You need to connect both 4-pin and 8-pin in your mobo from psu. Uncover them use in mobo.
Thanks for your suggestion mubin. I wanted to keep this message posted for a while before I awarded a badge and give other people a chance to respond, however I don't think many people are willing to pay the price for an ASUS Rampage IV Extreme mobo so many people may not have known the answer. Since you are the only one who did provide a reasonable response I think you deserve the badge to my post!
After viewing several different builds on Youtube I decided to play it safe and connect both the 4-pin and 8-pin sockets and my new build works fine. That half cover over the 8-pin socket can cause a lot of confusion. >.< I hope in the future other people can experience this kind of power this hardware can provide to games. It's like Christmas every week! Thank you to all of the people who viewed my post. Happy gaming!
