Motherboard mini itx

The mini ITX motherboard measures 17x17 cm and is the smallest standard form factor for computers, ideal for compact PCs and embedded systems.

About this subject

The mini ITX is a motherboard form factor introduced by VIA Technologies in 2001, with exact dimensions of 17 by 17 centimeters. It was designed for low-power, compact computers such as home theater PCs (HTPCs), home servers, and portable gaming rigs. Despite its small size, it supports modern processors, RAM, and in many models, a dedicated graphics card.

Unlike ATX or micro ATX boards, mini ITX features only one expansion slot, usually PCIe x16, and two RAM slots. This limits upgradability but favors efficient and quiet builds. Many enthusiasts choose cases under 10 liters, using low-profile coolers and SFX power supplies.

The popularity of this form factor increased with the evolution of integrated processors, such as the Ryzen G series and Intel with Iris graphics, which eliminate the need for a dedicated GPU in daily tasks. Additionally, mini ITX is widely used in industrial embedded systems and edge computing servers, where space and power consumption are critical.

Fun fact: the name stands for 'Information Technology eXtended,' following the VIA EPIA lineup. Today, manufacturers like ASUS, Gigabyte, and ASRock offer models with built-in Wi-Fi, USB-C ports, and overclocking support, proving that small size does not sacrifice performance.
