PSU weird sounds

[Ragebayne]

Hello I have a very weird issue with my psu it’s a decent tier one PSU but in one game it makes very strange noises that change pitch when I move around in game and it is only ONE game does not happen in stress tests or much better graphics games the game is car mechanic sim 2018 and I play much more graphically demanding games than this. I have put a sample of sound below I basically want to know 100percent if this is someth8ng to worry about or if I can damage my system this is a very very new build and cost me close to 2000 pounds I cannot afford to rebuild if this breaks things and it has me worried 

 

Maybe I can explain a bit more 

 

basically if I load game with no cars in shop it’s fine but minute I get a order and car spawns in garage and I look at cars the sound starts then the pitch of sound changes depending on where I’m looking on car 

 

also even more confusing is if I load car mechanic sim first thing in morning as soon as pC is booted I can play for hours with no sound from PSU however if I close game then play another game for a hour or so the re launch car mechanic sim I get sound when looking at the car I was working on with no issues for four hours 

 

thank you

In the recording it sounds like the fan blades are hitting something. Is your psu fan clear of debris?

lower pitched than coil whine so it sounds like a buzz. Probably the cables (espically the one that goes to the wall) isnt connected tight enough?

Fans don’t spin in this model at all until under extreme load

It connected properly to surge protector then wall socket could this be a issue? And would it really only show in one game

I’m 100 percent certain I took PSU out in long cables system was silent noise was from PSU in front of me but it’s one game that it happens only which is why I’m at a loss all other more demandin* games it’s silent even stress test it’s silent it’s just this one game

games draw more power, but not 750w, that PSU should not be making that sound at 50% load

I've got the exact same issue, thought it was some weird in-game noise coming from my speakers but it turns out it was from the PSU aswell

This issue isn't honestly bizarre and probably beyond any of our knowledge since it's so specific.

I would contact corsair support about this ASAP.
