Giovani Lo Celso hit the post twice before opening the scoring and Edinson Cavani needed a penalty for PSG to see off Les Herbiers.
Paris Saint-Germain claimed their third domestic treble in four seasons as Giovani Lo Celso and Edinson Cavani sunk gallant minnows Les Herbiers 2-0 in the final of the Coupe de France.
The third-tier side stuck gamely to the task of tackling French football's all-conquering force having made it to the Stade de France without facing Ligue 1 opposition.
Argentina midfielder Lo Celso struck the post twice before opening the scoring and, in the second half, Les Herbiers goalkeeper Matthieu Pichot came to the fore with a string of superb saves.
