MSI PRO B860M-A WIFI mATX Motherboard | LGA1851 | 4x DDR5 Slots | Wi-Fi 7
Description
The MSI PRO B860M-A WIFI brings Intel's latest LGA1851 socket to the compact mATX form factor, making it an excellent choice for builders who need modern platform features without the bulk of a full-size board. Built around Intel's B860 chipset, this board supports the newest Intel Core Ultra Series 2 processors and offers surprising capability for its mainstream positioning. The inclusion of Wi-Fi 7 and Bluetooth 5.4 ensures cutting-edge wireless connectivity, while the 5G LAN provides exceptionally fast wired networking that goes well beyond standard gigabit speeds.
Memory support is particularly strong, with four DDR5 slots capable of handling up to 256GB at speeds reaching 8800MHz when overclocked. Three M.2 slots provide ample storage expansion - one PCIe 5.0 slot for the fastest NVMe drives, plus two PCIe 4.0 slots for additional high-speed storage. The board also includes four PCIe x16 slots (one Gen 5.0, three Gen 4.0), giving you flexibility for graphics cards and expansion cards. Traditional SATA connectivity rounds out the storage options with four ports for older drives.
RGB enthusiasts will appreciate the three RGB LED pin headers that let you sync lighting across multiple components. The board includes practical features like a water pump connector alongside the standard CPU fan header, making it suitable for both air and liquid cooling setups. MSI includes the essential accessories in the box - I/O shield, SATA cables, M.2 mounting hardware, and a comprehensive user guide to get your build up and running smoothly.
