This only recently started, I've had problems with coil whine before I switched from some cheap PSU to this current PSU but now its back.
Initially the buzzing noise was only from the GPU, which upon researching should just be coil whine from my GPU. But recently my headphones plugged into the motherboard's integrated audio started buzzing in unison with the GPU buzz. The buzzing on both the GPU and Headphones both only occur when the GPU is under load.
I understand that a PSU swap might fix this but I've already forked out quite abit of money for the current one and I'm afraid if I go all out for like a, seasonic prime ultra platinum the problem will still persist. I have a spare RX 470 that I've lended a friend and might try swapping that in to see if the buzzing noise on my headphones will still stay.
Below are my specs for your reference:
Intel i5-9400F
B360M Aorus Gaming 3 Motherboard
16GB DDR4 2133Mhz RAM
EVGA GTX970 Hybrid Gaming GPU
SilverStone Strider Gold S Series ST75F-GS 750W PSU
[Storage is Irrelevant I believe]
Just looking for a potential fix or what might be the cause of the problem, any help is appreciated thanks in advance!
