ASUS TUF Gaming B550 Plus Wifi II DDR4 AMD Motherboard

The ASUS TUF Gaming B550-Plus WiFi II is an ATX-form-factor motherboard (30.5 cm x 24.4 cm) built on the AMD B550 chipset with an AM4 socket, supporting AMD Ryzen 5000 Series, 5000 G-Series, 4000 G-Series, and 3000 Series desktop processors. It is designed to deliver dependable gaming performance through a combination of military-grade TUF components, an 8+2 DrMOS power stage configuration, and ASUS Digi+ VRM digital power control — all working together for stable voltage delivery during demanding workloads. Memory capacity is handled by four DDR4 DIMM slots supporting up to 128 GB in a dual-channel configuration. The board accepts DDR4 speeds from 2133 MHz up to 4866 MHz (via overclocking), and ECC memory support varies by installed CPU. For storage, two M.2 Key-M slots are included: M.2_1 supports PCIe 4.0 x4 (with Ryzen 5000/3000 non-G CPUs) or PCIe 3.0 x4 (with G-Series APUs), plus SATA mode; M.2_2 operates at PCIe 3.0 x4 via the B550 chipset. Both M.2 slots accept drives up to 22110 form factor and are covered by aluminum heatsinks. Six SATA 6 Gb/s ports round out storage connectivity, with RAID 0, 1, and 10 support available. Expansion is served by one primary PCIe x16 slot — running at PCIe 4.0 x16 with Ryzen 5000/3000 non-G CPUs or PCIe 3.0 x16 with G-Series processors — plus one chipset PCIe 3.0 x16 slot (x4 electrical) and three PCIe 3.0 x1 slots. Wireless connectivity uses a 2×2 Wi-Fi 6 (802.11 a/b/g/n/ac/ax) module covering 2.4 GHz and 5 GHz bands, paired with Bluetooth 5.2. Wired networking is handled by a Realtek 2.5 Gb Ethernet controller with ASUS TUF LANGuard surge protection. The rear I/O panel provides 14 ports in total: 2× USB 3.2 Gen 2 (1× Type-A, 1× Type-C), 4× USB 3.2 Gen 1 Type-A, 2× USB 2.0 Type-A, DisplayPort 1.2, HDMI 2.1 (4K@60 Hz), 5× audio jacks, optical S/PDIF out, and a BIOS FlashBack button. Audio is powered by a Realtek HD codec delivering 7.1 surround sound with 24-bit/192 kHz playback, dedicated audio PCB layers, and Japanese audio capacitors. AURA Sync RGB lighting is supported via two AURA RGB headers and two Addressable Gen 2 headers. The UEFI BIOS (256 Mb Flash ROM, AMI) includes CrashFree BIOS 3, EZ Flash 3, and EZ Mode for accessible tuning. A 3-year warranty is included.
