Hello, I'm having this little humming coming straight from my psu, a Corsair HX850W, couple of months old.. it's unnoticeable when playing games or music, and even when there's silence in the room with just the fans spinning, I have to get my ear close to it (at the psu) in order to hear it, but it's there, even when the PC is turned off with just the power cable connected (i.e. just the mobo's light on), and when I turn on the PC the noise increases a bit. I took it out of the case in order to find out if it was the psu itself making the humming and actually it is. Any of you knows if this buzzing is "normal" for a psu or it should be completely silent apart from the fan noise?
p.s. I don't remember if it was there from the beginning cos as I said it is 2 months old but I started noticing this problem just since a week or two.
Any help would be really appreciated, thanks in advance.
