Question Loud high pitch noise while gaming

[apie172]

In 2023, I did a new build (4090, 13900k, 1300W PSU, 64gb RAM) and it has been working great - playing any and all games at max graphics. Yesterday, a very loud high pitch noise starting coming from the PC when gaming. Initially, I thought it was GPU related and possibly coil whine - however, it is much higher pitched and louder than normal coil whine. I tried several different games, lowering graphics, lower frame rate, v-sync, etc - no luck. So I swapped out the 4090 for a 3080 (borrowed) and the same high pitch noise is coming from the PC.

I am not sure what else to do now. Would this indicate that there is a possible PSU issue?

Is the noise coming from the PSU?

Opening up the case and having the game running - while it is a bit difficult to tell where the noise is coming from - I think it might be the PSU.

What is this "1300 watt" PSU?

Press your finger directly onto the PSU. It will help you isolate the source.

Of course, stay away from any spinny things!

What is the exact make/model of your PSU?

EVGA Supernova 1300 P+ - actually checked the Amazon reviews and someone posted a video of the exact noise that mine is making.

It very well could be the PSU. One thing you can do is lower its load to confirm. Remove the GPU altogether and just use the iGPU (from the CPU). Does the behavior change at all?
