The ASUS Prime B550M-A WiFi II is a micro-ATX AM4 motherboard built for AMD Ryzen 5000, 5000 G, 4000 G and 3000 series chips. It pairs a robust power design and comprehensive cooling with onboard Wi-Fi, so a mid-range build needs no separate wireless card. The ASUS UEFI BIOS offers a simplified mode for beginners and an Advanced mode with search for tweakers. It suits budget-conscious builders who want a compact board with wireless networking and room to tune, rather than the extra PCIe lanes and rear I/O of pricier B550 boards.

The ASUS Prime B550M-A Wi-Fi II is a Micro-ATX motherboard with an AM4 socket. It supports AMD Ryzen 5000 Series, 5000 G-Series, 4000 G-Series and 3000 Series processors.
For cooling, it has a VRM heatsink with a thermal pad under it, plus multiple onboard heatsinks. Each chassis fan header supports 4-pin PWM and DC fans. Each header can reference three thermal sensors, and a dedicated integrated circuit protects it from overheating and overcurrent. Fan settings can be configured in Fan Xpert 2+ software or in the UEFI BIOS.
The UEFI BIOS has an EZ Mode with guided wizards, drag-and-drop functions, graphical fan control and one-click EZ XMP for DRAM. Its Advanced Mode includes a search function and ASUS User Profile for moving settings between BIOS versions. Aura Sync controls RGB lighting for strips connected to the onboard RGB headers, and Aura can be switched off for the board's LEDs.
