Different Types of Motherboard Form Factors With Definition


The Computer Motherboard comes in lots of variety they differ in size, shape, dimensions, compatibility to hold CPUs, and power supply.

The manufacturer thus produces motherboards that have some common features like their shape, size, and dimensions.

ATX Motherboard Form Factor has dominated the PC Hardware world for a long time.

Therefore Computer motherboard Form Factor can be defined as the basic standard for manufacturing various components of a computer system that are easily fitted in computer cases with a power supply.

For Example:: ATX Motherboard cannot be fitted in an AT Computer cabinet or PC Case | Chassis as Their dimensions and shape differ.

While installing the motherboard in computer cases you have to firstly match The holes which are pre-drilled in the computer case, if they match you can easily Install MB and power supply (SMPS).

Therefore Buying new computer hardware you must take care of the Motherboard form factor.

As Mainboard, power supply, and CPUs are purchased in a package because of their size, shape, dimensions, And compatibility issues.

  • XT,LPX,BTX ,Pico BTX and Mini ITX MB

AT Motherboards::

AT (Advanced Technology) Motherboards are old-style .which has an AT Form Factor. These motherboards were manufactured by IBM in the ’80s these MB dominated the PC Hardware world for a long time.

Baby AT Motherboards::

Baby AT (Advance Technology) MB has both features of XT and AT Form Factors.

These Motherboards have PGA Processor Sockets, SD Ram And DDR Ram Slots, Expansion slots (PCI and ISA Slots) both 12 pin and 20 pins power connectors with Big keyboards ports called DIN and Serial mouse port.

Full ATX::

ATX Stands for Advanced Technology extended they have the features of the ATX Form factor. These mainboards have MPGA CPU sockets, DIMM slots for RAM, Expansion slots (PCI, ISA, AGP)

SATA and IDE connector with ports and connectors 12 pins and 20 pin power connector are available in these types of motherboards.

Micro ATX::

As computer Technology developed the computer market changed and the demand for small and powerful mainboards was huge in numbers.

They were developed using the same ATX form Factor in mind as the price of this motherboard was low the demand Increased rapidly.

Flex-ATX::

This type is not as popular as other ATX Form Factor motherboards.

They are considered to be the smallest in the ATX Family.

They were developed in small size and were low in cost. Flex ATX is a variant of micro ATX motherboard and was developed by Intel in the year 1999 -2000.

Types of Computer Cases

Computer Cases comes in different size, shape, and color with cool features. The computer cases are called chassis.

There are three major types of computer cases ::

  • Desktop Cases
  • Tower Cases
  • Notebook Cases

The Desktop Cases::

The first personal computer used desktop case| chassis the desktop case used to sit flat on the desk and the monitor was used to be placed on it.

The power supply was attached to the backside of the case, cd and DVD RW were installed on the front side of the computer case.

This Computer case was very small in size but the use of this case has not been used recently as the smaller cases have been developed which are more space-efficient.

Tower Cases::

Tower cases are upright on the desk and can be 2 to 3 feet high .there is more space for another computer component to be inserted. These cases are more used in Personal Computers as it can be upgraded easily


The variations in tower cases are as follows::
Midsize towers also called mid-towers, are the most versatile and most popular. They are midrange in size and generally have around six expansion slots.

They are used for ATX, Micro ATX, Extended ATX, Mini-ATX, and BTX systems. The mini tower also called a micro tower, is the smallest type of tower case. They are popular for Micro ATX and Flex ATX.

Notebook Cases::

Notebook cases are used for portable computers they are similar to desktop computers. The notebook cases are small in size therefore it is very difficult for up-gradation.

The very small notebook cases are called as netbooks or sub notebooks.
