Buzzing Noise Help Needed

[Evocashious]

A while back I started getting new upgrades for my PC. My PSU died so I figured while I was at it I'd get a 1080 Ti since they dropped from $1,200 to $550. But I've been getting a constant buzzing as long as any game is open. Browsing the internet nothing happens though. So while I'm not advanced at tech I tried some basic stuff. Nothing works. So here is a list of what I've noticed and tried. Maybe someone can figure it out.

 

 

-As soon as I boot up a game the GPU starts buzzing and you can hear it through headphones attached to the computer.

-The buzz goes up and down with FPS.

-Looking around I saw a sound card might help. It didn't.

-Buzz gets louder when you go into sounds and listen to the mic.

-Changing mic/headphones bit rate changed the sound of the buzz slightly on a few options but never went away.

-Disabling other devices

-Tried unplugging front panel audio.

-Unplugged mic and it's phantom power supply.

-Plugged PC directly into wall instead of 6 way.

-V Sync does nothing.

-Put my old 780 Ti in and it buzzed too.

-Others in discord can hear it through my mic.

-Using wireless headphones I don't hear the buzz unless I listen to mic.

 

 

I think I've done more but listing it all out I'm having a hard to remembering. Any and all suggestions appreciated.

 

Link to short 18 second video of the buzz and me trying to show the black chips on the back I think are the source of the buzz.

Sorry for the poor video quality by the way. Just trying to use my phone. It's the line of black chips towards the last couple seconds.

Its called "Coil whine", very common thing among GPUs. Its not dangerous in any way, just annoying if you hate high pitched noises.

That's probably coil whine from the VRMs.

This would make sense because as the game fps increases, the amount of power the GPU needs increases as well, so the VRMs are working harder. Its not harmful or dangerous to you or the GPU; its just a thing that happens with a lot of cards. Depending on the card, coil whine can be a lot quieter or be drowned out by fans; its all dependent on what VRMs are used and the rest of the PC's acoustic profile.

 

No idea what the mic issue would be, other than your mic being too sensitive and picking up the sound. You could try lowering mic sensitivity and/or volume to mitigate or fix this, if you can't fix it this way you may just have to use push to talk. What kind of mic do you have? USB or 3.5mm?

It's a 3.5 however it's still there even when Unplugged. Read it might be my mobo sending it through audio. But it wasn't there before my PSU died on the 780 Ti. Could be the PSU some say. But my other PSU died so I can't test it. Some said it could be a grounding loop. Might try to get something to take that out of the equation.

Would a half-decent DAC be able to remove the coil wine? I have read some people can get rid of it with those. Although honestly I have no experience with that kind of stuff. I'm more of a casual tech fan. 

I saw this on Amazon. Not sure if it's any good. Suggestions?
