Now using for 2 weeks and it is as advertised. Super silent for most of time. It has 0 rpm fan mode. So practically no noise at all. Fan kicks in at 40% load. And being modular has its full advantage in using only those cables required. With 80% gold certified rating, no question on performance.

The only cons I can see is that it really made big hole in my pocket. But as usual for best product it seems pretty worth. So overall very satisfied.
