Asus TUF Gaming B550 Plus Wifi DDR4 AMD Motherboard

The ASUS TUF Gaming B550-Plus WiFi is an ATX form-factor motherboard built on the AMD B550 chipset and designed for the AM4 socket, supporting AMD Ryzen 5000 Series, 5000 G-Series, 4000 G-Series, and 3000 Series desktop processors. It provides a strong foundation for gaming and content-creation builds that demand fast storage, reliable networking, and clean power delivery. Power delivery is handled by an 8+2 DrMOS power-stage design paired with ProCool connectors and ASUS Digi+ VRM digital power control. These components work together to supply stable voltage to the CPU under demanding workloads, while the aluminium VRM heatsink, PCH fanless heatsink, and dual M.2 heatsinks keep temperatures in check. Five fan headers — including a CPU fan, CPU OPT, three chassis headers, and a dedicated AIO pump connector — combine with the Fan Xpert 4 software utility to give you precise thermal management across the entire platform. Storage is handled by two M.2 Socket 3 slots supporting sizes up to 22110. When a Ryzen 5000 or 3000 Series non-G processor is installed, the primary M.2 slot runs at PCIe 4.0 x4 speeds; the second slot operates at PCIe 3.0 x4. Six SATA 6 Gb/s ports provide additional drive capacity, with RAID 0, 1, and 10 support. Note that populating the second M.2 slot disables SATA ports 5 and 6. The primary PCIe x16 slot runs at PCIe 4.0 x16 with Ryzen 5000 or 3000 non-G CPUs, or PCIe 3.0 x16 with G-Series APUs. A second PCIe 3.0 x16 slot (operating at x4 bandwidth) and three PCIe 3.0 x1 slots round out expansion options. AMD 2-Way CrossFireX is supported. Four DDR4 DIMM slots accommodate up to 128 GB of unbuffered memory in dual-channel mode. Native speeds range from DDR4-2133 up to DDR4-3200, with overclocking profiles extending to DDR4-4866 (O.C.). Networking is a standout feature: the board integrates an Intel Wi-Fi 6 AX200 module (802.11 a/b/g/n/ac/ax, 2x2, up to 2.4 Gbps max data rate, dual-band 2.4 GHz / 5 GHz, OFDMA, MU-MIMO) alongside a Realtek RTL8125B 2.5 Gb wired Ethernet controller and TUF LANGuard surge protection. The rear panel carries eight USB ports: two USB 3.2 Gen 2 (one Type-A, one Type-C), four USB 3.2 Gen 1 Type-A, and two USB 2.0 Type-A. A BIOS FlashBack button allows firmware updates without a CPU or RAM installed. Display outputs include DisplayPort 1.2 and HDMI 2.1 (4K @ 60 Hz), active only when using an APU with integrated graphics. Audio is managed by the Realtek ALC S1200A codec with 7.1-channel surround sound, 24-bit/192 kHz playback, a 108 dB SNR on stereo line-out, and 103 dB SNR on line-in. Dedicated audio PCB layers, audio shielding, premium Japanese capacitors, and a de-pop circuit minimise interference. Optical S/PDIF output and five analogue 3.5 mm jacks are included on the rear panel. A Thunderbolt 3 header, SPI TPM header, two Aura RGB Strip headers, two Addressable Gen 2 RGB headers, and Aura Sync compatibility round out internal connectivity for enthusiast builds.
