Our take on the ASUS Prime B550M-A WiFi II AMD AM4 Micro ATX Motherboard
The ASUS Prime B550M-A WiFi II is a micro ATX motherboard for AMD AM4 processors, with built-in WiFi 6 and Bluetooth 5.2 so a build needs no separate wireless card. It has one PCIe 4.0 x16 slot for a graphics card, a second x16-length slot wired at PCIe 3.0, two M.2 slots and four DDR4 DIMM slots. It suits mid-range Ryzen builds where a compact board with onboard wireless matters more than premium overclocking hardware. Against pricier B550 boards it gives up beefy VRM heatsinks, POST code display and extra USB, but covers the essentials for a gaming or work PC.
- WiFi 6 and Bluetooth 5.2 built in
- PCIe 4.0 x16 slot for the graphics card
- Two M.2 slots, one with a heatsink
- Four DDR4 slots for up to 128GB
- BIOS FlashBack updates without a CPU

What reviewers say
Owners of ASUS Prime B550 boards generally find them easy to build with and reliable once running, and value the onboard WiFi. Criticisms focus on the light VRM heatsinks and limited connectivity rather than stability.
- WiFiPraisedOwners say the onboard WiFi 6 works reliably and saves buying an add-in card.
- SetupPraisedBuilders describe the BIOS and layout as easy to work with on a first build.
- VRM coolingCriticisedReviewers note the small VRM heatsinks get hot with power-hungry Ryzen chips.
Questions and answers
- Does it work with Ryzen 5000 processors out of the box?
- Most units ship with a BIOS that supports Ryzen 5000, but older stock may need an update. BIOS FlashBack lets you update from a USB drive without a CPU installed.
- Is WiFi 6 fast enough for gaming?
- WiFi 6 handles online gaming and streaming well on a good router. For the lowest latency, a wired Ethernet connection is still better.
- Can I fit two graphics cards?
- There are two x16-length slots, but only the top one runs at PCIe 4.0. The second is wired at PCIe 3.0, so multi-GPU setups are limited.
- How much memory does it support?
- Four DDR4 DIMM slots take up to 128GB. Ryzen 5000 and 3000 CPUs run memory at their rated speeds, and the BIOS has DOCP profiles for one-step setup.
- Does it fit a standard micro ATX case?
- Yes, it uses the micro ATX form factor, which fits most mid-tower and smaller cases. Check clearance for a long graphics card and a tall CPU cooler.
- What is in the box?
- The board, a WiFi antenna, SATA cables, an I/O shield and mounting screws. A printed quick-start guide is included.
