Verdict
The ASRock B550 Pro4 is a basic mid-range board with 8 power phases and fanless chipset cooling, but its single M.2 heatsink and Gigabit Ethernet limit it.

Third-party reviews

What customers like about ASRock B550 Pro4

  • Excellent value for money, often cited as a top choice for budget-conscious AM4 builds
  • Generous storage options, featuring two M.2 slots (one with a Gen4 x4 shield) and six SATA3 ports
  • High-quality onboard audio for its price point, utilizing the Realtek ALC1200 codec
  • Ample connectivity with multiple fan headers, RGB/Addressable RGB headers, and a dedicated M.2 slot for Wi-Fi
  • Solid aesthetics with a silver/white heat sink design that fits many themed builds
  • Includes helpful troubleshooting features like Post Status Checker (Debug LEDs)

What customers don't like about ASRock B550 Pro4

  • Lacks a BIOS Flashback button, which can make initial setup difficult if a BIOS update is needed for newer CPUs
  • The secondary M.2 slot only supports PCIe Gen3 x2 speeds, offering half the bandwidth of some competitors
  • No integrated Wi-Fi or Bluetooth, requiring a separate purchase of an M.2 Wi-Fi card
  • VRM design is considered mediocre and may not be suitable for heavy overclocking or high-end Ryzen 9 CPUs
  • Lacks an internal USB Type-C front panel header, which is increasingly standard on modern cases
  • Some users reported reliability issues, including boards arriving DOA or failing after a few months of use

Verdict

The ASRock B550 Pro4 is a budget-friendly ATX motherboard designed for AMD AM4 Ryzen 3000 to 5000 series processors, featuring a solid 8-phase power delivery system with 50A power chokes and an XXL aluminum alloy heatsink. Key specifications include four DDR4 slots supporting up to 128GB at 4733+MHz (OC), a primary PCIe 4.0 x16 steel-reinforced slot, and dual M.2 storage options with one supporting high-speed PCIe Gen4 x4. Main pros include its surprisingly high-quality Realtek ALC1200 audio codec, a dedicated M.2 Key E slot for WiFi modules, and extensive rear I/O connectivity featuring USB 3.2 Gen2 Type-A and Type-C ports. However, common cons include the lack of an integrated I/O shield, no onboard WiFi included by default, and a BIOS that lacks a physical flashback button for easy updates without a compatible CPU.
