zero fan mode is awesome. Has all the power cables I could ever need and then some. Nice to see they finally left the rubber coated wires in the past and started offering some cable combs as well.

Overclocking a modern high end build has posed no issues for this PSU, and it runs very efficiently and silently.

I Haven't put this power supply to the longevity test yet. However, I have loaded it up quite well at this point. It seems to be great so far. It has an adjustable fan and modular cable design is great. It should have all of the cables you may need.

Love modular PSUs for the simple fact you only use the plugs you need and not have extra all over the place, but also leaves room for upgrading, this one will keep me going for a while.

I upgraded most of my PC components about a year and a half ago (Motherboard, Processor, Graphics Card, Memory, PC Case) but reused my old 750 power supply which wasn't fully modular. I decided to get this 850 fully modular power supply for the added flexibility and to have some extra power for my components and it has worked flawlessly so far. Great product!
