The Parisian club has now secured the prestigious trophy on 14 different times.
The Parisian giants needed a dramatic leveler followed by a successful penalty shootout to overcome Marseille in Kuwait and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be sailing towards a straightforward triumph in the match featuring the French league winners and the Coupe de France holders after Ousmane Dembele opened the net in the opening stages.
However, the southern French side struck two times late to take a shock lead. First, Mason Greenwood scored from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a remarkable twist of events, the Portuguese striker snatched a vital leveler in the dying moments to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping decisive kicks from O'Riley and Traore.
In the shootout, Ramos, Vitinha, the full-back, and the young talent all converted successfully for Paris Saint-Germain to seal a 4-1 shootout win.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now won this competition for the twelfth time in the past 13 years.
