[SOLVED] PSU Squeaking Noise

[rapola]

My Cooler Master ELITE 550 ver.3 is producing a squeaking noise. It doesn't matter if the system is on or off. As long as the PSU switch is on, it'll make the noise. In the video, my system is off and you can hear me switching the PSU on and off. Should I be concerned? Thanks.

Sounds like coil whine. Likely not harmful.

Coil Whine is the least of your worries with that PSU. Look below.

You're lucky that PSU didn't catch fire yet.
