Is this PSU sound okay?

[Zem1akk]

Hi guys,

I have built my Pc about a year ago and for a past month my PSU is doing weird noises. This happens regardless od what I do (idle,game etc..) Of course its more noticable under a heavy load, but these recordings are while idling on desktop. (Basically I think the noise is related to the Power draw, sometimes at idle I am not even able to hear it but its vety rare)

I attached a vid Its like a electric buzzing sound. 

This is also VERY noticable when alttabing from games (GPU Powerdraw from 280W>80W), and no its not GPU Coil Whine, GPU Fans nor PSU Fan

 

Also I found a vid on YouTube if its hard to hear heres a link:

THIS IS NOT MY VID

 

Basically the Clip A and B are the same noise I have.

Oh and the PSU is a Corsair RM850 White(2021)

GPU: 7900 GRE

CPU: 7800x3d 

For anyone wondering

Yes, it is very hard to hear on top of the background noise.

Do you have a spare PSU you can use for testing ?

Its very difficult to hear what noise you are pointing out.

 

If its coilwhine then yes, this is normal on PSU's as well

Yeah I do but its pretty old and its like 350W or something like that. Should I unplug GPU before trying this one?

Sure!  All good

So, new PSU arrived. On the new PSU the buzzing/cracking electric sound is gone, but now the fan is too loud even on idle .

New PSU: Seasonic Core GX-850 ATX 3 (2024)

 

Sent back the first PSU to the retailer to get back money/new psu.

Also I had to attach a vid to the retailer so i uploaded it on yt: 

It was pretty hard to hear even for me(and I know what I was looking for in the vid) but from the Youtube one I think it's a lot more audible.
