Brand: Asus
SKU: 6911

Manufacturer: Asus

The Asus TUF Gaming B850M-Plus Wi-Fi7 is a Micro-ATX motherboard built around the AM5 socket and B850 chipset, offering a compact yet capable platform for AMD-based builds. It features Wi-Fi 7 (802.11be) along with Bluetooth 5.4, making it well-suited for setups where wireless connectivity is a priority. RGB lighting, dual BIOS, and an easy CMOS reset button round out the user-friendly design touches, and the board carries a three-year warranty.

On the memory side, the board supports DDR5 across four slots with a maximum capacity of 256 GB and overclocked speeds reaching up to 8000 MHz in a dual-channel configuration. Expansion options include one PCIe 5.0 x16 slot and three M.2 sockets alongside four SATA 3 connectors, with RAID 0, 1, 5, and 10 all supported. The rear I/O provides three USB 3.2 Gen 2 Type-A ports, one USB 3.2 Gen 2x2 Type-C port, four USB 3.2 Gen 1 Type-A ports, HDMI 2.1, one DisplayPort output, and a single RJ45 Ethernet port, while the onboard audio delivers a 120 dB signal-to-noise ratio over a 7.1-channel layout.

Pros

Supports Wi-Fi 7 along with four older Wi-Fi standards, covering a wide range of wireless connectivity needs
Four DDR5 slots allow up to 256 GB of memory with overclocked speeds reaching 8000 MHz
Three M.2 sockets combined with four SATA 3 connectors provide flexible storage configuration options
Dual BIOS and an easy CMOS reset button simplify recovery from failed updates or misconfigurations
A single PCIe 5.0 x16 slot ensures compatibility with the latest generation expansion cards
RAID 0, 1, 5, and 10 support offers meaningful flexibility for storage redundancy and performance setups

Cons

Micro-ATX form factor limits the total number of expansion slots, with only one PCIe x1 slot alongside the primary x16 slot
No USB 4 or Thunderbolt ports are available on the rear I/O
ECC memory is not supported, ruling out use cases that require error-correcting RAM
No S/PDIF output is present for digital audio passthrough to external receivers
No TPM connector is available on the board

Who is this for?

This board is a practical fit for AMD Ryzen builders working within a compact desktop footprint who still want access to modern connectivity and storage options. The Wi-Fi 7 support and Bluetooth 5.4 make it well-suited for wireless-focused setups where a clean, cable-light build is preferred. Users planning to run fast DDR5 memory kits, multiple NVMe drives across the three M.2 sockets, or a current-generation GPU through the PCIe 5.0 x16 slot will find the feature set accommodating. The RAID 0, 1, 5, and 10 support also makes it a reasonable choice for home or small office environments where basic storage redundancy is a requirement.

Who is this NOT for?

This board is not a strong match for users who rely on Thunderbolt or USB 4 connectivity, as neither is available on the rear I/O, which could be limiting for those working with high-bandwidth external devices or docking stations. The Micro-ATX form factor and limited expansion slot count make it a poor fit for builds that require multiple full-size PCIe cards simultaneously. Additionally, users in professional or workstation environments where ECC memory is a requirement for data integrity will need to look elsewhere, as this board does not support error-correcting RAM.
