Product Info

Corsair AXi Digital ATX PSU Gives You Complete Digital Control

The revolutionary AXi Series PSUs are the first desktop PC power supplies to use digital (DSP) control and Corsair Link to bring you an unprecedented level of monitoring and performance customization. The DSP in the AX860i 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 AX860i 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
AX860i'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.

Additional Features

An ultra-quiet, 140mm double ball-bearing fan delivers excellent airflow with exceptionally low noise levels by varying fan speed in response to temperature.

The AX860i is so efficient that the fan doesn't spin up until you're pushing your system hard. And, fan speed thresholds can be adjusted with Corsair Link.

Are you used to checking to see if the fan spins to verify if your power supply is working? No worries. AX860i has a self-test switch to verify proper functionality before you install.
