AM4 micro-ATX board for Ryzen systems

The ASUS PRIME A520M-R is a micro-ATX motherboard built around the AMD A520 chipset and AM4 socket. It supports Ryzen 3000, 4000 and 5000 series desktop processors, including G-series APUs. The board provides an HDMI port, a Realtek 1 Gb wired network connection, rear and front USB 5 Gbps ports, SATA 6 Gbps connectors and an M.2 slot.

Suits entry builds, not multi-drive

This board fits builders assembling a compact office or home PC with a single M.2 drive and a few SATA devices. Buyers who need more than one M.2 drive, more than four SATA devices or networking faster than 1 Gb should look at other chipsets.

The A520 chipset defines the feature ceiling

The AMD A520 chipset determines the number of high-speed lanes available for M.2, SATA and USB 5 Gbps ports. It also sets the PCIe generation used by the primary expansion slot. If the required lane count or PCIe generation exceeds what A520 provides, the board will not meet the build requirements.

Questions about this item

What CPU cooler mounting pattern does the AM4 socket on this board require?

The AM4 socket uses the standard AM4 mounting pattern, so any cooler rated for AM4 will fit without an extra bracket.

Can I keep my Ryzen 3000 series processor when moving to this A520 board?

Yes, the board supports Ryzen 3000 series desktop processors in the AM4 socket alongside newer 4000 G-series and 5000 series chips.

How do I confirm the M.2 slot is active after installing a drive?

Enter the BIOS and check the storage configuration page — the M.2 device will appear there when the slot detects the drive.
