[colug-432] Connect what now?

[Steve VanSlyck]

The instructions in my Gigabit motherboard manual say,

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 components of the motherboard. Before  
connecting the power connector, first make sure the power supply is  
turned on and all devices are properly installed. The power connector  
possesses a foolproof design [obviously they didn't design it for  
me!]. 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 a  
12V power connector is not connected, the computer will not start."

WTF does THAT mean? Am I supposed to connect both the 2x4 and the 2x12  
power connectors or not? And if not, then which one?
