Tons of power for high end video cards

Summary: I used this to replace a lower wattage 3 year old Seasonic power supply. Installation was pretty straightfoward, except for the fact that it did not like the cables that came with the Seasonic. The plugs were just different enough that they would not work. That was rather irritating. Not sure if that's Seasonics fault or Corsairs though. But it puts out tons of power and is quiet enough, even under load.
Summary: Had this for 6 months running an i7 3770k overclocked to 4.5Ghz and running 2 GTX 660s in SLI. It's still pumping juice into my rig very well and doesn't waste power by having the fan on un-necessarily. Great PSU!
Pros: - Fully modular, - Clean cable sleeves, - You can buy individual sleeved cables in different colors off the Corsair website!, - Fan only goes on when needed
Cons: - A little bit on the pricey side, but for what you get, it's worth it!
Summary: Awesome PSU. Very easy to install and easy to keep things looking neat and tidy. Plenty of power for everything and then some, it's definitely the best 850w power supply in my experience. It's quiet and runs perfectly well, would definitely recommend.
Summary: 1.This PS is for people who want to DIY the cables. It's a good idea not to make the case messy. Corsair makes a good product again! 2.I have 2 GTX670's (which beat 1 GTX690), and 850 gives me enough power to run the whole system. You don't need to worry about the length of cables, they are long enough to be connected with your MB.
Pros: Good quality of power supply and cables, Good for SLI system, Very quiet, Fair price
Summary: This has been the best PSU I have ever owned. The only complaint I have with it is how some of the cables have 2 cables going into 1 pin hole, or are split between two other connectors. Which makes it very difficult to make your cables flat and straight. Even so, I was able to mod the cables fairly easy to be individually sleeved. As long as Corsair continues to build these PSU's I will continue to use them in my builds.
Pros: Small form factor, Quiet, Fully modular
Cons: Some of the modular cable designs are not the best.
Summary: This thing is solid. For most people, power supplies aren't like CPU's or video cards. There are no benchmarks to run, no overclocking, tweaks, or other testing to be done. You install it, and it either works or it doesn't, so there's not a lot for me to say. It's quiet, my machine runs cool, and most importantly, it's stable. Love the fact that it's modular. I will never go back to a non-modular PSU.
Summary: I bought my first AX850 a couple years back and it's still going strong. What originally drew me to it back then was the fact that it was an extremely well built single rail design, very efficient, and extremely quiet. I now own a number of these powering a variety of different systems including a dual processor Opteron 6180SE server. If you need a solid 850 watt PSU, look no further!
Pros: Single rail design. Solid power. 80+ Gold efficiency. Fully modular. Very quiet. Seasonic design in Corsair colors.
Cons: If you don't get it on sale, it does feel a bit pricey.
