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.
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 1A (12 W) fan power.

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. This PSU type has 24-pin and 4-pin power plugs.
DO NOT forget to connect the 8-pin EATX +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 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.
