Never connect a 1394 cable to the USB connectors. Doing so will
damage the motherboard!
5. USB connectors (10-1 pin USB56, USB78)
These connectors are for USB 2.0 ports. Connect the USB module
cable to any of these connectors, then install the module to a slot
opening at the back of the system chassis. These USB connectors
comply with USB 2.0 specification that supports up to 480 Mbps
connection speed.
The USB module is purchased separately.
4. CPU and Chassis Fan connectors
(4-pin CPU_FAN, 3-pin CHA_FAN)
The fan connectors support cooling fans of 350 mA~740 mA (8.88
W max.) or a total of 1 A~2.22 A (26.64 W 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.
Insufficient air flow inside the system may damage the motherboard
components. These are not jumpers! Do not place jumper caps on the
fan connectors!
