Motherboard Information
4.
CPU, Chassis, and Power Fan Connectors
(3-pin CPU_FAN, PWR_FAN, CHA_FAN)
The fan connectors support cooling fans of 350mA~740mA (8.88W max.) or a
total of 1A~2.22A (26.64W max.) at +12V. Connect the fan cables to the fan
connectors on the motherboard, making sure that the black wire of each cable
matches the ground pin of the connector.
Do not forget to connect the fan cables to the fan connectors. Lack of sufficient
air flow within the system may damage the motherboard components. These
are not jumpers! DO NOT place jumper caps on the fan connectors!

ATX power connectors (20-pin ATXPWR1)
These connectors connect to an ATX 12V power supply. The plugs from the

the proper orientation and push down firmly until the connectors completely fit.
Make sure that your ATX 12V power supply can provide 8A on the +12V lead
