Tons of power for high end video cards

Eric L. Fletcher, Amazon
2 July 2013
  • 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.

Solid

Jeremy Holmes, Amazon
18 December 2012
  • 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.

Small but powerful

Jeremy, Amazon
2 December 2012
  • Summary: I've been running this PSU for about a week now. I'm very happy. Pro's This PSU looks great with my build, fits perfectly in the case, and leaves me plenty of headroom to add a second GPU in Crossfire at a later date. The modular design makes for cleaner cable management or easy replacement if you want to get the fancy individually braided cables form Corsair. According to my APC UPS the unit is only drawing about 120W at idle.

Best power supply in it's class!

Steven, Amazon
1 November 2012
  • Summary: This power supply delivers very clean, steady, high amperage power for cheap, and does it reliably while I'm working on my 3D renders. I'm a 3D artist, and also play demanding games on the side when I have time, and even when my GTX 580 and my Overclocked 130W CPU are running maxed out for weeks at a time rendering stills and animations this thing does not break a sweat.

Outstanding.

Dave, Amazon
22 September 2012
  • Summary: I have this power supply powering an Asus P9x79 motherboard with a 3930K CPU, a single Gigabyte NVIDIA GTX 670 OC graphics card, 32 GB Kingston RAM, four fans including a Coolermaster TPC 812 heatsink, 2 SSD's(Crucial and Force 3 GT) and 2 optical drives in a stock, non overclocked system in a Corsair 550D case. The PSU just "loafs" with this system, and its own fan NEVER comes on, even during 3D work in Photoshop.

A Great Power Supply

zr1tom, Amazon
3 March 2012
  • Summary: I purchased this new Corsair AX 850 power supply (PSU) from Amazon and its performance is nothing short of "OUSTSTANDING". I am very pleased with its operation; my computer has an endless supply of clean power. The unit itself is rather large. My original 300 watt PSU is 1/2 inch shorter than the Corsair AX 850 PSU, thus the Corsair is a tight fit in my microcomputer case.

It's a high-end power supply

D. Vang, Amazon
2 February 2012
  • Summary: It's a high-end power supply. You get what you pay for. I got this to replace my OCZ 750 modular unit that keeps whining since day one. I now avoid OCZ whenever possible because of their bad RAM from another build and now the PSU. Corsair RAM and PSU replacement seems good so far.

Just buy it already!

freeman, Amazon
21 January 2012
  • Summary: This PSU is simply the best 850 watt you can buy. I have it running two Sapphire 6950's in Crossfire, and it doesn't even break a sweat. High efficiency, runs cool and quiet, and enough power to last years. What could you ask for it? Just buy it!

You get what you paid for.

Aliened, Amazon
30 September 2011
  • Summary: This is a great PSU, yes a little expensive, but is worth it. I don't know why a lot of builders choose to spend as little as possible when coming to the PSU, for me that's one of the worst decisions you can make. Why? because by choosing a bad PSU you are risking your other hardware from getting a electric discharge, or something of that sort. Then, because of trying to save a couple of bucks, now you'll have to replace some more expensive hardware.
