What is a defining feature of ITX motherboards?

ITX motherboards are specifically designed with a focus on low power consumption and compact form factors, making them ideal for small form factor PCs, home theater PCs (HTPCs), and other types of systems where space is at a premium and energy efficiency is desired. This low power design is often paired with the need for efficient cooling solutions and can lead to quieter operation, which is particularly advantageous for users who prioritize a silent computing environment.

In contrast, traditional ATX motherboards tend to support more features and larger components, generally consuming more power and generating more heat. The design objectives of ITX boards cater to mobile and embedded systems that benefit from reduced energy use, contributing to their appeal in specific applications that require less power.
