I think a lot of people tend to overlook the power supply because it isn't that glamorous, but I think it's one of the most important parts. So I wanted to get a very high quality one that I knew I could rely on. After looking into it I found that the new Corsair AX series was based on the Seagate KM3 platform which is a solid improvement over their old KM2, which was already pretty good to start with. That plus the modular design and platinum efficiency rating made it my top pick. I was going to go with the 760 since that would have provided me with more than enough power, even if I was going to run a second GPU but the 860 came up on sale so I got it instead.

More than what I need, just got it for the platinum efficiency and because it's from corsair.

Great efficiency, Japanese capacitors, full modular with a nice black cable set.

This PSU is only 160mm in length making it one of the smallest PSUs with 850W of power. If you are cramming a couple AMD video cards into a small case, this may be the PSU you are looking for.

If you are getting your cables sleeved you may want to go with the AX860i as it doesn't use the 18+10 motherboard connection this PSU has. The extra money you spend getting the i would be saved on that cable.

No noise, no coil whine, 4 stars because they do not send labels which can be disastrous, imagine plugging in the wrong wire in the wrong socket.

Amazing power supply. 10/10 ~ IGN.

No problems at all, besides the custom white cables are extremely stiff and a little difficult to work with.

The fanless operation is the feature that sold me on this model, however, the coil whine is incredibly loud. If you need silent, I would suggest getting a different model or brand. Other than the coil whine the unit runs perfectly, and the cables are neatly bundled but a little on the short side for my liking.

If you have the money spend it on a great PSU like this one. In my build it stays totally silent even while 3D Mark. The cables are also very nice.
