Loud humming noise from my central circuit breakers when printing

I'm not sure if I got a defected PSU or not but every time I'm printing, my house central circuit breakers start to hum very loudly. What do I need to do get this problem resolve or I need to get a new PSU?

Does another appliance in the same socket work without humming? I mean electric kettle or clothes iron or something similar. The problem could be in circuit breaker itself.

Nope. As stated, it only hum when the printer is printing not at idle.

Do you have a UPS you can put between the MK2 and the wall socket to see if that makes a difference?

I will have to buy one to try that out. I'll let you know the result.

Looks like there's interference at the wall socket. After moving it to another one (diff location in my house), the problem stops.
