Mini-ITX or microATX?

If you’re here you want a diminutive platform as the base for a new system. MicroATX is an option offering many of the benefits of a full ATX size board but in a smaller form. Meanwhile, Mini-ITX has more of a focus on size as the primary focus, with basic usefulness rather than fuller feature sets taken into account. MicroATX motherboards are 244 × 244 mm (9.6 × 9.6 inches), while mini-ITX motherboards are 170 mm × 170 mm (6.7 × 6.7 inches).

What is the disadvantage of a mini-ITX motherboard?

Mini-ITX motherboards, while compact and space-efficient, often come with limitations in expansion capabilities. They typically offer fewer PCIe slots, RAM slots, and storage options compared to larger motherboards. This can restrict upgrade potential and may not cater to users with high-end or multiple-component requirements. Additionally, their smaller size can sometimes lead to higher temperatures due to denser component packing, which might necessitate better cooling solutions.

Do Mini-ITX motherboards use less power?

Mini-ITX motherboards are generally designed to be power-efficient, consuming less power compared to larger motherboards. This efficiency is partly due to fewer onboard components and the need to fit into smaller, often more power-conscious, builds. However, the actual power consumption depends on the specific components and the overall system configuration.
