The Parisian club has now claimed the prestigious trophy on fourteen different occasions.
The Parisian giants needed a stoppage-time equaliser followed by a perfect penalty shootout to overcome Marseille in Kuwait and capture a fourth straight Trophee des Champions victory.
The Champions League holders appeared to be coasting towards a comfortable triumph in the match featuring the French league winners and the French Cup holders after the French winger opened the scoring early on.
However, the southern French side struck twice in the closing moments to seize a shock lead. Initially, 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 snatched a crucial equaliser in the dying moments to force the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, saving crucial kicks from O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored with composure for PSG to seal a convincing shootout win.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now lifted this competition for the 12th time in the past thirteen years.
