Motherboards are called the central circuits of a computer that bind all the parts of the computer together. It distributes all its power across the circuits which then acts like a conduit due to which the innards start working together.
ATX vs Micro ATX
The main difference between ATX And Micro ATX is that ATX is a rectangular board and its size is 305mm by 244mm whereas Micro ATX is a square board and its size is 61mm by 244mm.
The number of expansion ports that are located at the bottom end is more in the ATX format than the Micro ATX format which is one of the downside of the Micro ATX format.
This is a partial offset by most of the board manufacturers integrating the common functions like networking, graphics and sound. It is now common to see computers that no longer use the expansion ports.

What is ATX?
The ATX format was developed in the year 1995. It is an enhanced AT model to ensure a more stable circuit. The ATX board is rectangular in shape and it’s dimensions are 305mm by 244mm.
There have been many noticeable changes or upgrades to the newer models. For example, the ports in the newer models are arranged in such a way that they don’t overlap each other.
Also, the number of drive bays have increased in the new formats. This makes the number of drive bays to be more in the ATX form factor than in the Micro ATX form factor.
What is Micro ATX?
The Micro ATX format was developed in the year 1997. It is backward compatible with the design of the ATX. It is one of the newer formats that were developed after the development of the ATX board.
To deal with this problem of limited expansion slots, many peripherals are integrated. The ATX subsets are the mounting points of Micro ATX format and it uses the I/O panel.
For someone who is looking forward to build a gaming PC, the Micro ATX board will be an excellent choice. It has enough RAM slots and also some free slots to ass any other PCIe expansion cards.
Main Differences Between ATX and Micro ATX
- The number of drive bays in a ATX form factor is more than that of in a Micro ATX form factor.
- A Micro ATX board can be installed in an ATX chassis but the other way is not around is not possible.
Thee most used motherboards are ATX and Micro ATX. The ATX format was developed in 1995 and the Micro ATX format was developed in 1997. They both have different shapes and sizes.
The ATX board comes with five expansion slots whereas the Micro ATX board comes with only three expansion slots. The drive bays in the ATX form factor are more in number when compared to the drive bays in the Micro ATX form factor.
In case of the Micro ATX board, there are only a limited number of slots present and it can be only expanded to a maximum of four slots. Many peripherals are integrated to make up for this limitation.
