High pitched sound at seemingly random times Options

[Hintswen]

My computer has been making a high pitched sound at what seems to be random times. It's a long sound and can sometimes last for hours. It hasn't happened any time I have been in a position to take off the side of my care and try and hear what it is coming from though.

It would most likely be the power supply right?

I previously had an antec neo (still got it just not used, at work on my desk)

2nd antec one i've had in 7 years, never had an issue with either of them

think i've currently got a corsair if I remember correctly

cheap PSU usually ends up causing lots of stability issues

In the end like all electronics they're probably made in the same factory and rebranded, then it's just a choice of modular or not and how many electricity's you want
