Power-On/Off (Remote)
This board has a 20-pin ATX power supply connector (Figure 4). For power
supplies that support the
Remote On/Off feature, this should be connected to the
mainboard front panel PW_ON connector for the computer power On/Off button.
This board has been designed with “Soft Off" function. You can turn off the system
in two ways: by pressing the front panel power On/Off button or using the "Soft
Off" function that can be controlled by an operating system such as Windows
®
XP/
ME/2000/98.
Note: For maintaining the DDR SDRAM power during STR (ACPI S3) function, it is
strongly recommended to use power supplies that have a +5VSB current of (>
=) 2A. Please check the 5VSB’s specification printed on the power supply’s
outer case.
Note: The board requires a minimum of 250 Watt power supply to operate. Your
system configuration (amount of memory, add-in cards, peripherals, etc.) may
exceed this minimum power requirement. To ensure that adequate power is
provided, use a 300 Watt (or higher) power supply.
I/O Shield Connector
The board is equipped with an I/O back panel (Figure 3). Ensure that your computer
case has the appropriate I/O cutout.
