ASUS ROG STRIX B650-A GAMING WIFI Motherboard Quick Start Guide

Motherboard Layout

The diagram illustrates the physical layout of the ASUS ROG STRIX B650-A GAMING WIFI motherboard, highlighting key components and connectors. It shows the AMD AM5 CPU socket, four DDR5 DIMM memory slots (DIMM_A1, DIMM_A2, DIMM_B1, DIMM_B2), three M.2 slots for storage devices, multiple PCIe slots for expansion cards (including PCIEX16_1, PCIEX16_2, and PCIEX1_ slots), various power connectors (24-pin ATX_PWR, 8-pin ATX_12V), fan headers (CPU_FAN, AIO_PUMP, CHA_FAN), USB headers, SATA ports, front panel connectors, audio connectors, and the BIOS Flashback button. The motherboard dimensions are approximately 24.4cm (9.6 inches) wide and 30.5cm (12 inches) tall.

Step 1: Install the CPU

Install the CPU

This step guides the installation of the Central Processing Unit (CPU) into the motherboard's socket.

• Open the CPU socket lever by pushing it down and away from the socket.
• Align the CPU's triangle mark with the corresponding triangle mark on the socket.
• Gently place the CPU into the socket, ensuring it sits flush without force.
• Close the CPU socket lever by pushing it down and back into its original position.

The motherboard features an AMD AM5 socket for the CPU.

Step 2: Install the CPU Fan

Install the CPU fan

This step describes how to install the CPU cooler and fan.

• Mount the CPU cooler's retention module or bracket onto the motherboard.
• Attach the CPU fan to the heatsink.
• Connect the CPU fan cable to the CPU_FAN header on the motherboard.

The guide shows different mounting methods, referred to as "Type 1" and "Type 2", for various cooler designs.

Step 3: Install Memory Modules

Install memory modules

This step covers the installation of RAM modules (memory modules).

• Open the clips on the DIMM slots (e.g., DIMM_A1, DIMM_A2, DIMM_B1, DIMM_B2).
• Align the notch on the memory module with the notch in the DIMM slot.
• Insert the memory module vertically into the slot and press down firmly on both ends until the clips on the sides snap into place, securing the module.

The motherboard supports DDR5 DIMM modules.

Step 4: Install Storage Devices

Install storage devices

This step explains how to install storage devices, including M.2 SSDs.

• Install M.2 SSDs into the designated M.2 slots (M.2_1, M.2_2, M.2_3).
• Note for M.2 Installation: Remove the screws and the retention module only. Do not remove the plate on the bottom.
• Install other storage devices, such as SATA HDDs or SSDs, into their respective bays or connect them to SATA ports.

Step 5: Install Expansion Card(s)

Install expansion card(s)

This step guides the installation of expansion cards, such as graphics cards or network cards.

• Open the retention clip on the appropriate PCIe slot.
• Align the expansion card's connector with the PCIe slot.
• Insert the card firmly into the slot until it is fully seated.
• Secure the expansion card to the computer case using the screw mechanism.

Step 6: Install the System Panel Connector

Install the system panel connector

This step describes connecting the front panel connectors from the computer case to the motherboard.

• Connect the various small cables from the computer case's front panel (e.g., power button, reset button, HDD LED, power LED, front USB ports, front audio jacks) to the corresponding pins on the motherboard's front panel header.
• Consult the motherboard manual for the exact pin layout.

Step 7: Install ATX Power Connectors

Install ATX power connectors

This step details connecting the main power supply unit (PSU) cables to the motherboard.

• Connect the 24-pin ATX power connector (ATX_PWR) from the PSU to the motherboard.
• Connect the 4+4 or 8-pin EPS/ATX12V CPU power connector (ATX_12V_1, ATX_12V_2) from the PSU to the motherboard.

Step 8: Connect Input/Output Devices

Connect input/output devices

This step covers connecting external peripherals and display devices.

• Connect input devices (keyboard, mouse) via USB ports.
• Connect output devices like monitors via HDMI or DisplayPort.
• Connect network cables (LAN) and any other peripherals to the rear I/O panel.

The diagram shows connections to the rear I/O panel and mentions "Supports BIOS FlashBack™".

Step 9: Power on the System and Install Operating System and Drivers

Power on the system and install operating system and drivers

This is the final step in the quick start guide.

• Connect the power cord, turn on the system using the case's power button.
• Proceed to install the operating system (e.g., Windows, Linux) and necessary hardware drivers (e.g., chipset, graphics, audio, network drivers) from the provided media or manufacturer's website.
