Placa-mãe MSI B850 GAMING PLUS WIFI ATX — AMD B850, Socket AM5, DDR5, 4x DIMM, Wi‑Fi 7, 5Gb LAN, 3x M.2, HDMI 2.1

The B850 GAMING PLUS WIFI is a motherboard engineered for gamers using AMD Ryzen™ 9000 series processors, offering extensive connectivity and an integrated Wi‑Fi 7 solution. It combines PCIe 5.0 support, 5G LAN, supplemental PCIe power and MSI's EZ DIY features to enable continuous 24/7 operation while meeting the needs of demanding gaming and AI workloads.

Advantages

The board uses a 12+2+1 Duet Rail Power System with digital VRM and 8 + 8‑pin CPU power connectors to provide stable delivery under heavy loads. Enhanced cooling elements such as an extended heatsink, heavy plated VRM heatsink, enlarged chipset heatsink and M.2 Shield Frozr improve heat dissipation for sustained performance. High‑quality 7W/mK thermal pads and additional choke pads further support thermal stability. Integrated high‑bandwidth, low‑latency networking with full‑speed Wi‑Fi 7 and 5G LAN ensures fast data transfer for competitive play.
