This one has a pair of six-pin leads labeled P1 and P2 going to the motherboard and another pair (with only orange and black wires) labeled P10 and P11 powering expansion slots on a riser card. There are also five standard 4-pin Molex power leads, one small 4-pin floppy drive power lead and a small three-wire connector which goes toward the power switch in the front of the case.
