The Parisian club has now claimed the prestigious cup on 14 separate times.
The Parisian giants needed a stoppage-time equaliser followed by a perfect spot-kick decider to overcome Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders seemed to be sailing towards a straightforward triumph in the showdown between the French league winners and the French Cup winners after Ousmane Dembele opened the scoring early on.
Yet, the southern French side fired twice late to seize a shock lead. Initially, the English forward converted from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a breathtaking twist of events, Goncalo Ramos snatched a vital equaliser in the final moments to force the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, saving decisive attempts from Matt O'Riley and Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and the young talent all converted with composure for Paris Saint-Germain to seal a convincing penalty victory.
Now 14-time winners PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now won this trophy for the twelfth time in the last 13 seasons.
