The Parisian club has now won the prestigious cup on 14 separate occasions.
The Parisian giants required a dramatic leveler followed by a perfect penalty shootout to overcome Marseille in Kuwait and secure a record-extending fourth consecutive Trophee des Champions victory.
The European champions seemed to be coasting towards a straightforward win in the showdown between the French league champions and the Coupe de France winners after the French winger opened the scoring in the opening stages.
Yet, Marseille struck twice late to seize a shock lead. Initially, Mason Greenwood converted from the spot-kick, before the defender unfortunately turned the ball into his own net for an own goal.
In a remarkable twist of fortune, Goncalo Ramos grabbed a crucial equaliser in the dying moments to send the contest into a deciding shootout. The Parisian shot-stopper Chevalier then stood as the hero, saving decisive attempts from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted with composure for PSG to seal a 4-1 shootout win.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now lifted this competition for the 12th time in the last 13 seasons.
