Hey guys,

I've had this PSU almost 2 years now and it's been great since. I turned my computer on the other day and heard a strange buzzing sound. I disregarded it for a few days, but it has gotten to a point where I have to adress it.

I narrowed the noise down to the PSU, so after I turned off my computer, I flipped the switch on the back to off. The sound is faint, but still there. I disconnect the cord, then it's gone. I tried plugging it into a different outlet, and still get the same noise.

It sounds exactly like a buzzing wire, only that it's really loud. Don't know what this could mean, but should I RMA?

Also to anyone that has RMA'd through Corsair before, am I receiving the exact same model, but refurbished? Do I have to take all the cables out and send it with the power supply? They're currently closed so I can't ask.

Oh, and I suppose the biggest question is, should I not use the computer? Not sure if this is a sign of PSU failure, but after a turn off my computer, my speakers make this really weird almost 8-bit sounding noise. I have a sound card and it never has done that before.


Thank you!
 
That sounds like you have voltage on your ground. It might be a house wiring fault. Is this into a surge strip or UPS?
 
Sruge strip (even the strip is buzzing faintly), but I tried plugging it into another wall outlet and the noise persists.

Could it be dust, causing a component to short? A friend told me it might be that.

But can I still use my computer regularly? I'm not harming it by using it now right?
 
IF there is a grounding issue, then no matter where you plug inside the house, it's going to do it. You'd have to try someone elses house/circuit.

The only thing that's not disconnected when you flip the rear switch, is the ground wire. Since that's the only remaining electrical connection, I'd bet that's where your noise is coming from.
 
i just noticed my hx850 buzzing too all of a sudden and my surge protector buzzing as well. some have mentioned to get a battery APC to filter and make sure you have "clean" power and see if the noise goes away. might have to try it..
