1/2) ATX_12V_2X4_1/ATX_12V_2X4_2/ATX (2x4 12V Power Connectors 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. 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. 5 8 1 4 ATX_12V_2X4_1/ATX_12V_2X4_2 12 24 1 13 ATX ATX_12V_2X4_1/ATX_12V_2X4_2: Pin No. Definition Pin No. 1 GND (Only for 2x4-pin 12V) 5 2 GND (Only for 2x4-pin 12V) 6 3 GND 7 4 GND 8 Definition +12V (Only for 2x4-pin 12V) +12V (Only for 2x4-pin 12V) +12V +12V ATX: Pin No. 1 2 3 4 5 6 7 8 9 10 11 12 Definition Pin No. 3.3V 13 3.3V 14 GND 15 +5V 16 GND 17 +5V 18 GND 19 Power Good 20 5VSB (stand by +5V) 21 +12V 22 +12V (Only for 2x12-pin 23 ATX) 3.3V (Only for 2x12-pin 24 ATX) Definition 3.3V -12V GND PS_ON (soft On/Off) GND GND GND NC +5V +5V +5V (Only for 2x12-pin ATX) GND (Only for 2x12-pin ATX) - 21 -
