Power-On/Off (Remote)
This board has a 20-pin ATX and a 4-pin ATX12V 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.
The 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 (incorporated in the mainboard's onboard circuit controller) that can
be controlled by an operating system such as Windows
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 that has been 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 the minimum power requirement but to ensure that adequate power is
provided, use a 300 Watt (or greater) power supply. Also your power supply
must support 4-pin ATX 12V connector.
