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.
The X11SPW-CTF/-TF motherboard accommodates a 24-pin ATX power supply. Although
most power supplies generally meet the specications required by the CPU, some are
inadequate. In addition, one 12V 8-pin power connection is also required to ensure adequate
power supply to the system.
Warning: To avoid damaging the power supply or the motherboard, be sure to use a
power supply that contains a 24-pin and an 8-pin power connector. Be sure to connect
the power supplies to the 24-pin power connector (JPWR2), and the 8-pin power con-
nector (JPWR1) 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 Specication 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 lter 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.
1.7 Serial Port
The X11SPW-CTF/-TF motherboard supports two serial communication connections. COM
Ports 1 and 2 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.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.
