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.

hardware monitoring and fan control.
• All fan headers support closed-loop fan control that can adjust the fan speed or
switch the fan on or off as needed.
