You'll need those other four pins also (making the total of 8 pins). The connector is right next to the 4-pin connector you used. Again, just pop off the little cover, and connect the additional four pins.
ACtually looking at the picture of his mobo, it does only have a 4 pin socket. Unusual for a board that supposedly supports quads. You can try finding the 4 pin ATX plug on your PSU and putting it in that socket, it should work, but it may not with the quad. If it does work, don't expect much overclocking ability that's for sure.
