AX1200i Digital ATX Power Supply — 1200 Watt 80 PLUS® Platinum Certified Fully-Modular PSU

Corsair AX1200i Digital ATX PSU: complete digital control

The revolutionary AX1200i is the first desktop PC power supply to use digital (DSP) control and Corsair Link (learn how to use Corsair Link with AXi Series PSUs) to bring you an unprecedented level of monitoring and performance customization. The DSP in the AX1200i makes on-the-fly adjustments for incredibly tight voltage regulation, 80 PLUS® Platinum Efficiency, and clean, stable power.

Real-time monitoring and control with Corsair Link

Put the AX1200i under your control by connecting it directly to a USB header on your motherboard with the included cable, or to a Corsair Link Commander (available separately). Then, download the free Corsair Link Dashboard software for unrivaled power supply monitoring and control options.

Monitor power input and output, efficiency, fan speed, and internal temperature, directly from the Windows based application. Or, take it to the next level and set up and modify fan speed profiles, or even select from virtual “single rail” or “multi-rail” software modes, with selectable OCP points.

Stable and Reliable Power Delivery

DSP-controlled, real-time voltage regulation helps ensure that your valuable components receive clean, stable power.

Less Heat and Lower Operating Cost

AX1200i's extreme efficiency earns it coveted 80 PLUS® Platinum certification. Less wasted power means minimal excess heat. This can reduce the strain on your other components, and it can save you money over the long run in the form of lower power bills.

Quiet Operation at low loads

Super-high efficiency has another benefit: silence. The thermally-controlled fan doesn't even spin at low loads. It's ideal if you're building a quiet PC or you just want to reduce the amount of ambient noise in your life.

Easy installation and cable routing, with better airflow

The fully modular cable set allows you to use only the cables you need, and the flat design makes cable routing much easier in tight spaces. You get a clean-looking system build with cables out of the airflow path for efficient space usage that's energy efficient as well.


The fully modular layout allows you to use only the cables you need, and the Self Test button makes it easy to check the status of your PSU.

Using a AXi Series PSU and Corsair Link's "power" tab with different configurations to determine power usage during different tasks

By Jonny Gerow, on May 31st, 2013

I was curious as to how much power my gaming PC uses with one, two and three graphics cards installed and how that compared to using the integrated graphics of my Intel® Core™ i5 CPU. Corsair Link and my Corsair AX Series Digital ATX PSU helped me determine that! In this blog entry, I show how much power my PC uses with the different configurations.

Right now I have a Core i5-3570K running at 3.4GHz and three Gigabyte GTX670 2GB cards each running at 980MHz.

Currently, I'm just sitting here typing this while listening to music streaming on Pandora. Not a lot going on, so I'm seeing what sums up to a whole lot of nothing going on within Corsair Link. I'm pulling 224.9W from the wall, which is still a lot... but that's primarily because I'm keeping three graphics cards powered even though I'm not using them. Spoiler: We'll see that number lower as I take cards out of the system, even sitting here doing a whole lot of nothing.

Haswell compatibility with Corsair power supplies

By Jonny Gerow, on May 9th, 2013

A report recently published over at the VR-Zone discussing the new 4th generation Intel Core processors, code-named "Haswell", and their ability to go into a lower power sleep state than any previous processor has caused some concern about PSU compatability with the new processor.

When an Intel Core (i3, i5, i7) processor is idle, it goes into a sleep state that requires less power than when the CPU is active. Since the motherboard voltage regulation modules that provide power to the CPU gets their power from the power supply's +12V rail, these sleep states can dramatically reduce the load on the power supply's +12V rail.

Corsair Link Lighting Node

By Jeff Checchi, on May 2nd, 2013

The Corsair Link Lighting Node is a component that comes with our Corsair Link Cooling and Lighting Kit, but many people do not know that can be used independently, without other Corsair Link components. The Lighting Node offers quick and easy lighting control for your system, and comes with everything you need to light up the inside of your case in a color of your choice. If you want to have more advanced functionality and control over the Lighting Node, there are some ways of linking it up with other hardware components, but first let's talk about the stand alone functionality of the Corsair Link Lighting Node.

Corsair H50s in Clash of the Titans

By Mike Clements, on April 30th, 2013

NVIDIA has unleashed a Titan among us mortals. The new NVIDIA GTX Titan GPU offers amazing graphics processing power while consuming up to 250w of power. The stock cooling setup on these cards looks pretty impressive but of course, there are always people out there that are not content with stock.

Recently, I stumbled across a system build thread over at the EVGA forums. Member "dustingg" has taken two Hydro Series H50 CPU coolers and with some slight tubing modifications, he's attained cooling results rivaling much more expensive custom cooling solutions. We applaud dustingg for his ingenuity and we also really like his choice of PSUs.
