Buzz sound when UPS is activated

Whenever the electricity goes out and i am wearing headphones connected to my PC i can hear a buzzing sound, and if i use the mic the  people on the receiving end can't understand what i am saying.

now this is onlythe case when the power source to the PC is from the UPS since the electricity is out, but i am wondering why is this the case and if this won't destroy my electronics connected to the UPS(pc, monitor, modem).

Should i replace my UPS ?

Re: Buzz sound when UPS is activated

Your ups is fine
