The ASUS TUF GAMING B550-PLUS WIFI II is an ATX AM4 motherboard for builders using supported AMD Ryzen 3000, 4000 G-Series, or 5000-series processors who want PCIe 4.0 support, Wi-Fi 6, and 2.5Gb Ethernet for a gaming or general-purpose desktop.
Recommended For
- AM4 gaming-PC builders using a supported Ryzen processor who want Wi-Fi 6 and 2.5Gb Ethernet built into an ATX motherboard.
- PC builders adding multiple drives who need two M.2 slots plus six SATA ports for a mix of NVMe and SATA storage.
- Owners of a compatible AM4 system who want to reuse DDR4 memory and build around a supported Ryzen 3000- or 5000-series desktop processor.
- DIY builders who want onboard fan-control options and several headers for case fans, an AIO pump, and RGB or addressable-RGB lighting.
Real-World Use Scenarios
- Building an AM4 gaming PC with a supported Ryzen processor and a separate graphics card: the board provides a platform for the build, while gaming performance depends mainly on the processor, graphics card, and game settings.
- Setting up a desktop in a room without an Ethernet connection: its built-in Wi-Fi 6 lets the PC connect to a compatible wireless router without a separate Wi-Fi adapter; the included antennas need to be attached.
- Adding fast storage for games, applications, and files: the two M.2 slots allow a build to use NVMe SSDs alongside SATA drives, with the second M.2 slot sharing bandwidth with two SATA ports.
- Building a PC for gaming alongside work or creative hobbies: the ATX board’s expansion and connectivity options can accommodate a separate graphics card, multiple drives, and common peripherals in one desktop setup.
- Updating or troubleshooting a system when it cannot boot normally: BIOS FlashBack provides a way to update the BIOS using the board’s designated USB port and button, following ASUS’s instructions.
