Our verdict

A well-connected, stable AM5 board for the price, with real reports of smooth Ryzen 9000-series builds, though a first-boot display quirk and inconsistent warranty support are worth knowing about first.

Overview

The TUF Gaming B850M-PLUS WiFi is an AM5 mATX motherboard for AMD Ryzen 7000/8000/9000 desktop builds, with 14+2+1 80A power stages, three M.2 slots, PCIe 5.0, Wi-Fi 6E and 2.5Gb LAN aimed at DIY gaming and workstation builds.

It sits in ASUS's mid-tier TUF Gaming line, so the power delivery and connectivity outpace typical budget boards while staying short of the flagship ROG lineup. Buyers running high-speed DDR5 report stable overclocks, though a few flag one recurring first-boot quirk with a discrete GPU installed and mixed experiences with ASUS's warranty support.

  • AM5 socket for Ryzen 7000/8000/9000 series
  • 14+2+1 80A DrMOS power stages on an 8-layer PCB
  • Three M.2 slots (one PCIe 5.0, two PCIe 4.0)
  • Wi-Fi 6E, 2.5Gb LAN, USB Type-C up to 20Gbps

Who it's for

Fits builders assembling an AM5 gaming or general-use PC who want mATX space savings without giving up PCIe 5.0, three M.2 slots or Wi-Fi 6E. Less ideal for anyone planning to fill every M.2 slot alongside heavy case cooling near the GPU in a compact chassis.

Pros and cons

Pros
  • 14+2+1 80A power stages kept high-speed DDR5 stable
  • Three M.2 slots plus PCIe 5.0 x16 support
  • Wi-Fi 6E, 2.5Gb LAN and dual-speed USB-C
  • BIOS described as user-friendly for both basics and overclocking

Performance notes

One recurring issue: with a discrete GPU installed, the first boot can fail to output video until the monitor is temporarily connected to the rear I/O and the GPU is reseated, a workaround more than one high-RAM-speed build needed. The front M.2 slot placement also means the first PCIe expansion slot competes with an installed M.2 drive, which can limit cooling clearance around the graphics card in compact builds.
