My PSU (Rosewill Capstone 750 Gaming, 80+ Gold, 750W, Semi-modular) recently started making an electrical sounding buzzing noise that seems to come from the place where one plugs in the cable. It only started doing it around a month ago, though it tended to go away after I had my PC off for a few hours. I thought it was a one-off problem, but then it started becoming more common.
It can get quite annoying when not using headphones as it is at a different pitch to my fans.
The noise definitely sounds electrical. The sound is affected by wiggling the power cable, and is audible when the system itself is switched off, even with the PSU switched off. It simply needs to be plugged in. I bought the PSU new in May. The volume of the noise tends to vary, sometimes getting louder the longer the PC has been switched on.
My specs:
Ryzen 5 1600 (stock cooler) @3.5GHz
GTX 980 Ti Asus STRIX
16GB Corsair Vengeance 3000MHz, running at 2666MHz
Asus PRIME B350M-A
NZXT S340
What can I do to get rid of the noise permanently? Will it be a risk to machine? Should I RMA it?
