1.11.2.1
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.
For information about
Refer to

1.11.2.2
Fan Headers
The function/operation of the fan headers is as follows:
•
The fans are on when the board is in the S0 or S1 state
•
The fans are off when the board is off or in the S3, S4, or S5 state
•
Each fan header is wired to a fan tachometer input of the hardware monitoring and
fan control ASIC
•
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
•
4-pin fan headers are controlled by Pulse Width Modulation
