The MSI PRO B840M-P WIFI6E is an mATX motherboard built on the AMD B840 chipset for the Socket AM5 platform. It is engineered to support AMD Ryzen 9000, 8000, and 7000 Series desktop processors, providing a stable foundation for productivity-oriented systems. The board features four DDR5 UDIMM slots that operate in a dual-channel configuration, supporting memory overclocking speeds up to 8000+ MT/s. Its compact mATX form factor allows for installation in smaller chassis while maintaining essential connectivity and expansion capabilities.
For expansion, the board includes a primary PCIe 4.0 x16 slot for a graphics card and a secondary PCIe 3.0 x1 slot for other peripherals. Storage options consist of two M.2 slots for high-speed NVMe drives and four SATA III ports for conventional storage devices, with RAID support for both interface types. Integrated networking is handled by a 2.5G LAN controller and a Wi-Fi 6E module, which also provides Bluetooth 5.3 connectivity. The rear I/O panel offers a range of USB ports, including Type-A and Type-C, alongside an HDMI 2.1 video output.
