MSI Pro B840-S EVO WIFI6E ATX Motherboard | AM5 | 4x DDR5 Slots | Wi-Fi 6E
Description
The MSI Pro B840-S EVO WIFI6E brings AMD's B840 chipset to the ATX form factor, targeting mainstream builders who want room for expansion without paying enthusiast-tier prices. This AM5 socket board supports the latest AMD Ryzen 7000, 8000, and 9000 series processors, making it compatible with current and next-generation CPUs. The ATX layout provides ample space for components and good airflow in mid-tower and full-tower cases.
Memory support extends to DDR5 with speeds up to 8000 MHz when overclocked, across four DIMM slots that can accommodate up to 256 GB total capacity. Three M.2 slots handle fast NVMe storage, all running at PCIe 4.0 speeds with support for drives up to 22110 length on the second slot and standard 2280 on the first. The single PCIe x16 slot runs at Gen 4.0 speeds for modern graphics cards, while connectivity includes built-in Wi-Fi 6E and 2.5 Gigabit Ethernet for fast wired and wireless networking.
MSI includes practical features like three RGB LED headers for custom lighting setups, dedicated connectors for both CPU fans and water pump systems, and four SATA 6G ports for additional storage drives. The board supports both XMP and EXPO memory profiles for easy DDR5 overclocking, taking the guesswork out of achieving rated memory speeds. An I/O shield, user manual, and necessary installation hardware come in the box to get your build started.
