Difference between AT and ATX

There are many different types of computer motherboards on the market today. While they all share some similarities, there are also key differences between them that can impact your computing experience. In this post, we will take a look at two of the most common motherboard types – AT and ATX – and discuss the benefits of each.

What is AT?

AT is a motherboard form factor that was introduced in 1984. It was the successor to the Baby AT form factor and was itself succeeded by the Extended ATX form factor in 1995. AT stands for Advanced Technology and was originally developed by IBM. The motherboard size is 12 inches by 13 inches. A full-size ATX motherboard is sometimes referred to as a Standard ATX motherboard. The term Full AT is also used, though it is less common. The main difference between Baby AT and AT is that with an AT motherboard, the keyboard and mouse ports are on the front of the case instead of the back. This made it easier to access these ports when the computer was on a desk, as opposed to under the desk like with a Baby AT motherboard. Society, over time, has gotten used to having these ports on the front of the case and now most cases have these ports on the front. If you were to buy a new motherboard today, it would most likely be an ATX motherboard, which is the successor to the AT motherboard.

What is ATX?

A motherboard is a key component of any computer, and the ATX standard is one of the most popular motherboard formats in use today. ATX motherboards are wider than other motherboard formats, typically measuring 12 inches by 9.6 inches. This extra space allows for more connectors and expansion slots, giving users more flexibility when it comes to building their systems. In addition, ATX motherboards typically feature a higher quality componentry than other motherboard formats, making them a good choice for gamers and power users who demand the best performance from their computers. Whether you’re looking to build a high-end gaming rig or a simple office PC, an ATX motherboard is a great foundation for your system.

Difference between AT and ATX

The major differences between AT and ATX motherboards are in their size, power consumption, and features. AT motherboards were the standard for many years, but they are now largely obsolete. ATX motherboards are smaller and use less power, making them more popular in today’s market. They also offer more features than AT boards, including support for newer technologies. As a result, ATX motherboards are generally the better choice for new builds. However, if you’re looking to upgrade an older system, an AT motherboard may be your only option.


Now that we’ve looked at the differences between AT and ATX power supplies, which one is right for you? If you need a high-powered supply for a gaming PC or other demanding application, then an ATX unit is your best bet. However, if you don’t need as much wattage and are looking for a more affordable option, an AT power supply will do the trick. Keep in mind that there are some exceptions to this rule; always consult your computer’s manual to be sure.
