Safety information

Electrical safety

• To prevent electrical shock hazard, disconnect the power cable from the electrical outlet

before relocating the system.

• When adding or removing devices to or from the system, ensure that the power cables

for the devices are unplugged before the signal cables are connected. If possible,

disconnect all power cables from the existing system before you add a device.

• Before connecting or removing signal cables from the motherboard, ensure that all power

cables are unplugged.

• Seek professional assistance before using an adapter or extension cord. These devices

could interrupt the grounding circuit.

• Ensure that your power supply is set to the correct voltage in your area. If you are not

sure about the voltage of the electrical outlet you are using, contact your local power

company.

• If the power supply is broken, do not try to x it by yourself. Contact a qualied service

technician or your retailer.

Operation safety

• Before installing the motherboard and adding components, carefully read all the manuals

that came with the package.

• Before using the product, ensure all cables are correctly connected and the power cables

are not damaged. If you detect any damage, contact your dealer immediately.

• To avoid short circuits, keep paper clips, screws, and staples away from connectors,

slots, sockets and circuitry.

• Avoid dust, humidity, and temperature extremes. Do not place the product in any area

where it may be exposed to moisture.

• Place the product on a stable surface.

• If you encounter technical problems with the product, contact a qualied service

technician or your retailer.

• Your motherboard should only be used in environments with ambient temperatures

between 0°C and 40°C.

Product Introduction

1.1 Before you proceed

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

any motherboard settings.

• Unplug the power cord from the wall socket before touching any component.

• Before handling components, use a grounded wrist strap or touch a safely grounded

object or a metal object, such as the power supply case, to avoid damaging them due

to static electricity.

• Before you install or remove any component, ensure that the ATX power supply is

switched off or the power cord is detached from the power supply. Failure to do so

may cause severe damage to the motherboard, peripherals, or components.

Unplug the power cord before installing or removing the motherboard. Failure to do so can

cause you physical injury and damage motherboard components.

1.2 Motherboard overview

Place this side

towards the rear

of the chassis

1-2 Chapter 1: Product Introduction

1.2.1 Layout contents

1. CPU socket

The motherboard comes with an AMD Socket AM4 designed for AMD Ryzen™ 5000 Series/

4000 G-Series/ 3000 Series Desktop Processors.

For more details, refer to 1.3 Central Processing Unit (CPU).

2. DDR4 DIMM slots

The motherboard comes with Dual Inline Memory Modules (DIMM) slots designed for DDR4

(Double Data Rate 4) memory modules.

For more details, refer to 1.4 System memory.

3. Expansion slots

This motherboard supports one PCIe 3.0 x16 graphics card and two PCIe 3.0 x1 network

cards, SCSI cards and other cards that comply with the PCI Express specication.

The PCI slot supports a card such as a LAN card, SCSI card, USB card, or any other card

that complies with PCI specications.

4. Fan headers

The Fan headers allow you to connect fans to cool the system.

5. Power connectors

These Power connectors allow you to connect your motherboard to a power supply. The

power supply plugs are designed to t in only one orientation. Find the proper orientation and

push down rmly until the power supply plugs are fully inserted.

Ensure to connect the 8-pin power plug.

• For a fully congured system, we recommend that you use a power supply unit

(PSU) that complies with ATX 12V Specication 2.0 (or later version) and provides a

minimum power of 350W.

• We recommend that you use a PSU with a higher power output when conguring a

system with more power-consuming devices. The system may become unstable or

may not boot up if the power is inadequate.

• If you are uncertain about the minimum power supply requirement for your system, we

recommend you to refer to online resources for Power Supply Wattage Calculator.
