more watts than the rest of the system.
