13. Main and Auxilliary AT Power Connectors (12-pin & 6-pin PWRCON)

This connector connects to a standard 5 Volt power supply. To connect the leads
from the power supply, ensure first that the power supply is not plugged into an
AC outlet. Most power supplies provide two plugs (P8 and P9), each containing
six wires, two of which are black. An auxilliary connector (P10) is provided in
case the power supplied through the main connectors are insufficient. Orient the
main connectors so that the black wires are located in the middle.

Using a slight angle, align the plastic guide pins on the lead to their receptacles
on the connector. Once aligned, press the lead onto the connector until the lead
locks into place.

14. ATX Power Supply Connector (20-pin ATXPWR)

This connector connects to an ATX power supply. The plug from the power
supply will only insert in one orientation because of the different hole sizes.
Find the proper orientation and push down firmly but gently making sure that
the pins are aligned.

IMPORTANT: Make sure that your ATX power supply can supply at least 10mA
on the 5-volt standby lead (+5VSB). You may experience difficulty in powering
on your system if your power supply cannot support the load. For Wake-On-
LAN support, your ATX power supply must supply at least 720mA (+5VSB).
