Verdict

The MSI B840 Gaming Plus WiFi is an ATX motherboard featuring the entry-level AMD B840 chipset and AM5 socket, supporting AMD Ryzen 9000, 8000, and 7000 series processors. It is equipped with a 7+2+1 phase power system, four DDR5 slots supporting up to 256GB at 8000+ MT/s (OC), and a PCIe 4.0 x16 slot with Steel Armor for durable GPU support. Key characteristics include dual M.2 Gen4 x4 slots with Shield Frozr II cooling, next-gen Wi-Fi 7, 2.5G LAN, and high-speed USB 10Gbps Type-C connectivity. Its main pros are the cutting-edge wireless networking and user-friendly 'EZ DIY' features like tool-less M.2 clips and a pre-installed I/O shield. However, significant cons include the lack of CPU overclocking or PBO support due to chipset limitations and the absence of PCIe 5.0 lanes for storage or graphics.
