You can attach a FireWire/1394 cable to this connector if your chassis suppots the front panel IEEE1394 port. Connect the 1394 cable to ASUS Q-Connector (1394, red) first, and then install the Q-Connector (1394) to the 1394 connector onboard. 6. CPU, chassis and power fan connectors (4-pin CPU_FAN, 3-pin CHA_FAN1-4, 3-pin PWR_FAN) The fan connectors support cooling fans of 350 mA ~ 2000 mA (24 W max.) or a total of 1 A ~ 7 A (84 W max.) at +12V.
