•  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 350 W.

•  DO NOT forget to connect the 4-pin ATX +12V power plug. Otherwise, the system will 

not boot up.

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

system with more power-consuming 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.

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.

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, 4-pin CHA_FAN)
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.

The CPU_FAN connector supports a CPU fan of maximum 2A (24 W) fan power.
