Product information

Description

The ASUS TUF GAMING B550M-PLUS WIFI II is a micro ATX motherboard for AMD Socket AM4 processors, designed to support Ryzen 3000 and 5000 series CPUs and up to 128 GB of DDR4 memory. Built with military-grade components, upgraded DrMOS power stages and enhanced cooling features such as 2-ounce copper layers, this board provides a stable platform for gaming and high-core-count builds. Integrated WiFi 6 and 2.5 Gigabit Ethernet deliver fast networking, while onboard M.2, PCIe and SATA interfaces support modern storage configurations. Armoury Crate and BIOS FlashBack™ simplify system setup and tuning.

Advantages

The motherboard combines robust power delivery (8+2 DrMOS stages and Digi+ VRM), reinforced connectors (ProCool 8‑pin) and durable TUF components (TUF chokes and capacitors) to ensure reliable operation and extended component lifespan. Comprehensive protection features include SafeSlot PCIe, ESD guards, DRAM overvoltage protection and a corrosion-resistant stainless-steel rear I/O panel. Networking and audio features such as WiFi 6, 2.5G Ethernet and DTS® Custom for gaming headsets provide improved online performance and positional sound. Software utilities like Armoury Crate and MyASUS centralize control for RGB, fan profiles and system updates.

Suitable for

  • Gaming PCs with AMD Ryzen 3000/5000 series processors
  • Compact micro ATX builds requiring stable power and cooling
  • Users needing fast networking (WiFi 6 and 2.5G LAN)
  • Systems using multiple SSDs including M.2 and SATA with RAID 0/1/10

Key specifications

  • Form factor: Micro ATX
  • Chipset: AMD B550
  • CPU socket: Socket AM4 (supports Ryzen 3000 and 5000 series)
  • Memory: 4 × DDR4 slots, up to 128 GB
  • PCIe: 1 × PCIe x16 (Gen3), 1 × PCIe x1 (Gen3)
  • Storage interfaces: M.2, SATA III; RAID 0, 1, 10 support
  • Networking: WiFi 6 (802.11ax) and onboard 2.5 Gbps Ethernet
  • Audio: DTS® Custom for gaming headsets
  • Rear I/O: stainless-steel panel with USB Type-A and Type-C connectors

How to use

Install the motherboard into a compatible micro ATX case and connect an AM4-compatible CPU, memory modules (up to 128 GB DDR4), power supply cables including the ProCool 8‑pin connector, and storage devices (M.2 and SATA). Use the BIOS FlashBack™ feature to update UEFI if needed by copying the BIOS file to a FAT32 USB stick and pressing the BIOS FlashBack™ button. Configure system settings and RGB lighting with Armoury Crate, and enable WiFi SmartConnect or MyASUS features as required.

Usage recommendations

For stable performance, use a quality PSU that matches the board’s power requirements and ensure adequate case airflow. Pair the motherboard with compatible TUF Alliance components to simplify building and maintain consistent cooling and aesthetics. Regularly update firmware via BIOS FlashBack™ or Armoury Crate and enable DRAM overvoltage protection and ESD safeguards when connecting peripherals.
