What is the most common motherboard form factor?
ATX
The most common motherboard form factor is ATX. The different types of ATX are known as micro-ATX (sometimes shown as µATX, mini-ATX, FlexATX, EATX, WATX, nano-ATX, pico-ATX, and mobileATX). A smaller form factor is ITX, which comes in mini-ITX, nano-ITX, and pico-ITX sizes.
What factors are used to determine an ATX motherboard?

Motherboard form factors are easily identified by their physical dimensions. An ATX motherboard size is 12 inches by 9.6 inches. An Extended ATX (EATX) measures 12 inches by 13 inches. A micro-ATX (mATX) motherboard measures 9.6 by 9.6 inches.
What is meant by at ATX NLX form factor?
NLX is a form factor from Intel for PC motherboards. Cases and motherboards based on this design first started appearing in 1998. A major difference between NLX and other form factors is that expansion boards are parallel to the motherboard, rather than perpendicular to it as in other form factors such as AT and ATX.
What is meant by at ATX NLX form factors?
What are the 3 sizes of motherboards?
Smaller boards = fewer slots and features. Motherboards come in three main sizes, from largest to smallest: ATX, Micro-ATX and Mini-ITX (Yes, Mini is smaller than Micro).

Can ATX fit in Eatx?
ATX board will certainly fit in eATX motherboard tray. The tray has many form factors for the standoff to screw on.
What is the computers form factor?
Form factor for computers refers to the size, shape, and physical specifications of hardware or hardware components. Computer form factor is used to describe any physical aspect of a computer system. Form factor is very important for connection compatibility.
What are the 4 types of motherboard?
Below are the six different types of Motherboards:
- AT Motherboard. These motherboards have bigger physical dimensions of hundreds of millimeters and hence they are not the right fit for the mini desktop category of computers.
- ATX Motherboard.
- LPX Motherboard.
- BTX Motherboard.
- Pico BTX motherboard.
- Mini ITX motherboard.
What is mATX form factor?
What is M-ATX? M-ATX is the slightly smaller cousin of ATX, cutting its length by around 25 percent, to a typical size of 244 x 244 mm. It supports all of the same processors and graphics cards as ATX motherboards, as well as four RAM slots, but typically cuts back on a few additional features to help save space.
What is ITX form factor?
The Mobile-ITX motherboard form factor measures 7.2 cm x 10 cm (2.8″ x 3.9″) and has no computer ports unless an I/O carrier board is used.
Can a Micro-ATX fit in a ATX case?
microATX was explicitly designed to be backward compatible with ATX. The mounting points of microATX motherboards are a subset of those used on full-size ATX boards, and the I/O panel is identical. Thus, microATX motherboards can be used in full-size ATX cases.
Which is better e ATX or ATX?
In terms of functionality, EATX performs better than ATX, how? Because EATX comes in a larger size, this means you get additional ports and slots for components. In an ATX board, you will usually find 3-4 PCI-e x 16 ports and 4 RAM slots, whereas in an EATX board, you will find 4-8 PCI-e x 16 ports and 6-8 RAM slots.
What’s the biggest motherboard size?
12 inches by 9.6 inches
The largest of the three motherboard sizes we’re looking at, the ATX measures 12 inches by 9.6 inches. The specification requires all ATX motherboards to be this size. It also specifies the locations of the mount points, the I/O panel, the power connectors, and all other various connection interfaces.
What is XT form factor?
The XT (an abbreviation for eXtended Technology) was the first form factor introduced in 1983 by the then popular IBM Personal Computer XT, or simply IBM XT. The IBM XT was intended for business users and can cost up $3,000 USD and more at the time, or about $7,800+ USD in 2019 after factoring in inflation.
What is meant by AT ATX NLX form factors?
How many main types of motherboard form factors are there?
Based on these factors, there are five different types of motherboards, including ATX, LPS, BTX, mini ITX, and AT motherboards. Among which ATX model is the most efficient because of its size, versatility, and rapid cooling abilities. Therefore, they are highly recommended for standard or large computers.
