Product Info

The World's First Enthusiast Grade Digital ATX Power Supply

Digitally Controlled Power
The fully modular Corsair AX1200i uses a Digital Signal Processor (DSP) for tighter voltage regulation, which improves overall system stability, and increases performance to 80 PLUS® Platinum levels. Built-in Corsair Link™ gives you unprecedented monitoring and control.

Quiet, Efficient Operation
Upgrading to digital provides increased efficiency. The AX1200i is certified 80 PLUS® Platinum, which results in lower heat generation and a quieter fan profile. The AX1200i is so efficient that the 140mm fan doesn't even spin at low loads for completely noiseless power delivery.

The built-in Corsair Link™ functionality allows you to know how well your AX1200i is working at any given moment and lets you quickly tweak its performance. Server-inspired diagnostic tools monitor real-time efficiency, power usage, configurable over-current protection points and fan profiles.


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™ 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.
