Carefully look at the EPIA-M main board. See the green ‘snap-in’ module? This is the PW-70

The ATX Power Supply Standard

The ATX power standard provides manufactures with a way to use the same power supplies

across many main board designs. All mother board manufacturers and power supply companies

agreed on this particular standard. The latest addition to the ATX power standard was made in

early 2002 (ATX power standard version 1.2). A special 12 V power connector (see +12 V power

connector) was introduced so that it can deliver more power for P4 (ATX12 V). A dc-dc power

supply design must follow the ATX power standards.
