    Great motherboard with Real WiFi 7 (320 MHz)

    Really happy with this motherboard. The build quality is excellent and setup was easy. Everything worked immediately without any fuss. The WiFi 7 actually delivers the 320 MHz bandwidth they advertise, got 3.4 Gbps and there is a desk and a wall between the PC and the router (Access point), unlike some other boards (starting with A, ending with S) I've tried which only had 160 MHz :/ . With PCIe 5.0 and several fast M.2 slots, it should handle upgrades to come. The BIOS is easy to use and I had no trouble getting my RAM running at full speed. I like the clean design and all the connectivity options - lots of USB ports. No strange issues with my Ryzen processor or Radeon graphics card. Temperatures stay reasonable, it runs quietly, and building with it was straightforward (first time since the being box area for that I did a build) If you need a solid AM5 motherboard that covers all the essentials without cutting corners on quality, this one's worth considering. I'd definitely recommend it.

    MSI B850 - Solid and feature-packed motherboard

    I bought this motherboard recently and I’m very satisfied. The VRM quality is excellent and keeps everything stable, even with demanding CPUs like the Ryzen 7 9800X3D. Another highlight is storage: it has two PCIe 5.0 M.2 slots, which makes it fully ready for future ultra-fast SSDs. Installation was also smooth thanks to MSI features like the EZ Debug LED and the tool-free M.2 design, which really help during setup. On top of that, audio quality is great (ALC4080) and connectivity is complete: Wi-Fi 7, Bluetooth 5.4, and 2.5GbE LAN. Overall, it’s a well-balanced, modern, and future-proof board. Definitely worth the investment.
