AM4 Mini-ITX board for Ryzen 3000/4000 builds
The ASRock A520M-ITX/AC fits the AM4 socket and targets compact systems using 3rd-gen Ryzen 3000 or 4000 series CPUs. It excludes the Ryzen 5 3400G and Ryzen 3 3200G. The A520 chipset provides a compact foundation with integrated 802.11ac Wi-Fi and Bluetooth on the rear I/O.
Verify CPU cooler clearance
The board carries two 288-pin DDR4 slots supporting dual-channel up to 64 GB. Matisse CPUs run DDR4 at speeds from 2133 to 4600+(OC); Renoir APUs reach 4733+(OC). Check your cooler dimensions against the socket keep-out zone and ensure DIMM height clears the cooler in a Mini-ITX chassis.
VRM and chipset thermals stay stable in a tight case
The single PCIe 3.0 x16 slot and one Ultra M.2 2280 socket (PCIe Gen3 x4 or SATA) share the A520 chipset thermal budget. Under sustained load the compact VRM and passive chipset heatsink rely on case airflow. Four SATA3 6.0 Gb/s ports with RAID 0/1/10 and a Realtek 1 Gbps LAN complete the I/O.

Questions sur cet article
What comes in the box with the ASRock A520M-ITX/AC and what must I buy separately?
The board includes a pre-installed Intel 802.11ac WiFi module in the vertical M.2 Key E socket. You must buy a compatible AM4 Ryzen 3000 or 4000 series CPU, DDR4 memory, storage and a power supply separately.
Which memory speed should I choose for the A520M-ITX/AC with a Ryzen 3000 CPU?
Ryzen 3000 Matisse CPUs support DDR4 up to 4600+(OC) with official JEDEC speeds at 3200, 2933, 2667, 2400 and 2133 MHz. Pick a kit on the ASRock memory support list that matches your CPU and desired overclock headroom.
What does the 32Gb/s Ultra M.2 rating mean for real SSD performance?
The Ultra M.2 slot runs at PCIe 3.0 x4, giving a theoretical 32Gb/s ceiling. An NVMe drive will hit its rated sequential speeds up to that limit; SATA M.2 drives are capped at 6.0Gb/s instead.
