4. CPU fan connector (4-pin CPU_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. 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!
Only the CPU_FAN
connector support the ASUS
Advanced Q-Fan feature.

• For a fully configured system, we recommend that you use a power supply unit (PSU)
that complies with EATX 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 recommended that you use a PSU with a 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.
