PSG has now won the prestigious cup on 14 different times.
The Parisian giants needed a dramatic leveler followed by a successful penalty shootout to overcome their arch-rivals in the Gulf and secure a fourth straight Trophee des Champions title.
The Champions League holders seemed to be sailing towards a comfortable win in the match between the Ligue 1 winners and the Coupe de France winners after the French winger found the scoring early on.
Yet, Marseille struck two times late to seize a surprise lead. First, Mason Greenwood converted from the spot-kick, before the defender inadvertently turned the ball into his own net for an own-goal.
In a remarkable twist of fortune, Goncalo Ramos snatched a crucial leveler in the final seconds to force the match into a deciding shootout. PSG goalkeeper Chevalier then stood as the hero, stopping crucial attempts from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored with composure for Paris Saint-Germain to seal a convincing penalty win.
Now 14-time winners PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a league and cup double, have now lifted this trophy for the twelfth time in the last 13 seasons.
