Gigabyte GA-EP45-UD3P CPU manufacturer when using an Intel Extreme Edition CPU 130W, ATX12V2X4

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, 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.

•Use of a power supply providing a 2x4 12V power connector is recommended by the

CPU manufacturer when using an Intel Extreme Edition CPU (130W).

•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 ATX_12V_2X4 power connector is compatible with power supplies with 2x2 12V power connector. When using a power supply providing a 2x4 12V and power connector, remove the protective covers from the 12V power connector and the main power connector on the motherboard. Do not insert the power supply cables into pins under the protective covers when using a power supply providing a 2x2 12V power connector.
