Corsair AX1200i Digital ATX -1200 Watt 80 Plus Platinum Certified Fully Modular Power Supply

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

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 moni-toring 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 moni-toring and control with Corsair Link

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

Moni-tor 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.
