Verdict

The ASRock A520M Pro4 is a Micro ATX motherboard for the AMD AM4 socket, featuring an 8-phase power design and support for Ryzen 3000 to 5000 series processors. It includes four DDR4 slots supporting up to 128GB at 4733+(OC) MHz, two M.2 slots (one Ultra M.2 PCIe Gen3 x4), and comprehensive video outputs including HDMI 2.1 (4K@60Hz), DisplayPort 1.4, and D-Sub. Key pros include its robust VRM cooling for an entry-level board, a dedicated M.2 Key E slot for Wi-Fi modules, and a premium Realtek ALC1200 7.1 channel audio codec. However, it lacks PCIe 4.0 support, does not allow for CPU overclocking, and requires a separate Wi-Fi card to utilize the wireless slot.
