- 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 the main power connector is compatible with power supplies with 2x10 power connectors when using a 2x12 power supply remove the protective cover from the main power connector on the motherboard do not insert the power supply cable into pins under the protective cover when using a 2x10 power supply 21
- 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 first 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 21
