ASUS TUF Gaming B550M-Plus WiFi II mATX Motherboard AMD AM4
The ASUS TUF Gaming B550M-Plus WiFi II is a micro ATX motherboard for AMD Ryzen builders who need gaming-ready features, fast storage support, and reliable power delivery in a compact form factor. It combines PCIe 4.0 connectivity, Wi-Fi 6, and comprehensive cooling in a board designed for durability under sustained load.
Why this product
PCIe 4.0 and dual M.2 storage
The first M.2 slot supports PCIe 4.0 x4 on Ryzen 5000 and 3000 series, delivering 64 Gb/s bandwidth for the fastest NVMe drives. A second M.2 slot adds storage flexibility with PCIe 3.0 x4 support.
Wi-Fi 6 and 2.5 Gb Ethernet
Wi-Fi 6 (802.11ax) with 2x2 antenna and a dedicated 2.5 Gb Ethernet port with TUF LANGuard protection ensure low-latency gaming connectivity.
10 power stages with military-grade components
8+2 DrMOS configuration, ProCool connector, and DIGI+ VRM deliver stable voltage under load. TUF-grade capacitors and shielding are rated for long-term reliability.
Comprehensive cooling with Fan Xpert 2+
VRM, M.2, and PCH heatsinks combined with hybrid fan headers and the Fan Xpert 2+ utility let you control thermal performance across multiple temperature zones.
AI Noise Cancelation for online gaming
Two-way AI noise reduction filters background noise from both input and output, improving voice clarity in games and video calls without manual tuning.

- Supports AMD Ryzen 5000, 5000G, 4000G, and 3000 series processors in the AM4 socket.
- Accepts standard DDR4 memory up to 4866 MHz (overclocked) across four DIMM slots.
- Fits micro ATX cases; rear I/O bracket is stainless steel.
- BIOS FlashBack button allows BIOS updates without a CPU or power, useful for CPU upgrades.
- Supports RAID 0, 1, and 10 across the four SATA ports and both M.2 slots.
- PCIe 4.0 x4 speed on the first M.2 slot is limited to Ryzen 5000 and 3000 series; Ryzen 5000G and 4000G users get PCIe 3.0 x4 on that slot.
Best for
- Ryzen 5000 series builders seeking a compact, gaming-focused platform with PCIe 4.0 storage.
- Builders who need Wi-Fi 6 and reliable 2.5 Gb Ethernet in a micro ATX footprint.
- Users prioritizing sustained performance under load with excellent power delivery and cooling.
- Content creators and streamers using the AI noise cancelation for clearer audio input and output.
Trade-offs
- Users building with Ryzen 5000G or 4000G series will not access PCIe 4.0 speeds on the primary M.2 slot; they are limited to PCIe 3.0 x4.
- Systems requiring more than one PCIe x16 slot for dual graphics or expansion cards; this board has only one full-speed PCIe 4.0/3.0 x16 slot.
- Builders needing more than four SATA devices; only four SATA 6 Gb/s ports are available.
- Users requiring a built-in external I/O such as a parallel port; rear I/O is limited to USB, audio, Ethernet, and DisplayPort/HDMI.
- Comprehensive cooling: VRM heatsinks, PCH fanless heatsink, M.2 heatsink, hybrid fan headers and Fan Xpert 2+ utility
- Ultrafast connectivity: PCIe 4.0 M.2, USB 3.2 Gen 2 Type-A and Type-C® support
- Made for online gaming: Wi-Fi 6, Realtek 2.5Gb Ethernet, and TUF LANGuard
- Two-Way AI Noise Cancelation: Reduces background noise from the microphone and audio output for crystal-clear communication in games or video conferences
- AMD AM4 socket: Ready for Ryzen™ 5000 Series/ 5000 G-Series/ 4000 G-Series/ 3000 Series Desktop Processors
- Enhanced power solution: 8+2 DrMOS power stages, ProCool connector, military-grade TUF components, and DIGI+ VRM for maximum durability
- Multiple temperature sources
- 4-pin PWM/DC fan
- Smart protection
