I've had this problem for the past couple weeks which was hard not to notice, whenever I accidentally nudge my PC hard enough (Its on the floor) the power supply begins buzzing, I didn't fret about it before but this time I decided to open up the case and see what component it was and it was clearly the PSU. The only way to fix this is to restart my PC and its all back to normal until another accident, note these are not even hard hits, just little accidental nudges which are most of the time not even near the area where the PSU is. I'd like to know if I should be worried. Thank you.
(The PSU is a Corsair Builder Series CX600 80 Plus Bronze which I put in early 2016)
