Squeaky PSU Sound

[d0ks]

There's this ever so annoying squeaky sound coming from my PSU, not loud, but it's there.

The patient is a Corsair CX850M that's about 3 or 4 years old.

Dr. Google isn't very helpful when it comes to this kind of diagnostic.

HWMonitor goes like this. But i don't know how to read all these voltages, if it's in spec or not (aka does it need replacing or not).

 

Many thanks.

Damn.

 

Probably just some coil whine, nothing to worry about.

I think I know what you are talking about.  I had a Corsair AX1200i.  It had a squeaky sound under load.  Found out it was the cheap fan that they utilize in their PSU.  I have a silent build and I ended up replacing the power supply.

Sound is present regardless of load, be it full, moderate or idle :(
