Verdict

The ASRock B550M Pro4 is a feature-rich Micro-ATX motherboard for AMD Ryzen (AM4) processors, featuring a robust 8-power phase design, PCIe 4.0 support for GPUs and NVMe SSDs, and dual M.2 slots (one Hyper M.2 PCIe Gen4 x4). It is highly regarded for its excellent price-to-performance ratio, featuring robust heatsinks for VRMs, onboard RGB headers, USB 3.2 Gen2 Type-A/C ports, and a pre-installed I/O shield, making it great for budget-to-midrange builds. However, it lacks built-in Wi-Fi and has limited fan headers, which may require splitters for more complex cooling setups.
