Voltage selector

The PSU has a 115 V/230 V voltage selector switch located beside the power

connector. Use this switch to select the appropriate system input voltage according to the voltage supply in your area.

If the voltage supply in your area is 100-127 V, set this switch to 115 V.

If the voltage supply in your area is 200-240 V, set this switch to 230 V.

Take note of the following precautions before you install components into the system.

•

Use a grounded wrist strap or touch a safely grounded object or a metal object, such as the power supply case, before handling components to avoid damaging them due to static electricity.

•

Hold components by the edges to avoid touching the ICs on them.

•

Whenever you uninstall any component, place it on a grounded antistatic pad or in the bag that came with the component.

The motherboard comes with a standby power LED that lights up to indicate that the system is ON, in sleep mode, or in soft-off mode. This is a reminder that you should shut down the system and unplug the power cable before removing or plugging in any motherboard component. The illustration below shows the location of the onboard LED.

2.3 Removing the side cover and front panel assembly

Follow the steps below to remove the side cover and front panel assembly.

1. Remove the cover screws on the rear panel.

2. Pull the side cover toward the rear panel until its hooks disengage from the

chassis tab holes. Set the side cover aside.

3. Locate the front panel assembly hooks, then lift them until they disengage

from the chassis.

4. Swing the front panel assembly to the right, until the hinge-like tabs on the right side of the assembly are exposed.

5. Remove the front panel assembly, then set it aside.

2.4.1 Overview

• Make sure that all power cables are unplugged before installing the CPU.

• Connect the chassis fan cable to the CHA_FAN connector to ensure system stability.

The AM2+/AM2 socket has a different pinout from the 940-pin socket designed

for the AMD Opteron processor. Ensure you use a CPU designed for the

AM2+/AM2 socket. The CPU ts in only one correct orientation. DO NOT force

the CPU into the socket to prevent bending the connectors on the socket and

damaging the CPU!

2.4.2 Installing CPU

To install a CPU:

1. Locate the CPU socket on the motherboard.

2-5ASUS V4-M3A3200

2. Unlock the socket by pressing the

lever sideways, then lift it up to a

90º angle.

Socket lever

Make sure that the socket lever is lifted up to a 90º angle; otherwise, the CPU will not t in completely.

3. Position the CPU above the socket

such that the CPU corner with the gold triangle matches the socket corner with a small triangle.

4. Carefully insert the CPU into the

socket until it ts in place.

Please make sure your CPU is fully plugged-in to reduce abnormal symptom.

5. When the CPU is in place, push down the socket lever to secure the CPU. The lever clicks on the side tab to indicate that it is locked.

6. Install a CPU heatsink and fan following the instructions that came with the heatsink package.

2.4.3 Installing the CPU fan and heatsink assembly

The AMD Phenom™ FX / Phenom / Athlon™ 64 / Sempron™ / Athlon 64X2 /

Athlon 64 FX processor requires a specially designed heatsink and fan assembly to ensure optimum thermal condition and performance..

Ensure that you use only qualied heatsink and fan assembly.

Follow these steps to install the CPU heatsink and fan.

1. Place the heatsink on top of the installed CPU, making sure that the heatsink

ts properly on the retention module base.

• The retention module base is already installed on the motherboard upon purchase.

• You do not have to remove the retention module base when installing the CPU or installing other motherboard components.

• If you purchased a separate CPU heatsink and fan assembly, make

sure that a Thermal Interface Material is properly applied to the CPU heatsink or CPU before you install the heatsink and fan assembly.

Your boxed CPU heatsink and fan assembly should come with installation instructions for the CPU, heatsink, and the retention mechanism. If the instructions in this section do not match the CPU documentation, follow the latter.

2. Attach one end of the retention bracket to the retention module base.

2-8 Chapter 2: Basic installation

3. Align the other end of the retention bracket (near the retention bracket lock)

to the retention module base. A clicking sound denotes that the retention bracket is in place.

Make sure that the fan and heatsink assembly perfectly ts the retention

mechanism module base, otherwise you cannot snap the retention bracket in place.

4. Push down the retention bracket lock on the retention mechanism to secure the heatsink and fan to the module base.

5. When the fan and heatsink assembly is in place, connect the CPU fan cable to the connector on the motherboard labeled CPU_FAN.

Do not forget to connect the CPU fan connector! Hardware monitoring errors

can occur if you fail to plug this connector.
