Apologies for not making it so clear, edited original post as such to better specify. My question concerns on how the PSU does the buzzing noise when the PC is off but the PSU is on (I thought this state was called standby, correct me if I'm wrong). I was wondering if that was normal for the PSU to keep buzzing like that (I know technically it's still "on", but from other manufactuer PSUs such as EVGA, I've never heard these noises before when the PSU is on but the PC is off. I unplugged my usb headers and such to see if anything connected was the issue, and the noise seems to still persist. Hopefully that makes it more clear.
That being said, the information about how plugging in different powered devices can actually make your PSU more audible was interesting. I’ll definitely keep a mental note on that.
