High pitched noise from the PSU when the PC is off

[_xyz]

when the pc is off (but conneted to AC power), the PSU (new CoolerMaster elite 460) produces low level high pitched noise.
is it a real problem or should i ignore it?

I fully realize he is not stressing the PSU. At Idle he is probably around 100 watts, and I dought that he goes above 250 W max. This PSU, regardless of who made it, is very close to being “crappy” as you put it.Bear in Mind, “low end” PSUs do not need to be stressed to fail – when stressed they almost always fail, the only question is how long will it last and will it have a greater pensivety to take out other components.

The review you linked to was very polite in their conclusion. It is just a 400 watt PSU relabeled as 460 Watts (Shame on FSP). No OCP or OVP on the outputs.

I’m not saying to not use it, what I am saying is save up and get a better one.
