cx750 PSU buzzing noise

[InoF]

I recently noticed my Corsair RX750 making some buzzing noise and i was wondering is this is normal? It is pretty loud since i can hear it from where i sit about 90cm away from it and also it is a constant buzzing sound, as long as power is being supplied to the psu it is making said noise, only way to make the sound go away is by flipping the switch off on the psu. Can this potentially be dangerous to my system or is some buzzing on psu's normal as it is for coil whine on gpu's?

its just coil whine, its not necessarily bad but if its annoying could try rma.

if it is indeed coming from psu even under no load, replace it
