What motherboard suits Ryzen 5 5600XT, and how should power delivery, memory, and ports be balanced?

  The 5600XT runs AM4 with DDR4. For a new build, B550 supports PCIe 4.0 graphics and M.2; if you already own a B450, check its BIOS support list first; X570 is only worth it with many PCIe devices.

  For gaming, a stable B550 with the USB/M.2 you need is enough; add VRM cooling budget only for sustained compiling or rendering. The platform is winding down, so keep investment proportionate.
