ASUS EZ Plug™
This patented ASUS technology lets you use your existing power supply
rather than buying a new ATX 12V power supply. The ASUS EZ Plug™ is
a 4-pin auxillary +12V connector mounted on the motherboard that
connects a regular 4-pin device power connector from the power supply.
This connector is necessary to provide the additional power required by
the P4 CPU. Refer to page 2-29.

On audio models, a digital audio connector is onboard to accommodate
the Sony/Philips Digital Interface (S/PDIF) In/Out module, which supports
coaxial interfaces. Experience 5.1-channel surround sound and enhanced
3D audio while playing DVDs and computer games. See page 2-33.
