When it comes to selecting a motherboard, there are several form factors to consider, the most popular of which being ATX and Micro-ATX.
In this article, we will explore the differences between ATX and Micro-ATX and help you decide which one is best for your needs.
What Is The Difference Between ATX & Micro-ATX Motherboards In 2023?
Form Factor
The size and shape of a motherboard are referred to as its form factor. ATX (Advanced Technology eXtended) and Micro-ATX are two of the most prevalent desktop computer form factors. At 305mm x 244mm, the ATX form size is bigger than the Micro-ATX form factor. Micro-ATX motherboards, on the other hand, are substantially smaller, measuring 244mm x 244mm.
Expansion Slots
The number of expansion slots is one of the primary differences between ATX and Micro-ATX motherboards. Graphics cards, sound cards, and network cards can all be connected to the motherboard via expansion slots. You can install more expansion cards if necessary because ATX motherboards often have more expansion slots than Micro-ATX motherboards.
Micro-ATX motherboards include four expansion slots, compared to seven on ATX motherboards. This does not, however, imply that the expansion capabilities of Micro-ATX motherboards are constrained. With two or three PCIe x16 slots for graphics cards and one or two PCIe x1 slots for other expansion cards, the majority of contemporary Micro-ATX motherboards still provide enough expansion slots to meet the demands of the majority of customers.
Connectors
The amount of connections on ATX and Micro-ATX motherboards is another distinction. Because of their bigger size, ATX motherboards often include more connections than Micro-ATX motherboards. ATX motherboards, for example, often include more SATA connections for connecting storage devices, more USB ports, and more fan headers for system cooling.
Nevertheless, this does not imply that Micro-ATX motherboards lack connection. Most recent Micro-ATX motherboards still include a plethora of connections, such as several SATA ports, USB ports, and fan headers. They may not have as many connections as ATX motherboards, but they are more than enough for the majority of users’ needs.
Power Delivery
Power delivery is another consideration when deciding between ATX and Micro-ATX motherboards. The power delivery system on a motherboard is in charge of delivering consistent and dependable power to the CPU and other components. Because of their greater size and increased power use, ATX motherboards often feature more robust power supply systems than Micro-ATX motherboards.
ATX motherboards are therefore better suited for high-end systems with strong Processors and many graphics cards. Yet, most recent Micro-ATX motherboards still have adequate power supply systems capable of supporting mid-range CPUs and single graphics cards.
Price
Lastly, while deciding between ATX and Micro-ATX motherboards, pricing is an important consideration. Because of their greater size and more advanced functionality, ATX motherboards are often more expensive than Micro-ATX motherboards. This is especially true for high-end ATX motherboards geared for gaming or workstation applications.
Micro-ATX motherboards, on the other hand, are often less expensive, making them a popular choice for price-conscious customers. They don’t have as many features or expansion choices as ATX motherboards, but they can still run most desktop software and games.
Wrap Up! Which is best?
Finally, the decision between ATX and Micro-ATX motherboards is ultimately determined by your demands and budget. An ATX motherboard is the way to go if you’re creating a high-end system with several graphics cards and need a strong power supply system. A Micro-ATX motherboard, on the other hand, is a more cost-effective alternative if you are on a tight budget and do not want as many expansion possibilities.
It is crucial to remember that both ATX and Micro-ATX motherboards provide adequate connection and power supply systems for the majority of users. Finally, it boils down to personal choice and your system’s individual requirements.
FAQ’s
Can you use a Micro-ATX motherboard in an ATX case?
Yes, a Micro-ATX motherboard may be used in an ATX enclosure. ATX cases are intended to accept both ATX and Micro-ATX motherboards, thus compatibility is not an issue.
Can an ATX power supply be used with a Micro-ATX motherboard?
Yes, an ATX power supply may be used with a Micro-ATX motherboard. Because ATX and Micro-ATX motherboards utilize the same power connections, there is no incompatibility.
Do Micro-ATX motherboards have fewer features than ATX motherboards?
Micro-ATX motherboards often have fewer expansion slots and ports than ATX motherboards, but they nevertheless provide adequate features for the majority of users. Current Micro-ATX motherboards feature sufficient connection and power supply systems to support mid-range CPUs and single graphics cards with ease.
