I don't know of any such device.  In any event  although you might put a
power supply module inside the box (assuming it meets code to do so), the
temperature sensing element at least would have to be on the outside,
open to the ambient air and probably somewhat remote so it's not
influenced by the heat from the power supply.  And you'd want the sensing
element to be around 5 feet off the floor, not down at the level of most
residential AC receptacles.
