1. Attach the CPU and heatsink using silica gel to ensure full contact.

2. It is suggested to select high-quality, certified fans in order to avoid
damage to the motherboard and CPU due to high temperature.

3. Never turn on the machine if the CPU fan is not properly installed.

4. Ensure that the DC power supply is turned off before inserting or
removing expansion cards or other peripherals, especially when
you insert or remove a memory module. Failure to switch off the DC
power supply may result in serious damage to your system or
memory module.

Warning:

We cannot guarantee that your system will operate normally while
over-clocked. Normal operation depends on the over-clock capacity of
your device.

Chapter 2 Installation Instructions

K8S755A Series User Manual

Take note of the following precautions before you install components
or change settings.

1. Use a grounded wrist strap or touch a safely grounded object,

such as an attached power supply, before handling components
to avoid damaging them due to static electricity.

2. Unplug the power cord before opening your chassis or touching

any components.

3. Hold components by their edges to avoid touching any exposed

integrated circuits (ICs).

4. Whenever you uninstall a component, place it on a grounded

anti-static pad or into the anti-static bag that it came in.

2.If required, apply a light coating of
silica gel to the top of the CPU.

NOTE: The CPU heatsink may have
a pre-applied thermal compound. In
that case, the silica gel is not required.

4. Connect the fan’s power cable
to the appropriate 3-pin terminal

on the motherboard.

1.Locate the CPU retention mechanism
base (surrounds the CPU socket).

3. Attach the fan to the base.

Installation of CPU Fan

New technology allows processors to run at higher and higher frequencies.
To avoid problems arising from high-speed operation, for example,
overheating, you need to install the proper fan. The following procedure is
provided for reference only, please refer to your CPU fan user guide for the
actual procedure.

Warning:

Excessive temperature will severely damage the CPU and
system. Therefore, make sure that the cooling fan works nor­mally at all times in order to prevent overheating and damaging
to the CPU.

Power Supply

This motherboard uses an ATX power supply. In order to avoid damaging any
devices, make sure that they have been installed properly prior to connecting
the power supply.

ATX 12V Power Connector: PWR2

The 4 pin ATX 12V power supply connects to PWR2 and provides power to the
CPU.

ATX Power Connector: PWR1

PWR1 is the ATX power supply connector. Make sure that the power supply
cable and pins are properly aligned with the connector on the motherboard.
Firmly plug the power supply cable into the connector and make sure it is secure.

You have to press the power button for more than four seconds if
you change the default Instant-off setting to “Delay 4 Sec” for the
“Soft-Off by Power Button” option in the BIOS Power Management
Setup.

HDD connectors: PIDE & SIDE

These connectors support the provided UltraDMA133/100/66 IDE hard disk rib­bon cable. Connect the cable’s blue connector to the primary (recommended)
or secondary IDE connector, then connect the gray connector to the Ultra DMA133/
100/66 slave device (hard disk drive) and the black connector to the Ultra DMA133/
100/66 master device. If you install two hard disks, you must configure the
second drive as a slave device by setting its jumper accordingly. Refer to the

hard disk documentation for the jumper settings.

Attention:

Ribbon cables are directional, therefore, make sure to always con­nect with the cable on the same side as pin 1 of the PIDE/SIDE or
FLOPPY connector on the motherboard.
