Product overview
GIGABYTE’s A520I AC is a Mini‑ITX AM4 motherboard announced on August 18, 2020 as part of the company’s AMD A520 lineup, with retail availability rolling out in late September 2020 in some regions. It sits in the A520 family for Ryzen 3000/5000 processors.
Positioned as an entry‑tier ITX option, it exists to deliver an affordable, compact AM4 platform. You get two DDR4 DIMM slots (up to 64 GB), a PCIe 3.0 x16 slot, one PCIe 3.0 x4 NVMe M.2 socket, four SATA 6 Gb/s ports, 1 GbE, and onboard 802.11ac Wi‑Fi. That mix suits space‑constrained builds like HTPCs or small gaming systems that don’t need heavy expansion and are friendly for first‑time builders. Notable: triple display outputs (DP + 2× HDMI) when paired with a Ryzen APU.
