The Parisian club has now won the prestigious trophy on 14 different occasions.
The Parisian giants required a stoppage-time equaliser followed by a successful penalty shootout to overcome Marseille in Kuwait and capture a fourth straight Trophee des Champions victory.
The European champions appeared to be coasting towards a comfortable win in the showdown between the French league champions and the French Cup winners after Ousmane Dembele opened the scoring in the opening stages.
Yet, Marseille struck twice late to take a shock advantage. First, the English forward 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 events, the Portuguese striker snatched a vital equaliser in the final moments to send the match into a penalty shootout. The Parisian shot-stopper Chevalier then emerged as the hero, stopping decisive attempts from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all converted successfully for Paris Saint-Germain to seal a convincing shootout win.
The record champions PSG, who met last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now won this trophy for the 12th time in the last thirteen seasons.
