Chapter 1: 1 Product Introduction Product Introduction 1.1 Before you proceed Take note of the following precautions before you install motherboard components or change any motherboard settings. 1.2 • 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.
1.2.1 Layout contents 1. CPU socket The motherboard comes with an AMD Socket AM4 for AMD Ryzen™ 5000 Series/ 5000 G-Series/ 4000 G-Series/ 3000 Series Desktop Processors*. For more details, refer to 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 System memory. 3. Expansion slots This motherboard supports two PCIe x16 graphics cards and three PCIe 3.
Ensure to connect the 8-pin power plug. • For a fully configured system, we recommend that you use a power supply unit (PSU) that complies with ATX 12V Specification 2.0 (or later version) and provides a minimum power of 350 W. • We recommend that you use a PSU with a higher power output when configuring a system with more power-consuming devices. The system may become unstable or may not boot up if the power is inadequate.
The Addressable Gen 2 headers support WS2812B addressable RGB LED strips (5V/Data/ Ground), with a maximum power rating of 3A (5V), and the addressable headers on this board can handle a combined maximum of 500 LEDs. Before you install or remove any component, ensure that the 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. • Actual lighting and color will vary with LED strip.
13. COM Port header COM RXD DTR DSR CTS This header is for a serial (COM) port. Connect the serial port module cable to this header, then install the module to a slot opening at the back of the system chassis. DCD TXD GND RTS RI PIN 1 If you want to connect a high-definition front panel audio module to this header, set the Front Panel Type item in the BIOS setup to [HD Audio]. By default, this header is set to [HD Audio]. HD-audio-compliant pin definition The SPI_TPM module is purchased separately.
This header is for the system power button. Pressing the power button turns the system on or puts the system in sleep or soft-off mode depending on the operating system settings. Pressing the power switch for more than four seconds while the system is ON turns the system OFF. • Reset button (2-pin RESET) This 2-pin header is for the chassis-mounted reset button for system reboot without turning off the system power. 17.
