Description

The ASUS PRIME B650M-A II-CSM brings AMD's B650 chipset to a compact micro-ATX format, making it an excellent choice for builders who need modern AM5 platform features in a smaller footprint. This board supports the full range of AMD Ryzen 7000 series processors and handles DDR5 memory up to 6400 MHz across four DIMM slots, with a maximum capacity of 128 GB. The inclusion of both ECC and non-ECC memory compatibility gives users flexibility for workstation or gaming builds.

Connectivity options are comprehensive for a mainstream board, featuring 2.5 Gigabit Ethernet for fast network performance alongside multiple display outputs including DisplayPort, HDMI, and VGA for versatile monitor setups. USB connectivity spans both front and rear, with USB 3.2 Gen 2 ports at the back and a modern USB 3.2 Gen 1 Type-C connector on the front panel. PCIe 5.0 M.2 support ensures compatibility with the latest high-speed NVMe drives.

ASUS includes practical features like BIOS FlashBack for easy firmware updates without a CPU installed, plus Aura Sync RGB lighting support through the onboard LED header. The board supports memory overclocking profiles to help DDR5 kits reach their rated speeds, and the micro-ATX size makes it suitable for compact cases while retaining full-sized expansion capabilities. An I/O shield comes included along with the standard documentation and mounting hardware.
