When it comes to building or upgrading a computer, one of the most critical components is the motherboard. It serves as the main circuit board, connecting all the hardware components together and allowing them to communicate with each other. However, with so many different types of motherboards available, it can be overwhelming to navigate the various form factors, features, and specifications. One term that is commonly seen on motherboards is “ATX.” But what does ATX mean on a motherboard, and how does it impact your computer-building experience?
What is ATX?
ATX stands for Advanced Technology eXtended. It is a specification for motherboards that was introduced by Intel in 1995. The ATX form factor was designed to replace the older AT (Advanced Technology) form factor, which was used in many of the first IBM-compatible computers. The ATX specification defines the physical dimensions, mounting holes, and connector placement for motherboards.
Key Features of ATX Motherboards
ATX motherboards have several key features that distinguish them from other form factors. Some of the most notable features include:
- Size: ATX motherboards measure 305mm x 244mm (12 inches x 9.6 inches) in size, making them larger than many other form factors.
- Mounting Holes: ATX motherboards have a specific pattern of mounting holes that allow them to be secured to the case using screws.
- Connector Placement: ATX motherboards have a standardized placement for connectors such as the power supply, CPU, and memory.
- Expansion Slots: ATX motherboards typically have a combination of PCI, PCI Express, and AGP expansion slots, allowing users to add graphics cards, sound cards, and other peripherals.
Benefits of ATX Motherboards
ATX motherboards offer several benefits that make them a popular choice among computer builders. Some of the most significant advantages include:
- Flexibility: ATX motherboards offer a wide range of expansion options, making it easy to add new hardware components as needed.
- Upgradability: ATX motherboards are designed to be easily upgradable, with features like socketed CPUs and removable memory modules.
- Compatibility: ATX motherboards are widely supported by hardware manufacturers, making it easy to find compatible components.
Common Applications for ATX Motherboards
ATX motherboards are commonly used in a variety of applications, including:
- Gaming PCs: ATX motherboards offer the flexibility and upgradability that gamers need to stay ahead of the curve.
- Workstations: ATX motherboards provide the reliability and expandability that professionals need to get the job done.
- Home Servers: ATX motherboards offer the features and connectivity options that home server builders need to create a robust and reliable server.
Other Form Factors: A Comparison
While ATX is one of the most popular motherboard form factors, there are several other options available. Some of the most common form factors include:
- Micro-ATX: Micro-ATX motherboards are smaller than ATX motherboards, measuring 244mm x 244mm (9.6 inches x 9.6 inches) in size. They offer many of the same features as ATX motherboards but are more compact.
- Mini-ITX: Mini-ITX motherboards are even smaller than micro-ATX motherboards, measuring 170mm x 170mm (6.7 inches x 6.7 inches) in size. They are often used in small form factor PCs and embedded systems.
- Extended ATX (E-ATX): E-ATX motherboards are larger than ATX motherboards, measuring 305mm x 330mm (12 inches x 13 inches) in size. They offer additional features and expansion options, making them popular among enthusiasts and overclockers.
Choosing the Right Form Factor
When choosing a motherboard, it’s essential to consider the form factor and how it will impact your build. Here are a few things to keep in mind:
- Case Compatibility: Make sure the motherboard is compatible with your case. ATX motherboards require an ATX case, while micro-ATX and mini-ITX motherboards require smaller cases.
- Expansion Options: Consider the expansion options you need. If you plan to add multiple graphics cards or other peripherals, an ATX or E-ATX motherboard may be a better choice.
- Space Constraints: If you’re building a small form factor PC, a micro-ATX or mini-ITX motherboard may be a better choice.
Conclusion
In conclusion, ATX is a widely used motherboard form factor that offers flexibility, upgradability, and compatibility. While there are other form factors available, ATX remains a popular choice among computer builders. By understanding what ATX means on a motherboard and how it impacts your build, you can make informed decisions and create a powerful and reliable computer system.
| Motherboard Form Factor | Size (mm) | Size (inches) | Description |

| E-ATX | 305 x 330 | 12 x 13 | A larger version of the ATX form factor, offering additional features and expansion options. |
By considering the different motherboard form factors and their features, you can choose the right motherboard for your needs and create a powerful and reliable computer system.
What does ATX stand for?
ATX stands for Advanced Technology eXtended. It is a specification for motherboards that was introduced by Intel in 1995. The ATX specification defines the physical dimensions, mounting holes, and connector placement for motherboards.
The ATX specification was designed to replace the older AT (Advanced Technology) specification, which was used in many older computers. The ATX specification has undergone several revisions over the years, with the most recent revision being ATX 2.2. The ATX specification is widely used in the computer industry and is supported by most major motherboard manufacturers.
What are the key features of an ATX motherboard?
An ATX motherboard is a type of motherboard that conforms to the ATX specification. The key features of an ATX motherboard include a rectangular shape with a maximum size of 305mm x 244mm, a mounting hole pattern that allows for easy installation in a standard ATX case, and a set of connectors that provide connectivity for peripherals such as keyboards, mice, and monitors.
ATX motherboards also typically include a range of features such as USB ports, SATA ports, and PCIe slots, which provide connectivity for storage devices, graphics cards, and other peripherals. Additionally, ATX motherboards often include built-in audio and networking capabilities, as well as support for overclocking and other advanced features.
