5.2 Connectors - REQUIRED
5.2.1 AC Connector
The AC input receptacle must be an IEC 320 type or equivalent. In lieu of a dedicated
switch, the IEC 320 receptacle may be considered the mains disconnect.
5.2.2 DC Connectors
Table 5-1: Main Power Connector Pin-Out shows pin outs and profiles for typical
power supply DC harness connectors. The power supply requires an additional two-
pin, power connector.
UL Listed or recognized component appliance wiring material rated min 85 °C, 300
VDC shall be used for all output wiring.
There are no specific requirements for output wire harness lengths, as these are
largely a function of the intended end-use chassis, motherboard, and peripherals.
Ideally, wires should be short to minimize electrical/airflow impedance and simplify
manufacturing, yet they should be long enough to make all necessary connections
without any wire tension (which can cause disconnections during shipping and
handling). The recommended minimum harness lengths for general-use power
supplies is 150 mm for all wire harnesses. Measurements are made from the exit port
of the power supply case to the wire side of the first connector on the harness.

pin 12V2 connector.
