2. Align the graphics card with the slot and press firmly until it clicks into place.
3. Secure the card to the chassis with a screw.

2.7 Power Supply Connections

• Connect the 24-pin ATX power connector.
• Connect the 8-pin (or 4+4 pin) CPU power connector.
• Connect SATA power cables to storage drives as needed.

2.8 Front Panel Connections

Connect the power button, reset button, HDD LED, power LED, and USB/audio headers from your chassis to the corresponding pins on the motherboard. Refer to the motherboard's user guide for exact pin layouts.

2.9 BIOS Update (for Ryzen 5000 series CPUs)

If installing a Ryzen 5000 series CPU, ensure your BIOS is up to date. This motherboard supports BIOS Flashback, allowing you to update the BIOS without a CPU installed.

1. Download the latest BIOS file from the ASUS support website for your specific motherboard model.
2. Rename the downloaded BIOS file according to ASUS instructions (usually to "TUF GAMING B550-PLUS.CAP").
3. Copy the renamed file to the root directory of a FAT16/FAT32 formatted USB flash drive.
4. With the system powered off but connected to power, insert the USB drive into the designated BIOS Flashback USB port on the rear I/O panel (refer to Figure 2.5).
5. Press and hold the BIOS Flashback button for approximately three seconds until the LED starts flashing.
6. Wait for the LED to stop flashing, indicating the update is complete. This may take several minutes.
7. Remove the USB drive and power on the system.

3. Operating the Motherboard

Once assembled, you can configure your system through the UEFI BIOS and install the operating system.

3.1 UEFI BIOS Overview

The UEFI BIOS (Unified Extensible Firmware Interface Basic Input/Output System) allows you to configure hardware settings, boot order, and system performance. To enter BIOS setup, press the DEL key or F2 key during system startup.

• EZ Mode: Provides a quick overview of system information, fan profiles, and boot priority.
• Advanced Mode: Offers detailed configuration options for CPU, memory, storage, and peripherals.

3.2 Fan Xpert 4 and Q-Fan Control

The motherboard features comprehensive fan control through Fan Xpert 4 software or the UEFI Q-Fan Control utility. This allows for precise tuning of fan speeds based on temperature sensors, ensuring optimal cooling and noise levels.

3.3 Aura Sync RGB Lighting

Customize the RGB lighting effects on your motherboard and connected Aura Sync compatible devices using the ASUS Aura Sync software. The motherboard includes both 4-pin RGB headers and a 3-pin addressable Gen 2 RGB header for extensive customization.

• Driver Updates: Keep all device drivers (chipset, LAN, audio, etc.) updated to ensure optimal performance and compatibility with your operating system.
• Cable Management: Ensure internal cables are neatly routed to improve airflow and prevent interference.

5. Troubleshooting

This section addresses common issues you might encounter.

5.1 No Power / No POST (Power-On Self-Test)

• Check Power Connections: Ensure the 24-pin ATX and 8-pin CPU power connectors are securely seated.
• Verify Components: Reseat the CPU, RAM modules, and graphics card. Try booting with only essential components (CPU, one RAM stick, graphics card if no integrated graphics).
• Clear CMOS: Power off the system, unplug the power cord, and remove the CMOS battery for 5-10 minutes, or use the Clear CMOS jumper if available.
• BIOS Flashback: If using a new CPU generation (e.g., Ryzen 5000 series), ensure the BIOS is updated using the BIOS Flashback feature as described in Section 2.9.

5.2 System Instability / Crashes

• Memory Issues: Run a memory diagnostic tool (e.g., Windows Memory Diagnostic, MemTest86). Try different RAM slots or modules.
• Overheating: Monitor CPU and GPU temperatures. Ensure all fans are functioning correctly and heatsinks are properly seated.
• Driver Conflicts: Update all drivers to their latest versions. Perform a clean installation of graphics drivers.
• Power Supply: Ensure your power supply unit (PSU) has sufficient wattage for all components.

5.3 Network Connectivity Issues (2.5Gb LAN)

• Driver Installation: Ensure the Realtek 2.5Gb LAN driver is correctly installed.
