10 Best Mini Itx Motherboards 2025 in the United States

The ASUS AMD AM4 mini-ITX motherboard (PRIME A320I-K/CSM) is a compact and efficient option for building a small form factor PC. It supports a wide range of AMD Ryzen processors from the 1000 to 5000 series, which gives you flexibility in choosing a CPU. With a chipset type of AMD A320, this motherboard is more suitable for entry-level to mid-range builds, as it may not support overclocking and some advanced features found in higher-end motherboards.

It has a single CPU socket (Socket AM4) and two RAM slots supporting DDR4 memory at speeds up to 3600MHz, with a total capacity of 32GB, which should be sufficient for most users' needs. The inclusion of a 32Gb/s M.2 slot allows for high-speed storage options, and it also has SATA 6Gb/s ports for additional storage drives. Expansion options are somewhat limited with only one PCIe slot, which is typical for mini-ITX form factors.

Connectivity features include HDMI and DisplayPort for video output, multiple USB 3.0 ports for fast data transfer, and an Aura Sync RGB header for those interested in customizable lighting. Power delivery is adequate for most standard tasks but might be insufficient for high-performance or heavily overclocked systems. The BIOS/UEFI interface is user-friendly, making it easier to configure settings and manage the system. One drawback is its dated chipset, which limits some advanced features and future-proofing compared to newer models. Additionally, the limited expansion slots might be a constraint for users looking to upgrade multiple components. This motherboard is a good choice for users looking to build a compact and reliable PC without needing the most advanced features.
