Power Connector
ATX12V-compliant power supplies can turn off the system power through system
control. When an ACPI-enabled system receives the correct command, the power
supply removes all non-standby voltages.
When resuming from an AC power failure, the computer returns to the power state it
was in before power was interrupted (on or off). The computer’s response can be set
using the Last Power State feature in the BIOS Setup program’s Boot menu.

Fan Headers
The function/operation of the fan headers is as follows:
•
The fans are on when the board is in the S0 state.
•
The fans are off when the board is off or in the S3, S4, or S5 state.
•
The processor fan header is wired to a fan tachometer input and the Front and
Rear fan headers share the tachometer input of the hardware monitoring and fan
control device. All fan headers support closed-loop fan control that can adjust the
fan speed or switch the fan on or off as needed.
•
All fan headers have a +12 V DC connection.
