This board has a 24-pin ATX and a 4-pin ATX12V power supply connector to support
power supplies with Remote On/Off feature. The 4-pin ATX12V connector must be
plugged in for the system to operate safely. The chassis power button should be
connected to the mainboard front panel PW_ON header.
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

5VSB's specification printed on the power supply's outer case.
Note:
The board requires a minimum of 400 Watt power supply to operate. Your system configura-
tion (amount of memory, add-in cards, peripherals, etc.) may exceed this minimum power
requirement. To ensure that adequate power, use a 550 Watt (or higher) power supply and
recommend to use PSU that have 12V current total of (>=) 20A.
