PSG has now secured the season-opening trophy on 14 different occasions.
Paris Saint-Germain required a stoppage-time leveler followed by a successful penalty shootout to overcome Marseille in Kuwait and secure a fourth straight Trophee des Champions title.
The Champions League holders appeared to be sailing towards a comfortable triumph in the match between the Ligue 1 champions and the French Cup holders after Ousmane Dembele found the scoring early on.
However, Marseille fired twice late to seize a surprise lead. First, Mason Greenwood converted from the penalty spot, before the defender unfortunately turned the ball into his own net for an own-goal.
In a remarkable twist of events, Goncalo Ramos grabbed a crucial leveler in the dying seconds to send the contest into a penalty shootout. PSG goalkeeper Chevalier then stood as the key figure, saving decisive kicks from O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and the young talent all scored with composure for PSG to complete a convincing shootout win.
Now 14-time winners PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a domestic double, have now won this competition for the twelfth time in the last thirteen seasons.
