What is micro atx?

Micro ATX (mATX) is a smaller form factor for motherboards, designed to fit into smaller cases compared to standard ATX motherboards. The dimensions of a micro ATX motherboard are typically 9.6 x 9.6 inches, making it slightly smaller than a standard ATX motherboard.

Micro ATX motherboards are popular among users who want a smaller and more compact computer build, such as in small form factor PCs or HTPCs (Home Theater PC). Despite their smaller size, micro ATX motherboards have most of the same features and capabilities as standard ATX motherboards, including support for multiple RAM slots, PCIe slots, and USB ports.

One disadvantage of micro ATX motherboards is that they may have fewer expansion slots compared to standard ATX motherboards, which can limit the number of additional components or devices that can be added to the system. However, for most users, a micro ATX motherboard will offer all the necessary features and performance for their computing needs.

Overall, micro ATX motherboards provide a good balance of performance, features, and size, making them a popular choice for many PC builders.
