AM4 builders who want full ATX form factor with WiFi 6 at the lowest price in the ATX category of this comparison will find the B550 Eagle WIFI6 the entry point at $91 with 663 reviews. The ATX layout provides an additional PCIe x1 expansion slot, more SATA ports for storage arrays, and better cable routing in mid-tower cases compared to the mATX alternatives — without a significant price premium. WiFi 6 (802.11ax) is the standard for current routers and provides adequate performance for gaming, streaming, and 4K video. VRM is Eagle-tier — appropriate for Ryzen 5 5600X through 5700X without throttling; not the board for sustained Ryzen 9 overclocking. For a mid-range Ryzen 5000 ATX build where budget and WiFi access matter, this is the sensible starting point.
