Socket AM4 Mini ITX board

The GIGABYTE A520I AC is a Mini ITX motherboard built around the AMD A520 chipset and the AM4 socket. It supports 3rd Gen Ryzen and 3rd Gen Ryzen with Radeon Graphics processors, plus Ryzen 5000 Series after a BIOS update. The board provides two DDR4 slots for up to 64 GB of dual-channel memory and a single PCIe 3.0 x16 slot for a graphics card.

Compact builds with integrated graphics

This board suits builders who want a small system using an AM4 CPU with integrated graphics and do not need overclocking headroom. It also fits users who prefer a single M.2 NVMe drive and up to four SATA devices. Anyone needing CPU overclocking, multiple M.2 slots, PCIe 4.0 or more than one expansion card should choose a different chipset.

Build integration

The board needs a Mini ITX case, an SFX or SFX-L power supply and low-profile CPU cooler. Two DDR4 DIMMs fill the memory limit. One M.2 2280 slot and four SATA 6 Gb/s ports handle storage. Realtek GbE LAN and Intel Wi-Fi AC 3168 provide wired and wireless networking. DisplayPort 1.4 and HDMI outputs use the APU graphics, freeing the PCIe slot for a discrete GPU.

Questions about this item

Which AMD AM4 processor do I need already so the board can boot and let me update the BIOS for Ryzen 5000 support?

You need a 3rd Gen Ryzen or a 3rd Gen Ryzen with Radeon Graphics processor; the board only supports Ryzen 5000 Series after a BIOS update applied with one of those CPUs installed.

Will my existing DDR4-3200 memory run at its rated speed without manual tuning?

Yes — DDR4-3200 is a native JEDEC speed for both 3rd Gen Ryzen and 3rd Gen Ryzen with Radeon Graphics, so the board will run it at 3200 MHz automatically.

How can I confirm the Intel Wi-Fi AC 3168 module is connected and running at up to 433 Mbps after I build the system?

Open Device Manager, verify the adapter appears without errors, then check the link speed in the Wi-Fi status window; it should report up to 433 Mbps on a 5 GHz 802.11ac connection.
