ASUS TUF GAMING B550M-PLUS WIFI II AM4 Micro-ATX Motherboard

The ASUS TUF GAMING B550M-PLUS WIFI II is a motherboard in the micro-ATX format built for AMD’s AM4 processors from the Ryzen 3000, 4000, and 5000 families. Designed under the TUF Gaming banner, it focuses on dependable power delivery and long-term reliability, making it a solid foundation for gaming rigs, home offices, or compact content-creation workstations.

The AMD B550 chipset opens access to PCIe 4.0 for graphics cards and NVMe drives. A reinforced PCIe 4.0 x16 slot handles today’s power-hungry GPUs, while two M.2 sockets—one at PCIe 4.0 speed and one at PCIe 3.0—let you install high-performance SSDs. Four SATA III ports with RAID 0, 1, and 10 support provide additional storage flexibility. Memory needs are met by four DDR4 slots that accept as much as 128 GB and can reach 4866 MT/s when paired with compatible modules.

Networking options are ready for both wired and wireless setups. Integrated Wi-Fi 6 and Bluetooth 5.2 simplify cable-free connectivity, and a 2.5 Gb Ethernet port delivers low-latency, high-bandwidth links for competitive online play or large file transfers. Rear I/O includes USB 3.2 Gen 2 in both Type-A and Type-C formats for fast peripherals, alongside HDMI 2.1 and DisplayPort 1.2 for systems that rely on Ryzen processors with built-in graphics.

On the audio side, a Realtek 7.1-channel codec with an optical S/PDIF output supplies clean sound for headsets and speaker systems. For builders who like visual flair, two addressable RGB headers tie into ASUS Aura Sync so lighting can match the rest of the setup. Altogether, the board fits naturally into compact ATX or small tower cases where users want modern features without the footprint of a full-sized motherboard.
