Chapter 1: Introduction
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 X13SRA-TF motherboard accommodates a 24-pin ATX power connector. Although most
power supplies generally meet the specications required by the CPU, some are inadequate.
Additional 12V 8-pin power connections will be required to ensure adequate power supply
to the system.
Warning! To avoid damaging the power supply on the motherboard, use a power supply
that contains 24-pin and 8-pin power connectors. Be sure to connect the power sup-
plies to the 24-pin power connector (JPW1) and 8-pin power connectors (JPW2 and
JPW3) on the motherboard. Failure in doing so may void the manufacturer warranty
on your power supply and motherboard.
It is strongly recommended that you use a high quality power supply that meets ATX power
supply Specication 2.02 or above. It must also be SSI compliant.
1.7 Serial Port
The X13SRA-TF motherboard supports one serial communication connection. COM1 port
can be used for input/output. The UART provides legacy speeds 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 high-speed serial communication devices.
