AM4 Micro-ATX Board for Ryzen 2000 3000 5000

This ASRock B450M/AC R2.0 motherboard uses the AMD Promontory B450 chipset and an AM4 socket. It supports Ryzen 2000, 3000 and 5000 Series desktop processors. The Micro-ATX form factor fits smaller cases while providing four DDR4 slots and integrated 802.11ac Wi-Fi.

Check CPU Cooler Clearance and BIOS Version

Verify that your CPU cooler mounting holes match the AM4 layout and that the cooler height suits your case. Ryzen 5000 Series chips may require a BIOS update before first boot; confirm the board ships with a compatible revision or prepare a supported CPU for the update. Ensure your power supply has the 8-pin EPS connector for the 10 power phase design.

Dual Channel DDR4 up to 128GB with Ultra M.2 and RGB

Four 288-pin slots run dual-channel DDR4 up to 3200 MHz and a maximum of 128 GB. One Ultra M.2 socket accepts 2242 2260 2280 drives at PCIe Gen3 x4 speeds. A second M.2 Key E slot holds the bundled Wi-Fi module. Two RGB headers and one addressable RGB header drive strips up to 80 LEDs at 5 V or standard 5050 strips at 12 V. Realtek ALC892/897 provides 7.1 channel audio and RTL8111H handles wired LAN.
