So I have been using Corsair TX 850M PSU(2013) for 7 years now, and it has held up quite well to this day. Back in 2014, there was a coil whine issue when fan the PSU fan was idle, but instead of RMA ing it(stupid idea), I replaced the fan and it fixed the problem for good. I have built 3 different systems with this PSU and now I am using it with Ryzen 5 3600 & GTX 1080Ti OC. Anyways, when the system is under load, there is a loud coil whine coming from the PSU and GPU, BOTH! At first I tought it was only my GPU but when I put my head at the back of the PSU, it was there too, with the same high pitched frequency as GPU. In my previous system build with this PSU, my 5700XT had coil whine too. If I change my PSU will coil whine go away? I ditched my 5700XT for many reasons but coil whine was the nr.1 issue. Thanks for the help!

Then it wasn't actually coil whine, was it?

No guarantees.  But it's an old PSU. Might as well replace it.

I think some component in the PSU was resonating with the coil in the PSU Fan. Or vice versa. I slapped a Noctua NF-P14 on it and it is doing good, never heating up. If I save up some money the first thing that I would do is replace my PSU...

No.  The fan motor itself was going bad. 

 

At any rate.. Replace the PSU.  They're not supposed to be used that long.
