ATX power connectors (24-pin EATXPWR, 4-pin ATX12V)
These connectors are for ATX power supply plugs. The power supply plugs are

designed to fit these connectors in only one orientation. Find the proper orientation 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 400 W.

• Do not forget to connect the 4-pin ATX12V power plug. Otherwise, the system will not

boot.

• We recommend that you use a PSU with a higher power output when configuring a

system with more power-consuming devices or when you intend to install additional

devices. The system may become unstable or may not boot up if the power is

inadequate.

• 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.

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!

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, ensuring that the black wire of each cable matches the ground pin of

the connector.
