Verdict

The ASRock B550M Phantom Gaming 4 is a budget-friendly Micro-ATX motherboard built on the AMD AM4 socket, supporting Ryzen 3000, 4000 G-Series, and 5000 Series desktop processors. Key specifications include an 8-power phase design with 50A chokes for stable power delivery, four DDR4 DIMM slots supporting up to 128GB at 4733+ MHz (OC), and a dual M.2 setup featuring one Hyper M.2 PCIe Gen4 x4 slot and one PCIe Gen3 x2/SATA3 slot. Its main pros are the inclusion of PCIe 4.0 support for modern GPUs/SSDs, dual graphics outputs (HDMI 2.1 and DisplayPort 1.4), and Polychrome RGB synchronization, all at an accessible price point. Notable cons include the lack of a dedicated BIOS Flashback button, which can complicate initial setup with newer CPUs, and a relatively limited back I/O that lacks USB Type-C and high-speed USB 3.2 Gen2 ports.
