What is that 6-pin Aux plug for on a PSU anyways? I have been dealing with computers since I was 10 (almost 30 now) and I have never used that connector.
 
In older boards the main voltages used were 3.3 Volts and 5 Volts. If you had a system that required more then [email protected] V or 24A@5 Volts. This would exceed the ratings of the ATX connector of the board. since the above loads are the max the connector can handle. If this happened the motherboard came with a connector for this plug to supply extra 3.3 and 5 VDC to the board. You generally only seen this plug used on older multi-processor boards.

Since todays boards use more 12VDC then anything else they added the ATX12V connector. However that 6 pin connector still comes with every PSU since it is still part of the specs that are required in order for a PSU to be a true ATX PSU.
 
If there are still any computers that old that are still running....I would love to see pictures of that! So besides the ancient boat anchors....the 6-pin serves no purpose in the computers of today.....cool it is going to be removed then!
