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 SUPER X5DE8-GG/X5DEI-GG/X5DEE-M accommodates ATX power sup-
plies.
Although most power supplies generally meet the specifications re-
quired by the CPU, some are inadequate.
supply at least 400W of power and includes the additional +12V, 8-pin
power connector - an even higher wattage power supply is recommended
for high-load configurations. Also your power supply must supply 1.5A for
the LAN port(s).
NOTE: Auxiliary 12v power (J15) is necessary to support Intel Xeon
CPUs.
Failure to provide this extra power will result in the CPUs
becoming unstable after only a few minutes of operation.
Section 2-5 for details on connecting the power supply cables.
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 (info at http://www.ssiforum.org/).
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.

Super I/O

The disk drive adapter functions of the Super I/O chip include a floppy disk
drive controller that is compatible with industry standard 82077/765, a data
separator, write pre-compensation circuitry, decode logic, data rate selec-
tion, a clock generator, drive interface control logic and interrupt and DMA
logic.
The wide range of functions integrated onto the Super I/O greatly
reduces the number of components required for interfacing with floppy disk
drives. The Super I/O supports 360 K, 720 K, 1.2 M, 1.44 M or 2.88 M disk
drives and data transfer rates of 250 Kb/s, 500 Kb/s or 1 Mb/s.It also
provides two high-speed, 16550 compatible serial communication ports
You should use one that will
