Verdict

The ASRock B550 Phantom Gaming 4 is an ATX motherboard for the AM4 socket that supports AMD Ryzen 3000, 4000 G-Series, and 5000 series desktop processors. It features an 8-phase Digi Power VRM design, four DDR4 slots supporting up to 128GB at overclocked speeds of 4733+ MHz, and a dual M.2 configuration including one Hyper M.2 (PCIe Gen4 x4) slot for high-speed storage. Key advantages include its budget-friendly entry into PCIe 4.0 technology, a reinforced steel PCIe slot for heavy GPUs, and extensive RGB customisation via Polychrome Sync headers. However, notable drawbacks include the absence of a USB-C port on the rear or front panel, a lack of a BIOS Flashback button for easy updates, and the use of a basic Realtek ALC1200/ALC897 audio codec compared to higher-end models.
