Difference Between ITX and ATX

By: | Updated: Sep-19, 2021

Chances are, you have never heard of the term ITX or ATX. These are the two main motherboard form factors used in the PC industry.

ITX is a smaller form factor than ATX, and it is mainly used for motherboards that have a mini-ITX form factor. This means that they are designed to fit into an ITX case, which is typically smaller than an ATX case. The size of the motherboard also determines how much space you will have inside your case.

If you are a hardcore gamer, you will want to get a motherboard that is designed for an ITX case. The smaller size of the motherboard means that you will have more space inside your case, and it also means that you can install a larger graphics card in your system.

ATX is the most common form factor used in PC cases today. It is bigger than ITX, but it still fits into an ATX case. The size of the motherboard determines how much space you will have inside your case, and this is why ATX is the most popular form factor.

If you are looking for a motherboard that will fit into an ATX case, then you should get one that has a micro-ATX form factor. This means that it will have a smaller size than an ATX motherboard, but it will still fit into an ATX case. The size of the motherboard also determines how much space you will have inside your case.
