Abstract: An information handling system includes a power supply configured to provide a main power bus and a secondary power bus and a USB-C port. The USB-C port includes a connector that provides an internal power bus, an input selector that couples the internal power bus to the main power bus, and a controller that enables/disables the coupling of the internal power bus to the main power bus by the input selector, and selectively couple the secondary power bus to the internal power bus. The controller further determines that an over-voltage condition is exhibited on the first internal power bus, and, in response to determining the over-voltage condition, disables the first input selector from coupling the first internal power bus to the main power bus and uncouples the secondary power bus from the first internal power bus.
