Like how it looks. Works totally silent when idle or loaded with CPU,RAM, integrated video stress tests. BUT! When I installed Gigabyte 1070 G1 this power supply started whining when under test with Heaven benchmark or during the games. Maybe its just bad luck with this one, but anyway - not happy, replacing it with some other brand.

No issues with it so far. It works as expected.

Works nice, only issue i've had is when i switched gpu's to the gtx 1070, it started to whine under load.

A bit of a tricky thing getting it into the psu shroud. Had to remove foam inserts from the case for it to fit, but once bolted in, it doesn't move a bit. Cables were easily managed and hidden behind back panel. Fan is virtually silent.
