Form factors for Motherboards

Form factor for motherboards is the description for its general form and size. It is used to avoid the possibility of incompatibilities between different hardware

manufactures. It also defines the type that power supplies are available, the supported casesizes, how the board is laid out and arrangement on the motherboard, as well as the position of the mounting holes. If you are building your personal computer Form factor is crucial in that it specifies the right cases and parts for the PC system. Today, ATX is the most popular form factor used for laptop computers. There are various motherboard form factors and are as follows:

AT & Baby AT: Prior to 1997, a big motherboard was being used in IBM computers. In the following years, as technology advanced the size of the motherboard was reduced, and IBM launched an expanded motherboard that used the AT (Advanced Technologies) format factory. On August 14, 1984, IBM released AT as the AT motherboard form factor, which was in widespread use in the 1980s. The dimensions of AT are 12″ wide and 13.8″ deep. This size is seldom used and was replaced with ATX or Baby AT. Buy a low price laptop ic online in India.

It was in use from 1985 to the late 1990s, along with the 386, 286, 486 as well as Pentium computers. The size of Baby AT is 8.57″ and 13.04″ deep. It is closer than the IBM XT motherboard. It was originally designed to work with peripheral devices, such as the mouse and keyboard.


 It is the acronym as Advanced Technology eXtended the first time it was published by Intel in July 1995. It is a standard that defines the dimensions of the motherboard to enhance standardization. There are several versions of it; 2.01 was released in February 1997, 2.01 was launched in February 1997. Version 2.03 came out in the month of May. In June 2002 the version 2.1 was released as well as 2.2 was launched in February 2004. Up until mid-1996, ATX boards were not more well-liked in the marketplace and they were only introduced replacing Baby-AT boards on new systems. The dimensions that are Standard ATX or Full-ATX are 12″ wide by 9.6″ wide x 9.6″ deep. There are some improvements to the ATX form factor , as well as one 20-pin connector to provide power supply with less overlap between the motherboard and drive bays, and I/O Port connectors, which are soldered directly on the motherboard.


The BTX comes with features like an improved layout to allow for cooling, a slim profiling, support for high mass motherboard components and a board that can be scalable to support a variety of sizes for systems. Intel announced that it would stop development of the BTX in September of 2006. It was designed to provide advantages such as PCI Express, ATA, and USB 2.0.

In addition, it makes use of in-line airflow , which allows you to change the locations of slot expansion and memory. Its primary components including chipsets, graphics controller and processor, utilize the same airflow. This helps reduce the amount of fans needed within the system. That’s the reason why noise that is not needed reduces. The industry regards the ATX design in terms of standard, even though older AT systems are still being used. It is believed that the BTX design is not compatible with the form factor of ATX. This means that it’s not a norm for the market. Check out ssd 120gb price online.

In the field of telecommunications, it refers to discontinuous transmission. It is a technique which is employed to increase the efficacy of two-way wireless voice communications. It works by temporarily changing the channel or power source to a wireless portable phone in which voice input cannot be recognized.

In computers it’s a type of component for motherboards. It is a variant of the ATX specification. AMD came up with the DTX in the month of January 2007. It was developed specifically for computers with small form factors like home theater computers that measure 8 x 9.6 inches. This is an open standard, as declared as such by AMD and has less compatibility with ATX form cases. In addition it is the Mini-DTX version, which was smaller was also created which had 8.0-inches and 6.7-inches dimensions. It is made up of fewer levels of wiring for printed circuit boards, through which it has an affordable manufacturing cost. It was planned to be used as a standard for smaller computers like the Shuttle “SFF” model.


(Low Profile Extension) The most commonly used motherboard design, which was invented in 1987 by Western Digital in 1987. The dimensions of the LPX motherboard measures 9″ across and thirteen” deep. It was first utilized in the latter half of the 1980s and into the 1990s. When compared with other motherboards, it features numerous locations of the serial, video parallel, PS/2 ports. It is referred to as low profile because it has large slots for the riser device that allows the expansion devices to be placed in parallel with the motherboard. The computers with Low profile motherboards appear smaller when compared to an older motherboard computer.


is smaller motherboard created following the ATX form factor and comes with similar advantages. However, it increased the overall design through reducing physical dimensions of the board. The year was 1997 when Intel created the world’s first motherboard mATX. The dimensions of the mATX motherboard are 9.6″ wide by 9.6 ” deep. However, it is able to be reduced as low as 6.75″ wide and 6.75″ wide x 6.75″ deep. Additionally, it can be installed in ATX and smaller cases. It gives you additional I/O space in the rear and, with the aid of integrated Input/Output connectors, it helps reduce emission.

The NLX motherboard,

 which is an X-shaped board that refers to New Low Profile Extended. In the latter part of 1990 the NLX motherboard hit the market. The motherboard was introduced in the month of March, 1997. the NLX motherboard was designed and approved by Intel. The motherboards are able to be removed quickly and easily. It was designed to replace the standard LPX design. The dimensions for this NLX motherboard measures 9″ wide by 13.6″ deep at its maximum, and 8″ 10″ deep at its minimum. It has a range of features like the ability to support AGP, DIMM, USB, Pentium II, larger memory modules, smaller cases, and is able to reduce cable length of cable. It is also an exact normal form factor (unlike NLX form factor) with more options for components to repair and upgrade.

How many slots or ports are there on the motherboard?

There isn’t a method to determine the number of ports available on the motherboard. The best method of determining the ports or slots on the motherboard is to study the specifications in its manual. If you’ve lost the motherboard’s documentation you can download it in PDF format on the website of the manufacturer at no cost.

How do I connect the motherboard with the case of the PC?

The motherboard is connected to the case for desktop computers by using standouts. Once the motherboard is connected to the computer case the other devices are also connected to the expansion card or to the motherboard.

Standouts: Standouts are also referred to as standoffs or spacers that are small metal or plastic screws that join to the computer case in order to support the motherboard as illustrated in the image below.
