The Parisian club has now won the prestigious trophy on fourteen different occasions.
The Parisian giants required a stoppage-time leveler followed by a perfect penalty shootout to get past their arch-rivals in the Gulf and capture a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders appeared to be coasting towards a comfortable triumph in the match between the French league champions and the Coupe de France holders after Ousmane Dembele opened the scoring in the opening stages.
However, the southern French side fired two times late to seize a shock lead. Initially, Mason Greenwood converted from the spot-kick, before Willian Pacho 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 send the match into a penalty shootout. PSG goalkeeper Chevalier then stood as the hero, saving crucial kicks from O'Riley and Traore.
In the shootout, Ramos, Vitinha, the full-back, and the young talent all scored successfully for Paris Saint-Germain to complete a 4-1 shootout win.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now won this competition for the twelfth time in the last 13 seasons.
