ATX Motherboards


Asus TUF Gaming B650-Plus (Socket AM5) DDR5 ATX Motherboard

Explore a wide selection of ATX motherboards, suitable for any budget from manufacturers including ASUS, Gigabyte, MSI, and ASRock. Our range includes Intel and AMD models, covering a variety of chipsets and sockets, such as LGA 1700 Z790, AM4 B550, and AM5 X670. The Advanced Technology eXtended (ATX) form factor was first introduced in 1995 by Intel. Since then, it has become one of the most popular motherboard sizes available, thanks to its highly versatile design, extensive feature set, and widespread compatibility with gaming hardware. An ATX motherboard typically measures 305mm x 244mm (HxW), allowing them to be utilised in mid-tower or larger PC cases. They offer excellent support for gaming hardware, including multiple RAM DIMM slots, high-speed expansion slots, and blazing-fast storage through M.2 ports, each powered by the latest PCIe Gen 4 or 5 standards.


Advantages of an ATX motherboard

An ATX motherboard is one of the most utilised form factors used in gaming PCs. There are several reasons that make this model so popular. Some of these are:

  • Size The ATX motherboard size offers much more real estate compared to smaller form factors, like Mini-ITX and Micro-ATX. The extra space allows for more embed features, such as increased PCIe lanes, additional internal headers for power and RGB, improved power delivery, and extra SATA ports.
  • Component choices An ATX motherboard has four or more DIMM slots for RAM, multiple PCIe expansion slots, and extensive storage options including M.2 and SATA ports. This optimises compatibility with a wider selection of hardware from the current component market.
  • Cooling Because components on an ATX motherboard are more spaced apart, there is room for natural airflow to occur. Thanks to this, your hardware is better able to dissipate waste heat into the surrounding air. Additionally, as ATX motherboards are utilised in larger cases, they can generally utilise a wider range of cooling hardware, making it easier to maintain optimum thermals.
  • User Friendly As ATX is such a common form factor, PC case manufacturers use it as their default. As a result, many cases will feature pre-installed motherboard standoffs that match the layout of the ATX standard, simplifying the mounting process. Another advantage is that, an ATX motherboard is easier to build with as the extra space gives you better access to your hardware.
