1-7 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.
This motherboard accommodate a 24-pin ATX power supply. Although
most power supplies generally meet the specifications required by the
CPU, some are inadequate. In addition, the 12V 8-pin power connector
located at JPW2 is also required to ensure adequate power supply to the
system. Also your power supply must supply 1.5A for the Ethernet ports.
Attention! To prevent damage to the power supply or mother-
board, please use power supplies that contain 24-pin and 8-pin
power connectors. Be sure to connect these connectors to the
24-pin (JPW1) and the 8-pin (JPW2) power connectors on the
motherboard.
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 website
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 recommended that you also install a power
surge protector to help avoid problems caused by power surges.

1-8 Super I/O

The Super I/O supports one high-speed, 16550 compatible serial commu-
nication port (UART). Each UART includes a 16-byte send/receive FIFO, a
programmable baud rate generator, complete modem control capability
and a processor interrupt system. Both UARTs provide legacy speed with
a baud rate of up to 115.2 Kbps as well as an advanced speed with baud
rates of 250 K, 500 K, or 1 Mb/s, which support higher speed modems.
The Super I/O provides functions that comply with ACPI (Advanced Con-
figuration and Power Interface), which includes support of legacy and
ACPI power management through an SMI or SCI function pin. It also
features auto power management to reduce power consumption.
