Out of the box, the AX860 has one of the best selections of cables and connectors of nearly any power supply available. It offers dual ATX 4+4 cables, short and long SATA cables, and even PCI-E cables in both single and dual connector varieties. As far as the number of connectors go, there are six PCI-E connectors, 12 SATA connectors, eight Molex and two Molex to FDD connectors.
Rail distribution is as simple as it gets with a single 12V rail. There is no need to worry about load balancing here.
A Look Inside
Opening things up reveals why there is only a 120mm fan cooling the unit. First, there is plenty of passive cooling going on inside the AX860. On top of that, the daughterboard that breaks out to the modular connectors shortens the depth of space on the inside that would normally allow for a 140mm fan to fit.
A pair of Nippon Chemi-Con bulk capacitor sits on the primary side of the power supply.
The secondary side is littered with a bunch of Nippon Chemi-Con caps.
