A method and apparatus directed to detecting and preventing excessive heating in power connectors is disclosed. In one embodiment, a system includes a power connector having an array of pins. A circuit board, such as a midplane of a blade server chassis, has an array of electrical vias passing through the circuit board that are arranged to receive the array of pins and at least one heat flux sensor positioned on one of the vias at the back of the midplane. The heat flux sensor is configured for generating an electrical signal in relation to an applied heat flux. A controller in communication with the heat flux sensor is configured for powering off the electrical power supply in response to the electrical signal reaching a setpoint corresponding to a selected heat flux threshold.
