Buyer's Guide: Best Extended ATX Motherboards

Introduction

When it comes to building a high-performance PC, the motherboard is an essential component to consider. Extended ATX (E-ATX) motherboards offer more features and capabilities than standard ATX motherboards, making them a popular choice for enthusiasts and gamers. In this article, we'll go over some important factors to consider when choosing an E-ATX motherboard for your next build.

CPU Socket and Chipset

One of the first things to consider when choosing an E-ATX motherboard is the CPU socket and chipset. The CPU socket is the physical interface on the motherboard where the CPU is installed. It's important to make sure that the motherboard you choose is compatible with the CPU you plan on using. The chipset, on the other hand, is a set of electronic components that manages communication between the CPU and other components on the motherboard.

Memory Support

Another important factor to consider when choosing an E-ATX motherboard is the type and amount of memory it supports. E-ATX motherboards typically support more memory than standard ATX motherboards, so you'll have more flexibility when it comes to upgrading in the future. It's also important to consider the type of memory that the motherboard supports, as different CPUs and chipsets may require different types of memory.

Expansion Slots

E-ATX motherboards also offer more expansion slots than standard ATX motherboards, which is important if you plan on using multiple graphics cards or other expansion cards in your build. Make sure to check the number and type of expansion slots on the motherboard to ensure that it can accommodate your expansion card needs.

Connectivity Options

Another factor to consider when choosing an E-ATX motherboard is the connectivity options it offers. These can include USB ports, Ethernet ports, and audio jacks, among others. Make sure to check the number and type of connectivity options on the motherboard to ensure that it can support all of your peripherals and other devices.

Overclocking Support

Overclocking is the process of making the CPU and other components run at higher clock speeds than their default settings. E-ATX motherboards often offer more robust overclocking support than standard ATX motherboards, so they are a good choice if you plan on overclocking your CPU.

Conclusion

When it comes to choosing an E-ATX motherboard, there are several important factors to consider. Make sure to choose a motherboard that is compatible with your CPU and offers the memory, expansion, and connectivity options you need. Additionally, look for a motherboard with good overclocking support if you plan on pushing your components to their limits. With the right E-ATX motherboard, you can build a high-performance PC that can handle even the most demanding tasks.

Frequently Asked Questions (FAQs)

1. What is the difference between ATX and ATX extended?

The main difference between ATX and Extended ATX (EATX) motherboards is the size. EATX motherboards are larger, measuring 12 x 13 inches, which is 3.4 inches wider than ATX. This larger size allows for more components to be installed. However, it also means that EATX motherboards require a bigger case. The advantage of the bigger case is improved airflow.

2. What is EATX vs ATX board?

EATX (Extended ATX) is essentially a larger version of an ATX motherboard, offering more ports and expansion options. ATX motherboards are more affordable and popular among gamers. On the other hand, EATX motherboards are ideal for workstations due to their dual-socket capability and additional RAM slots. However, EATX motherboards are significantly more expensive than ATX motherboards.

3. Will an Extended ATX motherboard fit in a mid tower case?

In general, an Extended ATX (EATX) motherboard may not fit in a mid tower case. EATX motherboards typically require a full tower case for proper installation. It is important to carefully check the specifications and measurements of both the motherboard and the case before purchasing to ensure compatibility.

4. Why is EATX so expensive?

Extended ATX (EATX) cases are generally more expensive because they are larger and designed to accommodate the larger motherboard. The increased size and additional features contribute to the higher cost compared to more common ATX cases.

5. Does EATX fit in an ATX case?

In most cases, an EATX motherboard can fit in an ATX case with a minor overhang. However, the cable management area and overall tidiness may be compromised. It is recommended to choose a case specifically designed for EATX motherboards or opt for an ATX motherboard for better compatibility and aesthetics.

6. Can an ATX motherboard fit in a mid tower?

Yes, ATX motherboards can generally fit in most full-size and mid-size tower cases. However, it is rare to find a small form factor case that can accommodate a full-size ATX board. There are larger cases specifically designed to support Extended ATX (EATX) motherboards, which can usually accommodate ATX boards as well.
