1.5 ACPI Features
ACPI stands for Advanced Configuration and Power Interface. The ACPI specification defines
a flexible and abstract hardware interface that provides a standard way to integrate power
management features throughout a computer system, including its hardware, operating
system and application software. This enables the system to automatically turn on and off
peripherals such as 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 configuration control. ACPI leverages the Plug and Play BIOS data structures,
while providing a processor architecture-independent implementation that is compatible with
appropriate Windows operating systems. For detailed information regarding OS support,
please refer to the Supermicro website.
1.6 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 where
noisy power transmission is present.
The X12DPG-QR motherboard accommodates two CRPS PSUs (JPWR1/JPWR2). Although
most power supplies generally meet the specifications required by the CPU, some are
inadequate. In addition, two 12V 8-pin power connections (JGPU_PWR1/JGPU_PWR2) are
also required to ensure adequate power supply to the GPUs in the system. Four 8-pin power
connectors (RSC_PWR 1~4) are reserved for riser card use.
