    Being fully modular made my cable managent easy as ever hide. Great build quality and great certification level, so I know my pc parts are in good hands.

    If you are looking for a quiet power supply this is the one. I choosed the 850w so the fan almost never spin! Very satisfied.

    The product is easy to install. For 850 watts It worth the price. It doesnt make any sound to my knowledge and the power usage Is enough to last a good 3 years.

    Well, I ordered this power Supply for a new pc build. I waited until I had all the components, but by the time I went to turn on the PC.. Nothing... After some trouble shooting I discovered this brand new Power supply was a dud....

    Was looking for a quiet 800 Watt PSU and this was the one. Also slightly smaller than expected! 10/10

    Very silent. And being modular is a great thing. You only attach the necessary cables and no more messy unused cables! The fan doesnt turn on unless theres a high CPU/GPU load. In fact, my case is very well ventilated so Ive never seen the power fan kick in at all.
