Difference between ATX and BTX

In the world of computer components, there are two major motherboard types: ATX and BTX. While they may look similar, these two formats have a few key differences. In this blog post, we’ll take a look at what sets ATX and BTX apart, and which one might be right for you.

What is ATX?

ATX is a motherboard form factor developed by Intel in 1995. It was the first major change to the motherboard design since the AT form factor was introduced in 1984. The ATX specification includes dimensions for the board, I/O connector locations, power connector locations, and mounting points. ATX motherboards are typically wider than AT boards, which allows for a better layout and more space for components. ATX boards also have an extra row of pins for the power connectors, which helps to improve airflow and cooling. In addition, ATX motherboards typically include additional features such as on-board sound and video, as well as extra USB and SATA ports. Today, ATX is the most common motherboard form factor and is used in everything from desktop computers to servers.

What is BTX?

BTX is a motherboard form factor developed by Intel. BTX motherboards are designed to provide improved thermal management and increased system reliability. BTX boards are available in three different sizes: full-size BTX, micro BTX, and pico BTX. BTX motherboards typically use less power than comparable ATX boards and generate less heat. BTX boards also have fewer exposed connectors, which helps to reduce electromagnetic interference. BTX boards are not compatible with older ATX cases, power supplies, or coolers. For more information on BTX motherboards, please consult your computer’s manufacturer or an authorized dealer.

Difference between ATX and BTX

ATX and BTX are two different form factors for computer motherboards. ATX is the most common form factor, and is typically used in desktop computers. BTX is a newer form factor that is designed to improve airflow and cooling. As a result, BTX motherboards are typically used in high-end gaming computers or servers where heat dissipation is a concern. ATX motherboards are typically wider than BTX motherboards, and have more mounting holes for expansion cards. BTX motherboards typically have more integrated features, such as sound and video cards. However, both ATX and BTX motherboards can be used in either desktop or tower cases.


The two types of connectors, ATX and BTX, have different purposes. ATX connectors are mainly used in desktop computers while BTX is mainly used in laptops. If you’re not sure which type of connector your device uses, consult the owner’s manual or contact the manufacturer.
