MSI PRO A520M-A
The MSI PRO A520M‑A is a compact yet robust Micro‑ATX motherboard built on the AMD A520 chipset with an AM4 socket, making it suitable for Ryzen 3000, 4000G, and 5000 series processors and ideal for budget-friendly, mainstream PC builds. It features dual-channel DDR4 memory support across two DIMM slots, accommodating up to 64 GB and capable of reaching speeds up to 4600 MHz with OC support, ensuring smooth multitasking and responsive performance. Expansion options include one PCIe 3.0 x16 slot for graphics cards and a PCIe 3.0 x1 slot for add-ons. Storage needs are addressed with one M.2 slot (supporting PCIe 3.0 x4 or SATA) and four SATA 6 Gb/s ports with RAID 0/1/10 support for ample drive flexibility. Networking is handled by a Realtek Gigabit LAN controller, and audio is delivered through Realtek ALC892 codec with 7.1‑channel support. The rear I/O panel provides HDMI and DVI-D display outputs (requiring a CPU with integrated graphics), four USB 3.2 Gen1 and two USB 2.0 ports, as well as dual PS/2 connectors for legacy devices. Built with a durable 6-layer PCB featuring 2 oz thickened copper, it includes MSI’s Core Boost for stable CPU power delivery, Audio Boost, EZ‑Debug LEDs, double ESD protection, and fan control via BIOS or software. The board also supports Mystic Light RGB header and TPM header, making it a reliable and efficient base for straightforward AM4 systems, though it remains a bare‑bones option due to its minimal features and lack of Wi‑Fi
