The Parisian club has now claimed the prestigious trophy on fourteen different times.
The Parisian giants needed a dramatic leveler followed by a perfect penalty shootout to overcome Marseille in the Gulf and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be sailing towards a comfortable triumph in the showdown between the French league champions and the Coupe de France winners after Ousmane Dembele found the scoring early on.
Yet, Marseille struck twice late to take a surprise advantage. First, Mason Greenwood scored from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a remarkable twist of events, Goncalo Ramos snatched a vital leveler in the dying moments to send the match into a penalty shootout. The Parisian shot-stopper Chevalier then stood as the hero, saving decisive attempts from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and the young talent all converted successfully for PSG to seal a convincing penalty win.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now won this trophy for the 12th time in the last 13 seasons.
