I just bought a antec 550 truepower 2.0 and have a P4C800-E MB, I know it is a 20 pn on the power however I am confused about the 4pin atx 12v connector. What is that for and am I supposed to hook both the 20 pin and 4pin up and how does the dual 12v fit into the picture, can not continue assembly until I know , please help.
