coil whine? Coil Whine because of PSU?

[LostAndDamned]

Specs:

CPU: i7 8700k: 4.7 Ghz 1.23v

RAM: Corsair Vengeance 3200MHZ 32GB

Mobo: Asus Maximus X Hero

GPU: EVGA 2080 FTW3: 2100 Core, 8000 Memory

PSU: Corsair RM750x

 

I was on a LAN a few days ago and my PC was connected to a Power Line that died out of nowhere.

I had a small noise problem before with my GPU but it wasnt this intense, only a slight noise that went away after I repositioned my PC. It could've been vibrations from my floor matt that is on a somewhat uneven wooden floor.

But now it is that way whenever my GPU is hit with a load (doesnt matter if stock speeds or OC). The moment I pause a game or close it, the noise is instantly gone.

I was wondering whether the Corsair RM750x might be at fault, cause there are many people that complained about general issues with that PSU on multiple sites and it might have taken a hit there.

I did read that sometimes a faulty PSU could be at fault if the power isn't clean or so on, but it wouldn't surprise me if it is the GPU after all.

 

General usage is not affected at all. There have been no difference so far from what I can tell, but the noise can really pierce through my open back headphones.

 

Any help is really appreciated!

Cheap fix is to buy a new psu and see what happens with the noise.

How did it go? I have a very similar setup and I'm suffering the exact same thing.

I have a 8700k (delid and OCed to 4,9 GHz. liquid metal), Maximus X Hero and 32GB of RAM. My power supply also is the RM650x...

I RMAed the mobo, and PSU. Still having the issue. It's save to say that it isn't the EVGA 1080ti FTW3, because i removed it and testet with intel graphics. 

I have no Idea left what to do. Maybe I'll pick another brand PSU. 

What worked for you?

I had found out that I got 2 noises, one was dependend on the placement of my case. I had it on some rubber mat and since I put my PC on the parquet, one of the sounds has never occurred again, which was a even weirder screeching noise, which I could remove for a while by moving my case a small bit. In my case it's the GPU. Removing it and using a old Geforce 9500GS or the Intel HD Graphics and it was gone. Sadly I just never have the time especially now to be without a GPU, as I need it for my studies. The PSU did nothing in my case, I tried the BeQuiet Straight Power Platinum 750w. Hope it helps, I was wondering whether vibrations might be a cause, but I'm not a expert.
