Name: Asus TUF Gaming B850-Plus WiFi
Brand: Asus
SKU: 2193

Manufacturer: Asus

The Asus TUF Gaming B850-Plus WiFi is an ATX form factor motherboard built around the AM5 socket and B850 chipset, designed for systems running DDR5 memory. It includes integrated wireless connectivity up to Wi-Fi 7 (802.11be) alongside Bluetooth 5.4, making it a well-connected option for desktop builds that benefit from wireless peripherals or network access without an add-in card. The board ships with a 3-year warranty and supports easy overclocking, with RGB lighting and a dual BIOS configuration for added resilience.

On the memory side, the board provides four slots capable of holding up to 192GB of DDR5 RAM across two channels, with standard speeds reaching 4000 MHz and overclocked profiles supported up to 8000 MHz. Storage connectivity includes three M.2 sockets and four SATA 3 ports, with full support for RAID 0, 1, 5, and 10 configurations. Expansion options cover one PCIe 5.0 x16 slot and one PCIe 4.0 x16 slot, complemented by two PCIe x1 slots. The rear I/O offers a mix of USB 3.2 Gen 2 and Gen 1 Type-A ports, one USB 3.2 Gen 2x2 Type-C port, HDMI 2.1, one DisplayPort output, and a single RJ45 Ethernet jack, alongside a 7.1-channel audio solution rated at 120 dB signal-to-noise ratio.

Pros

Supports Wi-Fi 7 alongside all previous Wi-Fi generations down to Wi-Fi 4, with Bluetooth 5.4 also built in, removing the need for a separate wireless card
Three M.2 sockets alongside four SATA 3 connectors give plenty of flexibility for mixing fast NVMe drives with traditional storage
DDR5 memory can be overclocked up to 8000 MHz across four slots, with a maximum capacity ceiling of 192GB
Dual BIOS provides a fallback in case of a failed firmware update, adding resilience for long-term use
Full RAID support across modes 0, 1, 5, and 10 suits users who want both performance striping and data redundancy options
The onboard audio delivers a 120 dB signal-to-noise ratio with 7.1-channel support and five connectors, making it capable for multi-speaker setups without a dedicated sound card

Cons

No USB 3.2 Gen 2 Type-C ports on the rear I/O, and no USB 4 ports of any speed are available
ECC memory is not supported, which limits the board for workloads that rely on error-correcting RAM
There is no dedicated BIOS reset button, making CMOS clearing less straightforward
No S/PDIF Out port is present, which may affect users who rely on optical or coaxial digital audio output
No TPM connector is available onboard for users who require a discrete TPM module

Who is this for?

This board is a solid fit for enthusiast desktop builders who want a future-ready AM5 platform with room to grow. Users who plan to push memory performance will appreciate the four DDR5 slots and overclocked RAM support up to 8000 MHz, while those building NVMe-heavy storage rigs will benefit from three M.2 sockets paired with full RAID support. The inclusion of Wi-Fi 7 and Bluetooth 5.4 makes it particularly well suited to setups where running a network cable is impractical, and the dual BIOS adds a layer of reliability that appeals to users who frequently experiment with firmware or overclocking settings.

Who is this NOT for?

This board is not a good match for users who need ECC memory support, such as those running workstations handling data-sensitive tasks where memory error correction is a requirement. The absence of USB 4 and Thunderbolt ports makes it a poor choice for users who rely on high-bandwidth external devices like fast external SSDs or professional docking stations that depend on those standards. Additionally, content creators or home theater users who need a digital audio output via S/PDIF for connection to external DACs or AV receivers will find this board lacking in that regard.
