My Be Quiet 850W PSU which has recently started to make an extremely annoying high pitch noise. Its a constant tone and doesnt sound mechanical so i can only guess that its capacitor squeal or somthing similar?

Anything i can do to fix it or should i just RMA it? Is this sort of thing even a valid reason to return it as it works perfectly otherwise. I just wish it would live up to its name and be bloody quiet!
 
Yeah sounds like capacitor whine. I'm not sure if it's a valid reason for an RMA. Nothing a ticket to the manufacturer won't solve though :)
 
I may just buy a new one and keep this one for future trouble shooting should i need it. If i do send it off, then i'd be without a PC untill it was replaced which is gonna be a pain.

Any reccomendations?
