My PSU (no 80-plus cert.) has been whining for a couple of months now and 3 days ago scared the crap out of me when I walked in my room and there was a disturbing stench in the air. Amongst other things, I eventually thought the caps had started leaking... Since the computer was on stand by, I woke it up and everything was normal. Still, I opened the computer up and took the thing out. Normal. No bulging caps, no leaking. Some dust, but nothing serious. So I plugged it up again, voltages were normal, everything was fine. The whining was still there. Great. According to what I've read, LC-Power PSUs usually have Huntkey internals (I know, bad rep. They're actually fine if you keep the load ~50W below the advertised). Not sure if mine is the case. When I bought this PSU, I already knew that I would have to replace the caps in it eventually, but 4 years have passed and the thing never gave me a reason to rush to the electronics store....except the recent whining. Do you guys know anything about Nicon caps and their reliability? I've never seen or heard about Nicon caps and can't find info on them with the exception that they're made in China... The whining is low-pitched, although more noticeable while the computer is running a game (or anything that taxes my 5770). It is also there when the computer is off, but barely audible. Yanking the cord (so to speak) for a while and then plugging it on again results in no whining until I power the pc on. This leads me to believe the whining comes from the secondary side. I can't tell if it comes from caps or coils (although some coils on the secondary side lack glue on them). Should I waste any time on it or just go for a new PSU? I'm looking at a XFX Core 550W. Best I can afford, atm.
