Molex originated a large variety of connector types, but only one is commonly used in microcomputers, and thus known unambiguously as a "Molex connector" in that context. That connector type is the one pictured, which is used for power connections for disk drives and other computer components. An AT or ATX standard power supply normally has multiple connectors of this type.
