The AX860i strongly resembles the larger AX1200i, with the only difference being that the length of the chassis has now been reduced to the ATX standard 160mm, allowing the AX860i to fit inside smaller ATX compatible cases. This is especially a problem with desktop HTPC cases, where the PSU compartment area is usually limited. The chassis of the power supply is sprayed with a matte black paint, as with the majority of Corsair's power supplies.
As with all of Corsair's power supplies, the sides of the unit are being decorated with stickers placed in a slightly embossed area of the chassis. The stickers are glossy black and feature only the company and model logos.
We found the sticker with the electrical specifications of the AX860i on the top side of the chassis, covering about half of the unit's top side surface. This sticker will only be visible if the power supply is placed towards the bottom of a tower case and with its fan facing down.
The rear side of the AX860i is entirely perforated, allowing warm air to escape towards the rear side of the case. Besides the standard on/off switch and the typical A/C power plug, Corsair also placed a small sticker with the unit's logo on the rear side of the power supply.
This is a fully modular power supply and so 15 connectors for the modular cables can be found at the front side of the unit. Interestingly, the PCIe and CPU connectors share the same plugs, as well as the SATA and Molex connectors. There is also a self-test button with a green LED next to it, allowing the user to quickly diagnose if there are problems with their power system. The self-test button checks all of the voltage rails and the fan of the power supply, ensuring that everything works the way it should.
