The short version
The MPG X870E Carbon WiFi is MSI's upper-mid-range AM5 ATX board. It combines an 18+2+1 Duet Rail power design with 110A stages, two PCIe 5.0 M.2 slots, two USB4 ports, Wi-Fi 7 and a 5Gb plus 2.5Gb LAN pair. Tom's Hardware describes it as well priced against rivals and easy to build on thanks to tool-free EZ features. The main caveats are a BIOS that takes some getting used to and only four M.2 slots.
