ATX power connectors (24-pin EATXPWR, 4-pin ATX12V) Correctly orient the ATX power supply plugs into these connectors and push down firmly until the connectors completely fit. • For a fully configured system, we recommend that you use a power supply unit (PSU) that complies with ATX 12 V Specification 2.0 (or later version) and provides a minimum power of 300 W. • If you are uncertain about the minimum power supply requirement for your system, refer to the Recommended Power Supply Wattage Calculator at http://support. asus.com/PowerSupplyCalculator/PSCalculator.aspx?SLanguage=en-us for details. CPU and chassis fan connectors (4-pin CPU_FAN, 4-pin CHA_FAN1/2) Connect the fan cables to the fan connectors on the motherboard, ensuring 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! The CPU_FAN connector supports a CPU fan of maximum 2A (24 W) fan power. Only the 4-pin CPU fan supports the ASUS Fan Xpert feature.
