Our take on the ASUS PRIME A520M-K AM4 AMD A520 Micro ATX AMD Motherboard

The ASUS Prime A520M-K is a budget micro-ATX board for AMD's AM4 socket, built on the A520 chipset. It covers the basics: two DDR4 slots, one PCIe 3.0 x16 slot for a graphics card, four SATA III ports and an M.2 slot for an NVMe drive. It has no CPU overclocking support, no PCIe 4.0 and only two memory slots, so it suits a low-cost Ryzen build rather than a tuner's rig. Against B550 boards it gives up overclocking and PCIe 4.0 but costs less and is simpler to set up.

Questions and answers

Does the ASUS Prime A520M-K support Ryzen 5000 CPUs?
Yes, with a current BIOS it runs Ryzen 5000 series chips on AM4. Older stock may need a BIOS update first, so check the board revision or ask the seller.
Can I overclock the CPU on this board?
No. The A520 chipset does not support CPU overclocking, and memory overclocking is limited. Choose a B550 or X570 board if you want to tune.
How many memory slots does it have?
Two DDR4 DIMM slots, so you can run dual-channel with two sticks. Plan capacity up front, since there is no room to add two more later.
Does it have an M.2 slot for an NVMe SSD?
Yes, one M.2 slot runs at PCIe 3.0 speeds, alongside four SATA III ports for 2.5-inch and 3.5-inch drives.
What is the difference from a B550 board?
B550 adds PCIe 4.0 for the graphics card and one M.2 slot, plus CPU overclocking and usually more USB and fan headers. The A520M-K is the simpler, cheaper option.
What comes in the box?
The board, a SATA cable, the I/O shield and a quick-start guide. A CPU, memory and cooler are not included.
Where is the ASUS PRIME A520M-K AM4 AMD A520 Micro ATX AMD Motherboard cheapest?
At Newegg, for $117.95, as of our latest check.
