Applications

This form factor was standard in desktop PCs from the late 1990s through early 2000s. It suits ATX motherboards with 20-pin connectors, found in systems predating the 24-pin ATX12V standard. Commonly used in office workstations, light-duty servers, and industrial control systems of that era. Not compatible with modern systems requiring 24-pin connectors.
