The 2018 model of the RM650x was released around the time I was purchasing a PSU, and it was actually cheaper than the last model. This thing is very sleek looking with the all black cables and body. And it even comes with a 0 RPM mode when components in the computer aren't demanding much power. But even if the fan is spinning, I was never able to and actually still haven't heard it.

Silent most of the time and the build quality and packaging is very nice.

A fully modular PSU with zero fan mode. A reliable model according to reviews.

I haven't had any problems with this PSU. It works great and it is very reliable.

A bit bigger than I should have got for my H200 case, but gets the job done well.
