MSI B850M Gaming Wifi7 DDR5 AMD Motherboard

The MSI B850M Gaming WiFi 7 is a micro-ATX motherboard built on the AMD B850 chipset, designed for the AM5 socket and compatible with AMD Ryzen 9000, 8000, and 7000 series desktop processors. It delivers a robust feature set for gamers and power users who want next-generation connectivity in a compact form factor. At the heart of its connectivity is Wi-Fi 7 (IEEE 802.11be), supporting tri-band operation across 2.4 GHz, 5 GHz, and 6 GHz (160 MHz) with MU-MIMO and Multi-Link Operation (MLO), achieving wireless speeds up to 2.9 Gbps. Bluetooth 5.4 is also included. For wired networking, the Realtek 8126 controller provides a 5G LAN port, suitable for high-throughput transfers and latency-sensitive online gaming. Memory is handled by two DDR5 UDIMM slots supporting up to 128 GB total, with JEDEC speeds from 4800 to 5600 MT/s and overclocking headroom reaching DDR5-8200+ MT/s (1DPC 1R configuration) via AMD EXPO and MSI Memory Boost technology. Dual-channel mode and Non-ECC unbuffered memory are supported, as is CUDIMM in Clock Driver bypass mode. Storage expansion is covered by two M.2 slots: M.2_1 (CPU-direct) runs at PCIe 5.0 x4 for Ryzen 9000/7000 processors, delivering peak NVMe throughput, while M.2_2 (CPU-direct) supports PCIe 4.0 x4. Four SATA 6 Gbps ports round out storage options. RAID 0, 1, and 10 are available for SATA, and RAID 0/1 for M.2 NVMe devices. The primary PCIe x16 slot (PCI_E1) runs at PCIe 5.0 x16 with Ryzen 9000/7000 series CPUs, while a secondary PCIe 4.0 x4 slot (from chipset) accommodates add-in cards. The VRM is a 7+2+1 P-PAK digital power system with an 8-pin CPU connector, extended heatsinks, and MOSFET thermal pads rated at 7 W/mK, designed for sustained heavy workloads. Display output is provided by HDMI 2.1 (up to 4K 60 Hz) and DisplayPort 1.4 (up to 4K 60 Hz) on the rear panel for systems using integrated graphics. Audio is delivered by a Realtek ALC897 codec supporting 7.1-channel high-definition audio. USB connectivity spans rear and front headers: rear panel includes 2x USB 2.0, 3x USB 5 Gbps Type-A, and 1x USB 5 Gbps Type-C; front headers add 4x USB 2.0, 2x USB 5 Gbps Type-A, and 1x USB 10 Gbps Type-C. RGB support includes three Addressable V2 (JARGB_V2) headers and one standard JRGB header. EZ DIY features include EZ M.2 Clip II, EZ PCIe Clip II, EZ Antenna, Flash BIOS Button, and Clear CMOS Button. The board measures 226 mm x 243.84 mm (mATX) and supports Windows 11 64-bit.
