When it comes to building or upgrading a computer, one of the most critical components to consider is the power supply unit (PSU). The PSU is responsible for providing power to all the components in the system, and its form factor plays a significant role in determining the overall size and layout of the computer case. Among the various power supply form factors available, Micro-ATX has gained popularity in recent years due to its compact size and versatility. In this article, we will delve into the details of the Micro-ATX power supply form factor, its characteristics, and its applications.
Introduction to Micro-ATX Power Supply
The Micro-ATX power supply form factor is a variant of the standard ATX form factor, which was introduced by Intel in 1995. The Micro-ATX form factor was designed to provide a more compact and efficient power supply solution for smaller computer cases. It measures 171.45 mm (6.75 inches) in width, 85.6 mm (3.37 inches) in height, and 63.5 mm (2.5 inches) in depth, making it significantly smaller than the standard ATX power supply. Despite its smaller size, the Micro-ATX power supply is capable of delivering the same level of power and performance as its larger counterpart.
