Asus Prime A520m-R Motherboard - DDR4, HDMI, M.2, ATX

ASUS Prime A520M-R Motherboard brings reliable micro ATX performance to desktop builds with support for AMD Socket AM4 processors including Ryzen 3000 and 5000 series.

This Prime A520M-R supports DDR4 memory across two DIMM slots in dual‑channel configuration, with ECC compatibility and a wide range of supported memory speeds up to 5100 MHz, allowing flexible memory upgrades up to 64 GB of unbuffered RAM for both productivity and light‑gaming systems.

Storage options are versatile: the board includes one M.2 slot plus four SATA III connectors, supporting up to five drives and RAID levels 0, 1 and 10 for redundancy or performance. Included SATA cables simplify installation and the single PCIe x16 (Gen3) and PCIe x1 slot let you add a discrete GPU and expansion cards.

Connectivity covers everyday needs with HDMI 2.1 for crisp video output, Gigabit Ethernet (RJ‑45), four USB 3.2 Gen 1 Type‑A ports, two USB 2.0 ports and legacy PS/2 ports. Onboard audio delivers 7.1‑channel sound and front panel headers include audio, USB and fan connectors, plus a TPM header for enhanced security.

The micro ATX form factor (236 x 193 mm) and passive cooling design make the Prime A520M-R a compact, quiet foundation for home office PCs, media centers or budget gaming rigs. It uses a standard 24‑pin ATX power connector and supports Windows 10 and Windows 11, ensuring broad compatibility.

Typical use cases include building an affordable productivity workstation with RAID storage for data safety, a compact gaming PC with a discrete GPU, or a home theater PC that benefits from HDMI 2.1 and 7.1 audio. The board’s single M.2 slot enables fast NVMe boot drives while multiple SATA ports serve bulk storage.

Key selling points are clear: AMD Socket AM4 support for Ryzen 3000/5000 CPUs, DDR4 up to 5100 MHz with ECC support, M.2 + SATA storage with RAID, HDMI 2.1 output and a compact micro ATX footprint. The Prime A520M‑R balances functionality, quiet passive cooling and value for mainstream system builders.
