The Corsair AX860i Digital ATX 860W Power Supply powers your computer system via a single rail and fully modular cables. It has been certified with an 80 PLUS Platinum rating that can save you money by paying less energy bills. You can monitor and control the AX860i with free downloadable software and connecting it to your USB header on the motherboard. With the Corsair Link Dashboard software, you can view its efficiency, fan speed, and more. To help build a quiet PC, Corsair has equipped this power supply with a fan that doesn't spin at low loads.
Put the AX860i under your control by connecting it directly to a USB header on your motherboard with the included cable or to an optional Corsair Link Commander. You can then download the free Corsair Link Dashboard software to monitor the power supply and make changes. With the Corsair Link software, you can view the power input and output, efficiency, fan speed, and internal temperature of the power supply. Additionally, you can set up and modify fan speed profiles as well as choose virtual "single-rail" or "multi-rail" software modes with selectable OCP points.
80 PLUS Platinum
Having an 80 PLUS Platinum certification means less wasted power and excess heat. This reduction can reduce the strain on your other components and save you money over the long run in the form of lower energy bills.
Quiet Operation at Low Loads
While operating during low loads, the thermally controlled fan doesn't spin, which makes it suitable for building a quiet PC.
Fully Modular Cables
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 also energy efficient.
