PSG has now won the season-opening cup on fourteen separate occasions.
The Parisian giants needed a dramatic leveler followed by a successful spot-kick decider to overcome Marseille in the Gulf and secure a fourth straight Trophee des Champions victory.
The Champions League holders seemed to be coasting towards a comfortable triumph in the match between the French league champions and the Coupe de France winners after the French winger opened the scoring early on.
Yet, Marseille struck two times in the closing moments to seize a surprise advantage. First, the English forward scored from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a remarkable turn of events, the Portuguese striker grabbed a vital equaliser in the final moments to force the contest into a deciding shootout. PSG goalkeeper Chevalier then emerged as the hero, saving crucial kicks from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted with composure for Paris Saint-Germain to complete a convincing penalty win.
Now 14-time winners PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now won this trophy for the twelfth time in the last 13 seasons.
