Manufacturer description
The ASUS TUF Gaming B550-PLUS WiFi II is an ATX AM4 motherboard built for 3rd Gen AMD Ryzen builds that need PCIe 4.0 bandwidth without stepping up to an X570 board. Its 8+2 DrMOS power stage design, alloy chokes, and durable capacitors feed high-core-count Ryzen chips, while a fanless VRM and PCH heatsink keep the board silent under sustained load. Connectivity is where this TUF Gaming board separates itself: WiFi 6 (802.11ax), Bluetooth 5.2, and 2.5 Gb LAN with ASUS LANGuard cover wired and wireless gaming, and dual M.2 slots (one running PCIe 4.0 x4) let you pair a fast NVMe boot drive…
SpecPicks Verdict

Frequently Asked Questions
Does the ASUS TUF Gaming B550-PLUS WiFi II support 5000-series Ryzen CPUs?
The board is specified for AMD AM4 socket CPUs and marketed for 3rd Gen Ryzen. Support for any specific CPU depends on the installed BIOS version - check the ASUS CPU support list for your model before buying, and note the board includes BIOS Flashback so you can update firmware without a CPU installed.
How many M.2 slots does it have, and are they PCIe 4.0?
It has dual M.2 slots for NVMe SSDs. One of them runs at PCIe 4.0 x4; the second M.2 slot runs at a lower speed, so put your fastest drive in the PCIe 4.0 slot.
Do I need a separate WiFi card or network adapter?
No. WiFi 6 (802.11ax) and Bluetooth 5.2 are built in, along with a wired 2.5 Gb LAN port using ASUS LANGuard. Antennas and mounting hardware are typically included in the box - confirm on the product listing.
Is this motherboard rated well by buyers?
Yes - it is well-regarded by buyers, which is strong for a mid-range B550 board in this segment.
Can I run a display without a graphics card?
Yes, if you use a Ryzen APU with integrated graphics. The board provides HDMI 2.1 output at 4K 60Hz and DisplayPort 1.2. A CPU without integrated graphics requires a discrete GPU.
