Does that power supply makes a buzzing noise or hums when it turns it on? That's my biggest concerns.

I only run one set. Of lights to one transformer and have never heard any noise. Try reducing the number of light lengths to each transformer. I think they recommend only three to a transformer.

Mine does not make noise. If you put it against your ear there is a faint buzz. But nothing to be alarmed about or a nuisance to use.

Technically if it is plugged in it is always on. But after months having it constantly on i have yet to hear any buzzing noise or hum.

we are not using it to power audio equipment so i do not know if it will produce a hum in your equipment the unit itself is quiet I know some supplies do hum but the one we have is quiet

I love my thermaltake power supply. I don't get any loud noises from it at all. There's no humming. Only the fan makes the wind noice but low level. I will buy another one for another build when I'm ready.

I've purchased PSU's by corsair for years. Their older PSU's did not have a lot of issues until the past year or so. Since then, I've noticed a familiar trend of people seeing the same issues with a strange oscillation (high pitch noise) coming from them. Lately, I usually purchase PC Power & Cooling PSU's, and recently one of these EVGA units for a recent build. So far, the EVGA PSU hasn't given us any issues. I'd bet they're decent enough. Mine went into a workstation build with no problems to speak of to date. :)

You know I had to go and check! However, I have an 828LM and no hum whatsoever. Have you unplugged (the replugged) the unit and tested it away from other equipment for this humming noise?

There is a little bit of noise when I warm mine up but it is not that loud, I would describe it as a very soft humming.

yes, when it's running it will make a humming noise, sometime with a vibration.

I didn't notice any unusual Buzz when I first powered up the unit in my shop. My opinion is is the noise level is normal....

At high power levels there is a hum. At lower levels there is little or no noise.

No noise or hum - I forget it's even there unless it's doing it's self test (about 5 seconds) then it's quiet again. South Florida.. we have lots of power interruptions and it's been a blessing.. I know it has saved my computer time and again.

The only noise you should hear is the drive spinning, I wouldn't classify that as a buzzing noise. There really shouldn't be any noticeable noise at all!! I've had for over two years and have used in some rough environments, no issues at all!

Mine is definitely silent. It only buzzes/clicks when there is a power fluctuation, which is very rare. I'd suggest to check your line voltage at the outlet before condemning the unit. If that's ok, then yes, your unit may be faulty.

It can be noisy; you can manually set the speed via the speed control knob on the back of the unit. When set at max yes, it is VERY loud. At its lowest it does create a low hum. Temps only decreased maybe 1-3C, during heavy system load it kept my GTX 670 reference card at a nice 57-60C.

Not exactly in that condition but yes I have. For example when running a game but just in specific parts of the game like in the menu or something. I think the buzzing comes from the fans but not really sure.

mine doesn't hum. I wish I could help. Maybe it is the model. I had one, that i loved, and one day, it just quit working. They didn't make that model anymore, and I had to cut the plug, and send it to them, and then they sent me the most similiar model. But I really loved my old one. It was beautiful. This one works great, but is not as aesthetically pleasing to the eye. :-(

The fan on ours goes off often, but no, no buzzing. Is it still under warrantee? We had to use our warranty, and although lengthy, the customer service was able to (fina;;y) help us.

I have been using the this drive for several months and I have had no buzzing noises. I would be concerned about that. Sounds like there may be an issue with the drive. I had one of the book drives start dropping out like it was getting disconnected then it finally just died. I had it for about 4 years before this happened though and had already purchased another one a couple of months before the old one died. The one I have now seems to be working fine but I am not sure I would buy another one.
