Hardware standardization is one of the biggest strengths of desktops. Users can combine as well as choose compatible parts as they wish. However not every motherboard has the identical bodily dimension. Motherboards have diverse form factors for various sorts of computers. Today in this article we are going to compare ATX Vs MATX Vs ITX, so user can easily pick one according to their needs

Different Standards:-

Just like other computer components, motherboards have standard form factors, including ATX, Micro ATX and Mini-ITX. Almost any home computer motherboard at your local computer store or online will have one of these flavors.

A large number of cases support the three main sizes of motherboards. The mounting points are drilled to the appropriate points, and the appropriate place is available for the rear ports and the accompanying I / O shield that cover them.

This is a nice thing, but to decide which motherboard is right for you, you need to consider things like space, and your experience in building PCs and performance needs.

Computer Motherboards: The Basics

Intel formed the ATX and earliest launched it in 1995. For almost 25 years, the ATX design was the form factor that dominated home and office computers. The largest of the three motherboard sizes we look at, the ATX measures 12 inches by 9.6 inches. It also indicates the locations of the mounting points, I / O board, the power connectors and all the other various connection interfaces.

All of these features are critical to any motherboard. Mounting points keep the motherboard away from the metal surface of the chassis to prevent power pants. I / O board and accompanying protector allow you to access the back ports of your computer for views, audio and USB. Next, you have the power connectors and all the other interface points that must be in the expected locations to assist system builders.


Not everybody wishes for an ATX-sized motherboard – particularly if the target is to build somewhat more solid. Enter, Micro ATX boards, measuring 9.6 inches by only 9.6 inches. Similar to ATX’s large motherboards, the standard sets out all the different critical points.

Finally, the Mini-ITX, developed by Via Technologies in 2001, is the smallest of them all, measuring just 6.7 inches by only 6.7 inches.


ATX motherboards can be greatly expanded. They usually have six PCIe slots (or less) for things like graphics, sound and network cards. However, there are extended ATX (or EATX) boards that include seven PCIe slots, but these are aimed at amateurs and servers and are outside the scope of this article.

Micro ATX can hold up to four PCIe slots, while Mini-ITX has only one graphics card.


RAM is also limited in Mini-ITX. It has room for only two slots compared to four on ATX or Micro ATX boards. This is not to say that Mini-ITX extensions cannot have a healthy amount of RAM. For example, if you want 32 GB of RAM, you just put two, 16 GB, on it, while in the other two motherboards you fill 8 modules.
