The ASUS TUF GAMING B850-PLUS WIFI is an ATX AM5 motherboard for Ryzen 7000, 8000, and 9000 desktop processors, suited to gaming and performance-focused PC builds that need DDR5, a PCIe 5.0 graphics slot, three M.2 slots, Wi-Fi 7, and 2.5Gb Ethernet.
Recommended For
- AM5 gaming-PC builders pairing a Ryzen 7000, 8000, or 9000 desktop CPU with a discrete GPU who want a full-size ATX board with Wi-Fi and a PCIe 5.0 graphics slot. Reviews found gaming results broadly similar across tested B850 boards, so the motherboard is better viewed as a platform choice than a way to raise game frame rates by itself.
- Builders using several PCIe add-in cards alongside a large GPU who want more slot flexibility than many B850 boards provide; TweakTown specifically highlights the board’s expansion-slot layout as a reason to choose it.
- AM5 users who need up to three onboard M.2 drives—including one PCIe 5.0 drive with Ryzen 7000 or 9000 processors—and want heatsinks and SATA ports for a desktop storage setup.
- Workstation and gaming builders running a high-core-count Ryzen CPU at stock settings or with moderate tuning; TweakTown tested a Ryzen 9 9950X and reported that the board handled it under sustained load with airflow around the CPU socket.
- Desktop builders who want onboard Wi-Fi 7, Bluetooth, and 2.5Gb Ethernet, with BIOS FlashBack and diagnostic features that can help during assembly and troubleshooting.
