power

I am trying to build a computer, placing an ASUS P8H67-I DELUXE in a custom retro C64 case.

The case is an extra small form factor which can accomodate the Mini ITX board, but requires an external power supply, similar to the power-bricks that laptops use.

I am looking at different power supplies and like these, but cannot figure out whether/how to power this system because they provide a 24-pin connector, but the motherboard has a 4-pin connector as well.

Is the 4-pin connector optional or is it required? If it is required, how can I provide power for this system?
