PSG has now secured the prestigious trophy on fourteen different times.
Paris Saint-Germain required a dramatic equaliser followed by a successful spot-kick decider to overcome Marseille in the Gulf and capture a fourth straight Trophee des Champions title.
The European champions seemed to be sailing towards a comfortable win in the showdown between the Ligue 1 winners and the Coupe de France winners after the French winger found the net early on.
Yet, the southern French side fired two times late to take a shock lead. First, Mason Greenwood converted from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own goal.
In a remarkable twist of events, the Portuguese striker snatched a vital equaliser in the dying moments to force the match into a deciding shootout. PSG goalkeeper Chevalier then stood as the key figure, saving crucial attempts from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all scored with composure for PSG to seal a 4-1 penalty victory.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now won this trophy for the twelfth time in the past thirteen seasons.
