Alright TH community, so here is my conundrum. I recently built a new PC, and it's been running fantastically for the past week. There has been no glaring errors that I have had, and everything seems to be running at normal capacity. However I recently noticed a clicking noise accompanied by a strange humming sound emaciating from my tower. I opened up the case, thinking it to be the HDD. However I realized the noise was coming from my PSU/GPU area. I'm fairly certain the sound is coming from my PSU, however. My PSU is the Antec Trupower Classic Series 650w. My GPU is the Sapphire r9 280. I have tested a few issues. There is nothing blocking/obstructing the fan to my knowledge, and I turned off my case LEDs and room lights to check for arcing (I was unable to find any signs of it). I don't think it's a faulty fan bearing because the fan seems to be running just fine. I plugged my PSU into a wall outlet of mine on the off chance the sounds were caused by the power strip. The sounds still persisted. It could possibly be coil whine, but I doubt coil whine is to blame for clicking. I also turned on my second computer I have plugged in to the power strip (which is a archer s power strip), and the PSU from it was making a whining noise too. I'm pretty sure it is coil whine, and I just never noticed it before. I don't remember if my computer started making these noises off the bat and I just noticed them for some odd reason, or if my homes electrical grid is to blame somehow. I also wonder if the introduction of my new PC somehow caused the whine in my old one, if coil whine is not to blame. At any rate I would like some possible explanations for these issues, as I am drawing blanks across the board. Please do not suggest RMA'ing the PSU unless absolutely necessary (meaning you literally have no logical explanations as to what is happening). I only wish to do that as a complete last resort, as I will be extremely busy in the ensuing months.
Here are sound files of what the two PCs sound like.
