The coil whine is so bad that it's almost as loud as my GTX 1080 with the fan at 85%

Swapped it for a EVGA 750 GQ and zero coil whine

Still working great and replaces my old PSU that was having bad coil whine issue.

Caused an annoying amount of coil whine when under high stress/FPS

As for the PS itself, this is a rig that needed fewer than 300W, so this ran in fanless mode, had no noticeable coil whine at these loads and should be fine.

Didn't notice any coil whine.

Severe coil whine began after only one week of use

It has a higher wattage than my old power supply, but apparently that doesn't mean anything, seeing as though this unit randomly stops working during game play, has a squealing fan, and loud coil whine

Only con is that there is high pitched coil whine when it's running, though I can't hear it over the sound of the fans.
