When building a custom PC, choosing the right motherboard is crucial. Two of the most common motherboard form factors are ATX and EATX. While both are suitable for most builds, there are key differences between them that can impact your hardware choices and overall system performance. In this comprehensive guide, we’ll delve into the details of ATX vs EATX mainboards, helping you make an informed decision for your next build.
ATX Mainboards: A Versatile Standard
ATX (Advanced Technology Extended) is the most widely used motherboard form factor, known for its versatility and compatibility. ATX motherboards measure 12 inches by 9.6 inches, providing ample space for various components. They typically feature 7 to 10 expansion slots, including PCIe x16, PCIe x1, and PCI slots, allowing you to connect multiple graphics cards, sound cards, and other peripherals. ATX motherboards also offer a wide range of connectivity options, including USB ports, SATA ports, and M.2 slots for fast storage devices.
EATX Mainboards: For Maximum Expansion and Performance
EATX (Extended ATX) is a larger motherboard form factor designed for high-end systems and workstations that require maximum expansion and performance. EATX motherboards measure 13.6 inches by 13 inches, providing significantly more space than ATX counterparts. They typically offer 12 or more expansion slots, including multiple PCIe x16 slots for multi-GPU configurations. EATX motherboards also feature enhanced cooling options, such as larger heatsinks and additional fan headers, to support high-performance components.
Key Differences between ATX and EATX Mainboards
Size and Dimensions
The primary difference between ATX and EATX mainboards lies in their physical dimensions. EATX motherboards are larger than ATX motherboards, measuring 13.6 inches by 13 inches compared to 12 inches by 9.6 inches. This size difference affects the number of components that can be accommodated on the motherboard.
Expansion Slots
ATX motherboards typically feature 7 to 10 expansion slots, including PCIe x16, PCIe x1, and PCI slots. EATX motherboards offer more expansion slots, usually 12 or more, which allows for greater flexibility in connecting multiple graphics cards, sound cards, and other peripherals.
Cooling Options
EATX motherboards typically provide enhanced cooling options compared to ATX motherboards. They feature larger heatsinks and additional fan headers to support high-performance components that generate more heat. This improved cooling is essential for maintaining system stability and preventing overheating.
Price and Availability
ATX motherboards are more widely available and generally less expensive than EATX motherboards. This is because ATX is a more popular form factor, with a wider range of options from different manufacturers. EATX motherboards are typically found in high-end systems and workstations, which drives up their price.
Which Motherboard Form Factor is Right for You?
The choice between an ATX and EATX motherboard depends on your specific needs and budget.
ATX:
- Ideal for most builds, including gaming, productivity, and general-purpose systems
- Offers a wide range of expansion slots and connectivity options
- More affordable and widely available
EATX:
- Designed for high-end systems and workstations that require maximum expansion and performance
- Provides more expansion slots, enhanced cooling options, and support for high-performance components
- More expensive and less widely available
Other Considerations
In addition to the key differences outlined above, there are a few other factors to consider when choosing between ATX and EATX motherboards:
- Case Compatibility: Ensure that the motherboard you choose is compatible with your chosen case. EATX motherboards require larger cases with ATX support.
- Budget: EATX motherboards are generally more expensive than ATX motherboards. Set a budget and consider the cost of the motherboard and other components.
- Features and Functionality: Different motherboards offer varying features and functionality. Compare the specific features of each motherboard to determine which one best meets your needs.
Key Points: Making an Informed Decision
Choosing between an ATX and EATX motherboard requires careful consideration of your specific requirements and budget. ATX motherboards offer a versatile and affordable option for most builds. EATX motherboards provide maximum expansion and performance for high-end systems and workstations. By understanding the differences between these two form factors and considering the factors discussed in this guide, you can make an informed decision that will optimize your PC build for your intended use.
Popular Questions
1. What is the main difference between ATX and EATX motherboards?
The main difference lies in their size and dimensions. EATX motherboards are larger than ATX motherboards, providing more space for expansion slots and other components.
2. Which form factor is better for gaming?
ATX motherboards are generally sufficient for gaming systems. However, if you require multiple graphics cards or other high-performance components, an EATX motherboard may be a better choice.
3. Can I use an ATX motherboard in an EATX case?
No, ATX motherboards are not compatible with EATX cases. EATX cases are designed for larger EATX motherboards, while ATX cases are specifically made for ATX motherboards.
