23. Chassis, CPU , & Power Supply Fan Connectors (3-pin CHA_, CPU_, PWR_FAN)

These connectors support cooling fans of 500mAMP (6 Watts) or less. Orien-

tate the fans so that the heat sink fins allow airflow to go across the onboard heat

sink(s) instead of the expansion slots. Depending on the fan manufacturer, the

wiring and plug may be different. The red wire should be positive, while the

black should be ground. Connect the fan’s plug to the board taking into consid-

eration the polarity of the this connector. NOTE: The “Rotation” signal is to

be used only by a specially designed fan with rotation signal.

WARNING! The CPU and/or motherboard will overheat if there is no airflow

across the CPU and onboard heatsinks. Damage may occur to the motherboard

and/or the CPU fan if these pins are incorrectly used. These are not jumpers,

do not place jumper caps over these pins.

24. ATX Power Supply Connector (20-pin block ATXPWR)

This connector connects to an ATX power supply. The plug from the power sup-

ply will only insert in one orientation because of the different hole sizes. Find the

proper orientation and push down firmly 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 power-

ing 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.
