ASROCK A520M/Ac DDR4 AMD Motherboard

The ASRock A520M-AC is a Micro ATX form factor motherboard built around the AMD A520 chipset, designed to support AMD AM4 socket processors including 3rd Gen AMD Ryzen (3000 Series) and 4000 Series processors. It provides a reliable and feature-rich foundation for compact desktop builds that demand wireless connectivity and fast storage without a large footprint. One of the standout inclusions is the built-in dual-band 802.11ac WiFi module, supporting both 2.4GHz and 5GHz wireless bands along with Bluetooth 4.2. This is delivered via a dedicated M.2 Key-E vertical socket on the rear I/O, keeping the primary expansion slots free. For wired networking, a Realtek RTL8111H Gigabit LAN controller provides stable 10/100/1000Mbps Ethernet connectivity. Storage options are well covered. The board includes an Ultra M.2 slot supporting PCIe Gen3 x4 speeds up to 32Gb/s as well as SATA3 6Gb/s M.2 modules, giving users flexibility for both NVMe SSDs and SATA-based M.2 drives. Four SATA3 6.0Gb/s connectors are also present, and RAID modes 0, 1, and 10 are supported. The board supports two DDR4 memory slots in dual-channel configuration, with a maximum capacity of 64GB. Display output is provided through a single HDMI port supporting 4K resolution at 60Hz, suitable for use with processors that include integrated graphics. Audio is handled by a Realtek ALC887 codec delivering 7.1-channel HD audio, with rear-panel jacks for line-in, front speaker, and microphone. Expansion slots include one PCIe 3.0 x16 slot and one PCIe 3.0 x1 slot. The board also features ASRock Full Spike Protection to guard sensitive components against unexpected voltage fluctuations, and ASRock Live Update & APP Shop for driver and firmware management. The PCB is constructed using High Density Glass Fabric and features a Sapphire Black finish.
