AM4 socket with A520 chipset

This ASUS PRIME A520M-K motherboard fits AMD Ryzen 5000 series, 5000G series, 4000G series and 3000G series desktop processors. The Micro ATX board measures 22.6 by 22.1 centimetres and supports DDR4 memory up to 64GB across two slots. It provides one PCIe 3.0 x16 slot and two PCIe 3.0 x1 slots for expansion cards.

Entry builds and basic upgrades

The board suits budget office PCs, home servers or simple gaming rigs that do not need overclocking or multi-GPU setups. Builders who want CPU overclocking, PCIe 4.0 lanes or more than one M.2 drive should choose a different chipset. The Realtek ALC887 audio and RTL8111H LAN cover everyday sound and wired networking needs.

Two DDR4 slots capped at 64GB

Maximum memory capacity is 64GB using two DDR4 DIMM slots with supported speeds from 2133 up to 4600 MHz when overclocked. If your build requires four memory slots or more than 64GB total RAM this board will not fit the requirement.

Questions about this item

What case clearance does the 22.6 by 22.1 cm Micro ATX board need?

The board fits any chassis that accepts a 22.6 by 22.1 cm Micro ATX footprint and has matching standoff holes.

Which headers must be connected during installation and which step is often missed?

Connect the 24 pin ATX power, 4 pin CPU power, front panel switches, front USB 3.2 Gen 1 and USB 2.0 headers, SATA cables and the I/O shield; the front panel header pinout is the step most often wired incorrectly.

What maintenance will the onboard battery require and how is it accessed?

The onboard battery maintains BIOS settings; when the system loses time or settings after power off, power down, unplug, remove the old cell from its holder and fit a new one of the same type.
