The ATX Standard defines the physical dimensions, mounting points, power supply connectors, and input/output interface locations of motherboards and other components in personal computers. It allows interoperability and ensures components from different manufacturers are compatible when building or upgrading PCs, making it critical for system builders and integrators.
examples
An ATX motherboard measures 305 mm x 244 mm (12 in x 9.6 in) and fits inside a standard ATX case, connecting to an ATX power supply to receive 12V, 5V, and 3.3V power.
Commonly used in custom-built desktops due to its support for numerous components and expansions.
A standard ATX power supply provides power through a 24-pin connector and includes additional connectors for CPUs and GPUs, offering output ranges like 500W (Watts) to over 1000W.
Utilized in high-performance personal computer setups requiring reliable power delivery.
An ATX-compliant case features support for seven expansion slots and is designed with cooling options to accommodate high-performance builds.
Suitable for gaming rigs and workstations that require advanced cooling and easy component access.
