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 Windows 7, Windows 8, and Windows 2008

Power Supply

As with all computer products, a stable power source is necessary for proper and
reliable operation. It is strongly recommended that you use a high quality power
supply that meets ATX power supply Specification 2.02 or above. It must also be
SSI compliant. (For more information, please refer to the web site at http://www.
ssiforum.org/). Additionally, in areas where noisy power transmission is present,
you may choose to install a line filter to shield the computer from noise. It is rec-
ommended that you also install a power surge protector to help avoid problems
caused by power surges.
