MSI B840 GAMING PLUS WIFI ATX Motherboard | AM5 | 4x DDR5 Slots | Wi-Fi 7
Description
The MSI B840 GAMING PLUS WIFI is a full-size ATX motherboard built around AMD's B840 chipset, targeting mainstream builders who want solid performance without premium pricing. Supporting AMD's AM5 socket, it works with Ryzen 7000, 8000, and 9000 series processors, making it compatible with both current and next-generation AMD CPUs. The black PCB and gaming-focused branding signal its intent as a reliable foundation for gaming and productivity builds.
Memory support extends up to 256GB across four DDR5 DIMM slots, with speeds reaching 8000MHz when overclocked - more than enough bandwidth for demanding applications and future upgrades. The board includes two M.2 slots supporting PCIe 4.0 storage, with the second slot accommodating longer 22110 drives for maximum flexibility. Connectivity stays current with Wi-Fi 7 wireless, 2.5 Gigabit Ethernet, and a single PCIe x16 slot for graphics cards. Four SATA ports handle traditional storage drives.
RGB enthusiasts get three dedicated LED headers to coordinate lighting across components, while the single CPU fan connector and water pump header provide cooling flexibility. The motherboard supports both XMP and AMD EXPO memory profiles for easy performance tuning. Standard inclusions cover the essentials: I/O shield, SATA cables, M.2 mounting hardware, and a comprehensive user guide to get your system running quickly.
