ACPI Features

ACPI stands for Advanced Confi guration and Power Interface. The ACPI specifi ca-
tion defi nes a fl exible and abstract hardware interface that provides a standard
way to integrate power management features throughout a PC system, including
its hardware, operating system and application software. This enables the system
to automatically turn on and off peripherals such as CD-ROMs, network cards, hard
disk drives and printers.
In addition to enabling operating system-directed power management, ACPI also
provides a generic system event mechanism for Plug and Play, and an operating
system-independent interface for confi guration control. ACPI leverages the Plug and
Play BIOS data structures, while providing a processor architecture-independent
implementation that is compatible with Windows XP, Windows Vista and Windows
2008 Operating Systems.
Slow Blinking LED for Suspend-State Indicator
When the CPU goes into a suspend state, the chassis power LED will start blinking
to indicate that the CPU is in suspend mode. When the user presses any key, the
CPU will "wake up" and the LED will automatically stop blinking and remain on.

Power Supply

As with all computer products, a stable power source is necessary for proper and
reliable operation. It is even more important for processors that have high CPU
clock rates.
The X8OBN-F baseboard includes two main system power connectors (JP21/22),
four HDD power connectors (JP16~JP19), four GPU Power connectors (JPWR1~4),
and a SATA DOM power connector (JWF1). Please connect these power connectors
to the power supply to provide adequate power to the components and the system.
Also your power supply must supply 1.5A for the Ethernet ports.
Warning! To avoid damaging the power supply or the system, be sure
to connect the Main Power connectors and other power connectors as
required to the power supply. Failure to do so will void the manufacturer
warranty on your power supply and the board.
