My PSU is buzzing like it's got a fly in it, if it's not one thing...it's another. =(

I've been dealing with a lot of RMA/return/claim stuff lately and this takes the cake. I searched but found no real conclusive answer to my questions...I'm hoping someone can help.redface.gif

I have a NZXT Hale 90 850w psu, and it's been in my PC for eight months now, often powering the computer on standby and on for lots of the day. Either way, it's not seen much use. I don't even have a GPU.

Just a few minutes ago I hear a buzz that sounds a bit like a fly in the PSU, it fluctuates and is not very consistent. I thought it was some fans that were stuck (not enough power on Low to spin them up) but it continued after I got them going.

When the computer is in standby it becomes quieter but continues. It also continues when the computer is off.

Switching the PSU's main power switch to 'OFF' makes the noise go away (dur).

It is not a "whine", it reminds me of a fly stuck in a spider web, I guess. It is not the fan, as it does it when the motherboard is powered down.


My concern is: I cannot afford my computer being fried by the PSU, but I also need to keep working and dread weeks of delay with an RMA through NZXT. Should I be concerned that this PSU will overload my PC? I have read a few reviews of power supplies doing that, not long after a noise started occurring. One specifically was a NZXT 1000w or 1200w PSU I noticed when I was researching PSU's.

Any advice on the RMA is appreciated as well, as I imagine this will be going back, since it's loud enough to annoy me.

This is the power supply I have:http://www.amazon.com/dp/B003YFIUEQ/ref=pe_175190_21431760_M2T1_ST1_dp_1

More than likely it is the transformer or one or more of the capacitors. I'd be more inclined to say the transformer if its an actual "Buzz" rather than a whine or high pitched squeal.

Noise coming from electronic components is not a guaranteed indication of impending immediate failure, but it can definitely be a sign of trouble.

I had a video card that began squealing and died after about a month. I have a motherboard that squeals every time you power it on, and has been doing so for over a year but still runs. After it warms up the noise stops. I suspect one day the caps will give out and it will finally die.

I have read that some lower quality capacitors can and will make audible noises from day one, but will continue to give good service for many years.

I would probably go ahead and RMA it now. As for that specifically, I am no help, sorry!

I just noticed, the sound sometimes comes through my computer speakers...... mad.gif

I think that might indicate a problem with the noise filters, if it has them..i don't know enough.

Thanks for the quick response, no worries on specific help, not everyone has experience with NZXT. I'm going to see what cross-ship options they have, apparently there's a way to get one shipped out immediately if I give them my credit card information.


EDIT: Yep, I hear it through my speakers, I'm going to shut down the computer and see if the power supply is even polluting my house electricity with electrical noise. Very odd...

I even plugged the speakers into a different outlet via extension cord and unplugged them from my PC.
I wonder if it could be electromagnetic radiation too, or just my power supply messing up my house AC. If the noise goes away when the computer is off, I'll see if I can get the noise to happen with space between the speakers and my PC.

I listened to my audio system and I can hear a similar noise that I'm not sure was there before, and its in my TV too even when off. Could my AC power have caused or be the cause of this? I'm so confused now. it happened all of a sudden too...

I am inclined to think other electrical appliances in the house.

For example, I have energy-saving lightbulbs installed in dimmer sockets where tungsten bulbs used to be.

Even at full brightness setting, this caused my FSP AU-550CM to buzz loudly whenever the lights were switched on. Yes, it sounds like a constant 'tzzzzzzzzzzzzzzzzzzzzzzzzzz' sound.

Before I had the Aurum, all my other PSUs behaved just fine. It was only the 550CM that buzzed incessantly.

My Seasonic M12II 430 as well as numerous other OEM power supplies in prebuilt rigs, and an SFF-sized FSP300-60GLS worked just fine.

now it seems to have died down. Looks like I'll have to do some more troubleshooting before I figure this one out. I submitted a ticket already, do you guys think I should cancel it for now? It sounded like more than just dirty AC power but I just don't know. doh.gif
