1/2) ATX_12V_2X4/ATX (2x4 12V Power Connector and 2x12 Main Power Connector)
With the use of the power connector, the power supply can supply enough stable power to all the components
onthemotherboard.Beforeconnectingthepowerconnector,rstmakesurethepowersupplyisturned
off and all devices are properly installed. The power connector possesses a foolproof design. Connect the
power supply cable to the power connector in the correct orientation.
The 12V power connector mainly supplies power to the CPU. If the 12V power connector is not connected,
the computer will not start.
To meet expansion requirements, it is recommended that a power supply that can withstand high
powerconsumptionbeused(500Worgreater).Ifapowersupplyisusedthatdoesnotprovidethe
required power, the result can lead to an unstable or unbootable system.

3/4) CPU_FAN/SYS_FAN (Fan Headers)
All fan headers on this motherboard are 4-pin. Most fan headers possess a foolproof insertion design.
Whenconnectingafancable,besuretoconnectitinthecorrectorientation(theblackconnectorwireis
thegroundwire).Thespeedcontrolfunctionrequirestheuseofafanwithfanspeedcontroldesign.For
optimum heat dissipation, it is recommended that a system fan be installed inside the chassis.
• Be sure to connect fan cables to the fan headers to prevent your CPU and system from overheating.
Overheating may result in damage to the CPU or the system may hang.
• Thesefanheadersarenotcongurationjumperblocks.Donotplaceajumpercapontheheaders.
