Absolutely love the low noise

After 5 months it's making a weird noise, like a buzzingEDIT: I flipped my case upside down, while it was on, and back to normal and it fixed the noise

I like the all black cables, and the price, but the noise is a big problem for me.

pretty loud and the fan has already started making squealing noises.

After only two months of use this PSU makes a horribly annoying clicking noise

I tried it with a 350 W unit and it worked fine, just more noise because of the smaller fans

No problems, no weird noises.

It works quietly (I cannot tolerate noise), never glitches; just keeps running

I ordered this power supply over 100w my pc needed, but the fan makes a terrible noise even at idle

After about a week my PC started making loud rattling noises

I had to get a new PSU because my old 520W PSU I bought at Best Buy started showing symptoms of failure - fan makes terrible grinding noise when cold

Quiet, but came with a broken fan which created a horrible noise as soon as I powered on my new computer build.

I bought this PSU as a replacement for my Silverstone SX-500-LG which had an annoying fan rattle noise at low

It produced a pretty audible grinding noise

Thanks Amazon, the noise from my dying power supply was really annoying.

As mentioned by other reviewers, there is an intolerable high pitch noise that arises from the PSU's fan.

The only time you really hear the noise is when it does a power cool down cycle

Works great, low noise

No weird noises from mine.

In an otherwise quiet room the noise is maddening, especially as the PC is right next to me.

However, it did have a faint buzzing noise every now and then, but stopped when I adjusted the PSU in my case

All wired have good length, nice quality, 0 noise, 100% recommended, hopefully my electricity receipt will down since my computers is almost On all day

This doesn't seem to hamper performance, but the noise is quite loud as to where it is beyond tolerabl

Had this unit for two weeks before the fan started making loud noise intermittently

There was a grinding and high pitch squeaking noise from the PSU and would enter a reboot cycle

After 5 months it's making a weird noise, like a buzzingEDIT: I flipped my case upside down, while it was on, and back to normal and it fixed the noise

Then it started making a buzzing rattling noise randomly

The computer issue I was having (graphics card/constant running fan) where the computer would just power off after grinding a loud fan noise for a while-was fixed with this upgrade

Then the fan inside started grinding and making all sorts of awful noise.

While the unit so far has performed just fine, it did after a short while develop a very loud fan noise from the power supply's fan.

Corsair CX500 runs great but when installed with fan taking in air from under the PC (sitting on a desk not carpet) it would get very loud making a terrible noise, after reading some forums it seems many people have this same problem and was recommended to turn the PSU over

Very good voltage regulation, well controlled ripple and noise, runs very cool, managed Bronze efficiency in the hot box

The fan created an audible whirring noise, makes a consistent high pitched noise, and will rev up to 100% fan speed every 5-10 minutes after reaching a unacceptably high temperatures

As of a few month ago, there has been a sickening grinding noise coming from within.

Within 24 hours both power supplies fans were making terrible noise, loud, as if they were breaking

The main problem is this unit gets really HOT if you dont have a great o good air control inside your
