Hello!



So I've got a coil whine which I've tracked to my PSU. The coil whine started when I got my . I've ran Heaven and CS:GO to see if the coil whine is tied to the fps but that doesn't seem to be the case. And unless my ears are lying to me I'm 99% sure it is the PSU. Only when I get close to 100% GPU usage AND around 35-40% CPU usage the coil whine starts (for example in the Call of Duty Black Ops Cold War menu).

The PSU is an EVGA Supernova G2 750w. I have tried another identical PSU and the same coilwhine occurs.



My question is, since my PSU is pretty old and the 3080 is known to pull a lot of wattage. Would upgrading the PSU to a PSU that wouldn't have to work as hard remove or decrease the the odds of having coil whine? I'm thinking a 850W.
