My Mac Pro PSU had been buzzing abnormally loudly for the past few days. Most commonly people are attributing these issues to Surge Protectors or a fault in the PSU.
Hoping it wasn't one of these, I did some testing, and discovered that it was caused by the Volex power cable my machine came with. Replacing it with another lead and swapping the fuse over solved the issue completely. Had no idea swapping the cable could be the solution to this kind of issue.
