Asus PRIME B840M-R DDR5 AM5 mATX Motherboard

The ASUS PRIME B840M-R is a micro-ATX motherboard designed for the AMD AM5 platform, supporting Ryzen 9000, 8000, and 7000 series processors. Its compact form factor is suitable for smaller cases while maintaining standard desktop functionality. The board uses DDR5 memory, with support for speeds up to 7600 MHz and unbuffered modules to help maintain low latency during use.

For storage, the board provides two M.2 slots and four SATA III connectors. It is powered via a standard 24-pin ATX connector and an 8-pin EPS CPU plug. The rear panel supports integrated graphics through HDMI and DisplayPort, meaning a discrete graphics card is not required. Networking is handled by a single Gigabit Ethernet port; this model does not include integrated Wi-Fi or Bluetooth. Cooling is supported by one primary CPU fan header and two chassis fan headers, while internal audio and front-panel headers allow for standard case integration.
