What Is Micro ATX Form Factor?

Micro ATX

After the motherboard’s standard ATX form factor, one of the more recent versions is Micro ATX. Also, the Micro ATX is not different from the standard ATX form factor. You can name Micro ATX the smaller sibling of standard ATX. Chiefly, its launching took place in 1997, and knowingly, it was backward compatible with standard ATX.

To this day, its I/O panel is similar to ATX, and the mounting point of Micro ATX is the subset of ATX. Moreover, the Micro ATX uses the exact chipsets that are like standard ATX. It tells that you can utilize it no matter if they are made for ATX motherboards. There is not much difference between Micro ATX and ATX in general.

Despite all these similarities between the two, the Micro ATX expansion slots are insufficient. Further, the standard ATX has seven expansion slots for PCI Express. On the other hand, the expansion slots in Micro ATX for PCI Express are only four.

Are you planning to build your personal computer, then the mATX mobo is an affordable option. But always keep in mind that the opportunity for expansion is limited.

There are two slots for graphical processing units and four slots for memory set up in the latest versions of motherboards. So, there is no more requirement for additional expansion slots, unlike ATX.

Besides, ATX vs mATX is another comparison that people make these days.

An excellent choice for gamers
Big enough to fit most situations
Affordable in most cases
Four slots for PCIe

Cons

Only for a single GUI step up

This Mini ITX size can support only two memory slots means it can hold up to 32 Gb with two 16 Gb cards. But this isn’t the downfall of the Micro ITX motherboard, as 32 Gb memory is more than enough for a gamer while not making the system bulky. You can handle a lot of heavy computing tasks and get peak performance with this memory setup.

Further, with all these great features it has some drawbacks as well. With this compact design, its PCIe slots are at the corner. Therefore, it is challenging to fit GUI in some cases, which is its negative aspect.

Pros

Ideal for standard PC use
Best for portable PC built
Lightweight

Cons

Adding graphics card is challenging
PCIe slots are at the corner
