The Parisian club has now won the prestigious cup on 14 different times.
The Parisian giants required a dramatic equaliser followed by a successful penalty shootout to get past their arch-rivals in Kuwait and capture a fourth straight Trophee des Champions title.
The Champions League holders appeared to be coasting towards a comfortable triumph in the showdown featuring the French league winners and the Coupe de France winners after Ousmane Dembele found the scoring in the opening stages.
Yet, the southern French side fired two times in the closing moments to take a shock advantage. Initially, Mason Greenwood scored from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a breathtaking twist of events, the Portuguese striker snatched a crucial equaliser in the final seconds to force the match into a penalty shootout. PSG goalkeeper Chevalier then emerged as the hero, stopping decisive kicks from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and the young talent all scored successfully for PSG to complete a convincing penalty victory.
Now 14-time winners PSG, who met 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 thirteen seasons.
