As the title says, my NZXT 750W power supply is buzzing pretty loudly and vibrating my computer's case and also my room's floor basically, while i'm playing Overwatch, osu! or any other game. (no i'm not a weeb)
I've read that there might be something with a coil or something like that, but i don't know anything about electricity or anything in that domain, basically. So should i worry or nah?
I just bought a G4560, a new mobo and some HyperX Fury RAM and i don't want to spend money on a new psu aswell.
Should i be worried or just not give a flying fk?

In the worst case scenario, what could happen?
