Micro ATX Vs Mini ITX: Choose a Right Size for Your Assembly

The form factor of a motherboard is a standard set by manufacturers that sets its general and connection dimensions, i.e. the size of the attachment to the case, the number and location of the interface slots for memory connection with random access, video cards, all kinds of cards expansion, input and output ports, and further essential interface connectors. In this article, I’m going to elaborate Micro ATX Vs Mini ITX:

Is Mini-ITX Better Than ATX?

Mini-ITX motherboards are smaller in both altitude and breadth than micro-ATX motherboards. They typically only have a single PCIe lane. Its advantage, however, is in its smaller size. On the other hand, if you want to go for a larger case, you can probably fit any motherboard in it.


Micro ATX motherboards and computers tend to be the cheapest option. If you’re looking for a PC where you have no interest in upgrading or installing additional hardware, you may be able to save some money by choosing a smaller motherboard.  On the other hand, Mini ITX is smaller but has higher price than MATX.

Why Is Mini ITX So Expensive?

Like the Asus Z97 ITX board is around $200 compared to the ATX which is around $120. Because when things get small enough it starts to take a lot of planning to fit everything into the small space. Therefore, it pushes the price up. Also, many mITX boards come with built-in WIFI, which costs money. Another reason is the demand of MITX is higher due to its small size as it fits in a small space. So, its higher demand leads to rise in price.

Some Common Differences between Micro ATX & Mini-ITX:-

  • Mini-ITX is considerably miniature in size than micro-ATX.
  • Micro-ATX has 3 sizes: normal, larger & smallest, whereas mini-ITX has a permanent regular size.
  • Micro-ATX can also be a substitute for a full-size ATX motherboard, since all components on both motherboards are the same.

Are Mini ITX Builds Worth It?

Building a small form factor machine might mean an extra hour or two of arranging cables in the tight confines of a mini-ITX case, but it’s definitely worth it and saves a lot of space. The forfeits are, for the majority of us, fictional as well, as long as you only need a 1 PCI-E card.

Are Smaller Tables “Slower”?

Regardless of their dimension, you shouldn’t trace those smaller motherboards “perform sluggish” than bigger ones. Of course, going smaller means you can sacrifice PCI-E slots and RAM, which will mean the computer’s potential horsepower is less than its bigger siblings. You may also find that smaller boards don’t handle over-clocking and high-end usage. However, in terms of smaller tables being slower “by nature”, they shouldn’t be.

Final Verdicts:-

The form factor of a computer can be a puzzling matter. Now you know their main differences, how they are used and which one suits you best.
