Are you planning to build a PC all by yourself? In that case, you should think about one of the most important components and that is the motherboard.

A motherboard happens to be the backbone of a PC and it is available in different sizes. This includes eATX, ATX, Mini ATX, and Micro ATX. But if you are confused to choose between eATX and ATX, then this post is for you.

Just so you know ATX was released by Intel in 1995 and eATX is the bigger version which was launched much later. Users often get confused, while choosing between the two. To make the right choice, you need to first know the difference between the two. To help you out, we have laid down the differences between the two motherboard standards.

Difference Between eATX And ATX

Both ATX and eATX are the two standards used for sizing motherboards. Depending on which one you choose for your PC, it can make a big difference. We have laid down the difference in terms of size, performance, price, and other important factors. This should give you a clear idea about what you want.

1. Size

When it comes to size, eATX is a size bigger than ATX. eATX is 12 x 13 inch, whereas ATX is 12 x 9.6 inch. That’s because the former has a few inches extra on the sides.

eATX motherboards are generally used in servers. Since they come with some extra space, they can easily accommodate all the additional hardware that is required to operate a server.

To clear your confusion, eATX motherboards have a larger surface. This is why they are better at dissipating heat. Not just that, but they are also great for GPU because of all the extra space.

2. Functionality

Coming to the functionality part, eATX motherboards can fit in more ports because of the larger surface. For example, ATX motherboards have 3 to 4 PCIe x 16 ports, whereas eATX has 6 to 8. Not just that, but even the number of RAM slots is higher in eATX. For example, ATX comes with just 4 RAM slots, whereas eATX has 6 or 8 slots.

So if you want to install more than one graphics, then getting an eATX motherboard would be a good option for you. These boards have a lot of space for capture cards, graphics cards, and so on. Although you can install a graphics card in an eATX motherboard, how high you can go is dependent on the features offered by the board.

3. Performance

In terms of performance, both eATX and ATX motherboards are great. They give you top-notch performance regardless of their size. But there are other things that you need to look into. For example, if you want to overclock, then going for an eATX board would be a better option. That’s because an eATX can handle overclocking better because of its larger size.

Smaller boards like that of an ATX are usually made of inferior parts. In this case, overclocking may damage the board. When you overclock, the processor and the bus runs hotter. The fact that smaller boards have less surface area, they are unable to dissipate the heat properly. This makes it difficult to run the machine stable. Also, you will be needing more fans and water cooling systems to keep the temperature of the machine low. On the other hand, eATX boards are designed for larger cases with sophisticated cooling systems.

4. Price

Even price is an important factor when it comes to choosing the right motherboard. If you compare the prices of both types, you will find that eATX motherboards are more expensive. The reason is obvious. It has a larger surface and more components than an ATX motherboard.

However, that doesn’t mean you cannot find an affordable eATX. Some brands make cheaper eATX.

Another thing about eATX boards is that they come with an associated cost. That’s because you have to buy a larger case so that you can fit the board in. If you choose an eATX board, then this is something you should keep in mind.

Which one should you buy?

Choosing the right motherboard for your PC is very important. After all, it’s the centerpiece that is responsible for operating everything.

When choosing between ATX and eATX, you should keep their differences in mind. You need to pick a board that will meet your requirements. For example, if you want a board with more ports, then eATX is the option for you. But if you have a smaller case, then you should go for an ATX motherboard as it has a smaller size.

We have already pointed out the main differences between the two motherboard standards. The final choice boils down to your requirement. If you are on a limited budget and yet want to build a top-notch PC, then ATX would be perfect for you.

The thing is that both the board types are great in their ways. Now it’s up to you what you need.
