Corsair AX860i Digital ATX Platinum Power Supply Review
A Detailed Look
The Corsair AX860i Digital power supply enclosure is painted matte black and is only 160mm (6.25”) deep so it should easily fit into most cases. It uses a single high-quality 120mm fan on the bottom for cooling, instead of the 140mm version used in the AX1200i (even though the AX860i literature describes the fan as being 140mm).
The fan speed is automatically controlled by the internal component temperature (but can optionally be configured through the Corsair Link software) and doesn’t turn on and start spinning until the PSU exceeds ~30% load. Up until that point the AX860i is silent. The dual ball bearing Yate Loon Electronics fan (D12BH-12) is a relatively powerful high-speed fan that has the potential to provide excellent airflow and is rated for 0.30A at 12 VDC.
The back panel includes a heavy duty On-Off switch and AC receptacle along with an open honeycomb grill that allows the exhaust air to exit the power supply with minimal resistance and turbulence.
The front panel incorporates fifteen modular cable connectors, all nicely labeled. The six 6-pin connectors on the left are for the peripheral cables and there are six 8-pin connectors on the right for PCI-E and extra CPU cables. The 24-pin mobo cable uses two connectors. The 4-pin Comm Port connector is where the cable from the Corsair Link USB dongle cable plugs in. Also note the Self-Test push-button and LED indicator in the upper left corner.
Note: The AXi Self Test feature can only be used when the DC output cables are disconnected from the PSU (i.e. before installation). The Self Test feature is disabled once the DC output cables are plugged into the PSU, which means you can't run a self test while the PSU is installed in a PC (unless you disconnect the DC output cables).
The Corsair AX860i Digital power supply comes with a good assortment of all modular cables and connectors. Some of the cables are covered with braided plastic mesh sleeving while others are a flat ribbon-style cable.
The Corsair AX860i package includes six PCI-E connector cables for multiple, high-end graphic card support. Corsair uses the 6+2-pin configuration for added flexibility.
