The ATX 6 pin power supply connector is a seldom used motherboard power connector used to provide +12 VDC to the processor voltage regulator.

The more common connector used for this purpose is the ATX 4 pin Power Connector.

Below is the pinout for the standard ATX 6 pin (3x2) 12V power connector as of Version 2.2 of the ATX Specification (PDF).

Note: If you're using this pinout table to test power supply voltages, be aware that the voltages must be within ATX specified tolerances.

You can see other ATX power supply connector pinouts in my ATX Power Supply Pinout Tables list.
