Final answer:
The model of presidential power where the president is limited to powers specifically stated in the Constitution is the enumerated (or specified) powers model.
Step-by-step explanation:
The presidential power model in which the president is limited to the particular powers articulated in the Constitution and cannot act beyond them is known as the enumerated (or specified) powers model. This model is based on the concept that the president's authority is confined to those powers expressly stated in Article II of the Constitution and those that are necessary to carry out those specified functions. According to this strict interpretation, any power that is not explicitly mentioned is not within the president's domain and would require an amendment to the Constitution or statutory authorization by Congress to be exercised by the president.
