Our take on the Asrock Phantom Gaming 4 AMD B550M Micro ATX Motherboard

The ASRock B550M Phantom Gaming 4 is a micro-ATX motherboard for AMD Ryzen 3000 and 5000 processors on socket AM4. It stands out for its low price, dual M.2 slots, and 2.5GbE LAN, but it cuts corners on VRM cooling and fan headers. It suits budget builders who want PCIe 4.0 support and a compact system without overclocking ambitions. Compared with pricier B550 boards, it lacks USB-C and has weaker power delivery, but covers the basics for most users.
