List of Features to Look for When Buying Your Motherboard


Check the motherboard’s chipset. This is a vital part of your motherboard, as it determines how fast and responsive your computer will be.


When checking the specs, look at the form factor of your motherboard. If you want to use an older CPU socket or have special needs that require a certain kind of layout (like a liquid cooler), make sure that this is available with your new purchase.


Check for compatibility with RAM slots. You can use more than one type at once. However, there are some cases where only one type will work on any given system, and these vary from manufacturer to manufacturer, so check before buying.

A USB 3.0 Header

If your motherboard has a USB 3.0 header, it means that it supports faster data transfer rates than standard USB 2.0 ports. It is because the old standard used to use only one type of cable and connector, whereas USB 3.0 uses both types together (USB Type-A and Type-C).

So what does this mean for you? Well, it could mean faster downloads from your computer or external drives if your motherboard supports this feature.
