Difference Between ITX and ATX


Both mini-ITX and micro-ATX are small form factor motherboards that are used in small computers. As a motherboard, both ATX and ITX provide the basic features that can run a computer.

Small form factor motherboards is the common term for any motherboard below a certain size. Most of these motherboards are used in computer devices which are smaller than a laptop. Non-standard computers and computing devices (like small or handheld computers) are often the primary locations of these motherboards. The popular tablet also uses these types of motherboards.

Aside from the usual computer applications, these motherboards are used within appliances like home theater systems, digital cable boxes, smart phones, handheld media players, and digital video recorders.
Smaller motherboards like the micro-ATX and mini-ITX are often preferred because they are more affordable, simpler, easier to manage, and easier to assemble. Of course, the major disadvantage of any small form factor motherboard is that it sometimes does not perform as effectively as a normal-sized motherboard. There are fewer electrical layouts and fewer computer components that can be attached to this kind of motherboard.

Both micro-ATX and mini-ITX are popular among people who want to customize their own motherboards and, in a sense, their own computers. These two motherboards are the most common small form factor motherboards on the market.

The mini-ITX has the standard and fixed size of 170 mm. x 170 mm. (6.7 inches by 6.7 inches). It is a low-power, small form factor motherboard developed by VIA Technologies and released in November, 2001. Today, Intel and AMD are also manufacturing this kind of motherboard.

This motherboard is designed to support low-cost computers in small spaces like cars, set-up boxes, and network devices. It is also used in thin client computers and case designs for ATX, micro-ATX, and other ATX variants.

Mini-ITX is very advantageous due to its small size, low noise, and less power maintenance.

By contrast, the micro-ATX was introduced in 1997. In comparison with the mini-ITX, this motherboard is bigger in terms of specifications. This motherboard has three sizes: standard (305 mm. x 244 mm. or 12 inches x 9.6 inches), minimum (171.45 mm. x 171.45 mm. or 6.9 inches x 6.9 inches), and the maximum (244 mm. x 244 mm. or 9.6 inches x 9.6 inches). The standard size is 255 mm. more than the minimum size.

This motherboard can also support CPUs (Central Processing Units) from VIA, Intel, or AMD. It has four PCI or PCI Express expansion slots. And, unlike the mini-ITX, has a full range of integrated peripherals like audio, graphics, and Ethernet.

The micro-ATX is also backward compatible with the ATX motherboard. It can also be used in full-size ATX cases with the same power connections and same chipsets in full ATX boards.

Due to its compatibility, the micro-ATX is considered more mainstream compared to the mini-ITX.


1.The mini-ITX is significantly smaller compared to the micro-ATX.
2.The micro-ATX has three sizes: standard, maximum, and minimum while the mini-ITX has a standard and fixed size.
3.The micro-ATX can also be a substitute for a full-size ATX motherboard since it has all the components of both motherboards the same.
4.Due to its size, the mini-ITX can only hold a number of features and components while the micro-ATX comes fully furnished with audio, graphics, BIOS, processor, memory, storage, clock generator, expansion cards, power connectors, and other motherboard components. It is the opposite for the micro-ATX since it can hold more components and can still function as a full motherboard.
5.The mini-ITX does not require specialist components unlike the micro-ATX.
