This isn't a new issue, I actually noticed this about 2-ish months ago. I know my PSU makes a constant buzzing sound regardless of load, probably coil whine, but it also makes a feint buzzing even when powered off. Now I've read this is normal because power is still going into the PSU, but should it be doing it even when the switch is turned off? It only stops if I unplug the power cable.
It's an RM750x btw.
