Corsair AX860i 860W Power Supply Review

Installation & Testing
Getting the AX860i installed in your system is very easy. Since the unit is completely modular you use only the cables that you need. When installing make sure you connect the unit to the Corsair Link module, then connect to an available USB header on your motherboard. We did not have any issues installing the power supply in our Cooler Master Cosmos II Case.

We will be testing the AX860i in our Intel X79 system, which is comprised of the following components.

Processor: Intel Core i7-3820
Motherboard: ASUS P9X79 Pro
Video Card: EVGA GeForce GTX 680
Memory: 16GB Kingston 10th Anniversary
Power: Fractal Design Tesla R2 650W
Storage: Corsair AX860i 860W
Cooling: Noctua NH-L12
Case: Cooler Master Cosmos II with 5 fans

We will be using OCCT to test this power supply. Initial spot check on the 3.3V, 5V and 12V rails were 3.28V, 5.04V and 12.1V respectively. We will be running OCCT’s power supply test for 1 hour to stress test the power supply. Below are the results.

As you can see all rails except the 3.3V were very solid during the test. This shows you how stable the digital control is. While the 3.3V did show the only “ripple” it was only a fluctuation of 0.02V.

This is my first time working with Corsair’s Link software. I was actually quite impressed with it. I’ve seen so many different system monitoring programs that are just not done correctly. The Corsair Link software on the other hand is done extremely well. Even without Corsair link connected products we can monitor many different components in our system. Now with the power supply and connected link module there is even more information. We can see effeciency, power in, power out, voltages, fan speed and temperatures. We can also enable multi-rail mode easily on the PCIe connections.
