Mini-ITX is a small form factor motherboard standard designed for compact and low-power computer systems. Measuring 17 x 17 cm (6.7 x 6.7 inches), Mini-ITX boards are significantly smaller than traditional ATX boards, allowing for more space-efficient builds. Despite their size, they still include essential connections and components like CPU, RAM, and expansion slots, making them suitable for a variety of applications such as home theater PCs and small form-factor gaming PCs.

Key Takeaways

  1. Mini-ITX is a small form factor motherboard, designed for compact and low power consumption computers, such as home theater PCs or small form factor builds.
  2. It measures only 17cm x 17cm (6.7 inches x 6.7 inches), enabling it to fit in tight spaces while still providing essential functionality and compatibility with various hardware components.
  3. Despite its small size, Mini-ITX motherboards can support powerful processors, decent integrated graphics, and multiple peripherals, offering a good balance between space efficiency and performance for various computing needs.


The Mini-ITX term is important in the realm of technology as it signifies a small and versatile motherboard form factor that has greatly impacted the computer industry.

With dimensions of just 17×17 cm (6.7×6.7 inches), Mini-ITX motherboards have enabled the development of compact, efficient, and powerful computer systems.

This smaller footprint fosters innovation in various fields, from creating space-saving computers for home and office use to powering purpose-built devices and Internet of Things (IoT) applications.

Overall, Mini-ITX’s importance lies in its potential to revolutionize the way computer systems are designed and utilized, catering to the growing demands for powerful yet compact computing solutions in today’s technology-driven world.


Mini-ITX is a compact motherboard form factor designed with the primary purpose of reducing the overall size of computer systems while maintaining core functionality. The smaller footprint of Mini-ITX has allowed for innovation and creativity in the development of various devices that require computer technology, such as home automation systems, media centers, and even custom-built gaming consoles.

This form factor has been particularly popular for small form-factor PCs (SFF PCs) which prioritize performance, efficiency, and space-saving capabilities. These devices are used in instances where limited space, portability, or low-power consumption are concerns, such as in confined workstations, embedded systems, or energy-efficient green computing solutions.

Despite its reduced size, Mini-ITX motherboards manage to accommodate essential components such as a CPU, RAM, storage drives, and input/output connections, thereby ensuring that users do not have to sacrifice functionality for a smaller form factor. Additionally, Mini-ITX has proven itself as a versatile option for creating specialized systems – for example, fanless, passively cooled machines for industrial environments, or portable gaming systems with powerful hardware.

As technology has advanced and components have become more efficient, Mini-ITX systems have increasingly been able to rival the performance of their full-sized counterparts, allowing users to meet their computing needs without the burden of a large and cumbersome device.

Examples of Mini-ITX

Mini-ITX is a compact motherboard form factor designed for smaller computer systems, measuring just 17 cm x 17 cm. Here are three real-world examples of Mini-ITX technology:

Home Theatre PCs (HTPCs) – Mini-ITX motherboards are popular choices for building HTPCs due to their small size, which allows for a compact and unobtrusive setup. An HTPC might be used for streaming movies, watching live TV, or playing digital media files on your TV.

Small-Form-Factor (SFF) Gaming PCs – Many gaming enthusiasts have chosen Mini-ITX motherboards to build high-performance PCs with a small footprint. The compact size of Mini-ITX allows users to have powerful gaming rigs that can fit into tiny cases, making it perfect for LAN party setups or when desk space is limited.

Industrial and embedded systems – Mini-ITX motherboards are often used in industrial and embedded computing applications where space is limited. Examples include panel PCs, kiosks, digital signage solutions, and IoT devices. The small form factor enables these applications to have a minimal physical presence while still providing powerful computing capabilities.


What is Mini-ITX?

Mini-ITX is a small form factor motherboard standard that is designed for compact and energy-efficient computer systems. It was introduced by VIA Technologies in 2001 and measures 17cm x 17cm, making it an ideal choice for space-saving builds, such as home theater PCs (HTPCs) and embedded systems.

What are the advantages of using a Mini-ITX motherboard?

There are several advantages to using a Mini-ITX motherboard in your build, including smaller size, lower power consumption, and support for more compact cases. This makes them ideal for situations where space is limited or where a discrete, unobtrusive system is desired.

Are Mini-ITX motherboards compatible with all types of CPUs?

Mini-ITX motherboards come in various designs and configurations, which support different types of CPUs. However, not all Mini-ITX motherboards are compatible with all CPU types, so it is essential to check the specifications of the motherboard and ensure that it supports the desired processor before making a purchase.

How do Mini-ITX motherboards differ from standard ATX motherboards?

Mini-ITX motherboards are smaller in size (17cm x 17cm) compared to the standard ATX motherboards (30.5cm x 24.4cm), resulting in less space for components and expansion slots. While a standard ATX motherboard typically offers multiple PCIe slots, RAM slots, and additional connectivity options, Mini-ITX motherboards generally have a single PCIe slot and two RAM slots, limiting expansion options and making them more suitable for smaller scale builds.

Can I use Mini-ITX motherboards for gaming?

Yes, you can use Mini-ITX motherboards for gaming, provided they support the necessary components like a powerful CPU and a dedicated graphics card. Many high-performance Mini-ITX gaming systems are available on the market, and some gamers prefer Mini-ITX builds for their portability and sleek design. However, due to space constraints, cooling options may be limited compared to larger form factor systems, and users with more demanding gaming requirements may want to consider larger motherboard options like ATX or micro-ATX.
