The Parisian club has now secured the prestigious cup on 14 different occasions.
The Parisian giants required a stoppage-time equaliser followed by a successful penalty shootout to overcome Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders seemed to be coasting towards a straightforward win in the match between the French league winners and the Coupe de France holders after Ousmane Dembele opened the scoring in the opening stages.
Yet, Marseille struck twice late to take a surprise lead. First, Mason Greenwood scored from the spot-kick, before the defender inadvertently directed the ball into his own net for an own goal.
In a remarkable turn of fortune, Goncalo Ramos grabbed a crucial equaliser in the dying seconds to send the match into a deciding shootout. PSG goalkeeper Chevalier then stood as the hero, stopping crucial attempts from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted with composure for Paris Saint-Germain to complete a 4-1 shootout win.
The record winners PSG, who faced 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 thirteen years.
