The Parisian club has now won the prestigious cup on 14 different times.
The Parisian giants required a stoppage-time leveler followed by a perfect penalty shootout to overcome Marseille in the Gulf and capture a fourth straight Trophee des Champions victory.
The Champions League holders appeared to be coasting towards a comfortable win in the showdown featuring the Ligue 1 winners and the Coupe de France holders after Ousmane Dembele opened the net early on.
Yet, the southern French side struck twice late to seize a surprise lead. Initially, the English forward scored from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own goal.
In a remarkable twist of fortune, Goncalo Ramos snatched a crucial leveler in the final seconds to force the match into a deciding shootout. PSG goalkeeper Chevalier then stood as the hero, saving decisive attempts from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and the young talent all scored successfully for PSG to seal a convincing shootout win.
Now 14-time champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now lifted this trophy for the twelfth time in the last thirteen seasons.
