An apparatus for routing power between a set of power supply taps of an automated tester and power connections on an integrated circuit under test, where the integrated circuit belongs to a family of integrated circuits that have a common power connection layout and different power connection voltage requirements. An interface board having first electrical contacts disposed in the common power connection layout makes electrical connections to the power connections of all integrated circuits belonging to the family of integrated circuits. The first electrical contacts are electrically routed to second electrical contacts disposed in a standardized configuration. A power personality card having third electrical contacts makes electrical connections to the second electrical contacts of the interface board. Fourth electrical contacts are disposed in a standardized configuration, and the third electrical contacts are electrically routed to the fourth electrical contacts via electrical lines that are hard wired for the power connection voltage requirements of the integrated circuit under test. The power personality card and the interface board are interchangeable, one with another. Power supply taps make electrical connections to the fourth electrical contacts and provide power to the fourth electrical contacts.
