PW1/PW2 – ATX Power Supply On/Off Switch Connectors
Due to most of the ATX power supplies without On/Off switch, attach
this 2-pin switch from the PC case for turning on or off of your power
supply. There are two different types of the On/Off switch connectors of
this motherboard: latch type (PW1) and momentary type (PW2). Latch
type is the triditional AT type of On/Off switch and momentary type is a
non-latch (one-touch) type of On/Off switch. You need to choose one or
the other type of these two switches depending on the PC case that you
have. Notice that you have to unplug the ATX power supply connector
before installing any add-on plug/unplug card when you use the
momentary type of the On/Off switch.
CN4, CN5 – COM1/COM2 Connectors
Attach COM1/COM2 device cable to these connectors.
