Unprecedented Power Protection

The Corsair Professional Series Gold power supply pushes the state of the art for reliable delivery of clean power under imperfect conditions. If you require mission-critical stability or you simply want one of the best power supplies available, the Professional Series Gold is for you.

A Fully Modular Cabling System

All cables detach from the power supply. During installation, this gives you the flexibility of using only the cables you need for a clean system build with optimal airflow. And, when it's time to replace or upgrade your power supply, it can be removed from your system without interfering with your cabling — the cables stay in place and connect to your new fully-modular Corsair power supply.

Incredible Efficiency

With 90% efficiency at 50% load, the Corsair Professional Series Gold power supply runs quieter, generates minimal excess heat, and saves you money every month. It's earned the 80 Plus® Gold seal of approval, your guarantee that you're making the right choice for smart,efficient power delivery.

Corsair Professional Series Gold AX850 features:

  • Supports the latest ATX12V v2.31 and EPS 2.92 standards and is backward compatible with ATX12V 2.2 and ATX12V 2.01 systems
  • An ultra-quiet 120mm double ball-bearing fan delivers excellent airflow at an exceptionally low noise level by varying fan speed in response to temperature
  • 80 Plus Gold certified to deliver at least 90% efficiency at 50% load
  • Active Power Factor Correction (PFC) with PF value of 0.99
  • Universal AC input from 90~264V
    • No more hassle of flipping that tiny red switch to select  the voltage input!
  • A dedicated single +12V rail offers maximum compatibility with the latest components
  • Over-voltage and over-current protection, under-voltage protection, and short circuit protection provide maximum safety to your critical system components
  • High-quality Japanese capacitors provide uncompromised performance and reliability
  • Completely modular cable system allows you to use only the cables you need
    • Power supply upgrade and replacement is easy, as the cables only need to be disconnected at the power supply
  • Low-profile, flat cable design reduces air friction and helps maximize airflow through your computer's chassis
  • A seven year warranty and lifetime access to Corsair's legendary technical support and customer service
  • Dimensions: 150mm(W) x 86mm(H) x 160mm(L)

Pros

Quite
Modular
reliable
Cons
None
Summary
Does exactly what it needs to. Comes with many cables for most types of connections the fan is not noticeable. Modular is the way to go for cable management.

Experience: 6 Months

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
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

Quiet, reliable, affordable
Cons
none
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.

Pros

Awesome PSU, over two years of use and still going strong!!
Cons
none
Summary
Killer PSU. I have put this modular power supply through a lot of abuse and use and it is still kicking strong!! Probably the best power supply I have ever purchased. Thanks NCIX!

Pros

Good quality of power supply and cables
Good for SLI system
Very quiet
Fair price
Cons
NONE
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. (My case is Cooler master HAF XM)

Experience: 2 Years

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.
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!

Cons
Mot really
Summary
Want a small body power supply but still able to run my HD6970 crossfire to replace my Silverstone D850. The DA850 is a great psu but for my project a need the smallest 850w.
And the AX850 being a 80+ Gold make it even better n 169$

So i really like it !

I got this at a good price with PM, and with that I was extremely happy. Otherwise the unit is very well build and the cables are good. It powers everything, so I can't complain!

Pros

Capable PSU
Decent price
Modular PSU
Lots of cables!
Cons
none
Summary
Great PSU for a great price. You can't go wrong with Corsair's PSU product line. Would of went for the 1200AX, but I wasn't that trigger happy.

850W is more than you'll ever need (relatively speaking of-course)

Comment: "We expected to feel let down by the AX850 after our great experience with the AX1200 but in the end we were equally impressed by the lower specification model. In fact in some respects, such as the cooling fan performance, it is more impressive than the high end unit. Corsairs exceptional range of

Comment: Computer power supplies have come a long way in just the last couple of years. With the implementation of resonant mode topologies and DC to DC converters for non-primary DC output, we've seen efficiency increase more and more. The AX850 is an example of how to implement these features as effect
