The Parisian club has now secured the season-opening trophy on fourteen different occasions.
The Parisian giants needed a stoppage-time leveler followed by a successful penalty shootout to get past their arch-rivals in Kuwait and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be coasting towards a comfortable win in the match featuring the French league winners and the French Cup winners after Ousmane Dembele found the scoring early on.
Yet, Marseille struck twice in the closing moments to take a surprise lead. 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 turn of fortune, the Portuguese striker snatched a vital leveler in the final moments to force the match into a deciding shootout. PSG goalkeeper Chevalier then stood as the key figure, stopping decisive attempts from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, the full-back, and the young talent all converted with composure for PSG to complete a convincing penalty win.
Now 14-time champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now lifted this trophy for the twelfth time in the past 13 seasons.
