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 of 1 GHz and faster.
The P8SAA+ accommodates 12V ATX power supplies. Although
most power supplies generally meet the specifications required by the CPU,
some are inadequate. A 2 amps of current supply on a 5V Standby rail is
strongly recommended.
The P8SAA+ accommodates ATX power supplies. It is strongly recom-
mended that you use a high quality power supply that meets ATX power
supply Specification 2.02 or above. You should use one that will supply at
least 350W of powerAlso your power supply must supply 1.5A for the
Ethernet ports. It must also be SSI compliant (info at http://
www.ssiforum.org/). Additionally, in areas where noisy power transmis-
sion is present, you may choose to install a line filter to shield the computer
from noise. It is recommended that you also install a power surge protector
to help avoid problems caused by power surges. (*Note: an additional
12V 4-pin power (J41) connection is required for high-load system
configurations.)
Wake-On-LAN (WOL)
Wake-On-LAN is defined as the ability of a management application to re-
motely power up a computer that is powered off. Remote PC setup, up-
dates and asset tracking can occur after hours and on weekends so that
daily LAN traffic is kept to a minimum and users are not interrupted. The
motherboard has a 3-pin header (WOL) to connect to the 3-pin header on a
Network Interface Card (NIC) that has WOL capability. Wake-On-LAN must
be enabled in BIOS. Note that Wake-On-LAN can only be used with an ATX
2.01 (or above) compliant power supply.
