Weird sound from MK3 Power Supply

Oct 13, 2018 10:36 am

So while I am not new to electronics, computers and the various related bits, I am still new to 3D printing.

And I've noticed my recently purchased prusa MK3 (kit) power supply is giving off a rather weird low sound that I can't quite place in what it might be, I would say it sounds like to bearings running against each other, I've recorded the sound with my phone and amplified it by 15db for easier noticing on full range speakers, and I still can't place it. So that has left me wondering about the state of my power supply?

Does anyone have any similar experience?
