From the Manufacturer:

This power supply, unlike the standard ATX, has two additional connectors sometimes designated as P8 and P9. Each connector contains 6 wires and connects to the mainboard end to end forming one long row of 12 wires. These units are used in many applications including computers, voice mail systems, CNC and other industrial control systems, and medical equipment. It is powered on by a switch that is connected to the power supply by a four conductor electrical cable.
