The Parisian club has now claimed the season-opening trophy on fourteen different occasions.
The Parisian giants required a dramatic leveler followed by a perfect spot-kick decider to get past their arch-rivals in the Gulf and secure a fourth straight Trophee des Champions victory.
The European champions appeared to be sailing towards a comfortable triumph in the showdown featuring the French league winners and the French Cup winners after the French winger found the scoring in the opening stages.
Yet, Marseille struck twice in the closing moments to seize a shock advantage. 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 breathtaking twist of fortune, the Portuguese striker snatched a crucial equaliser in the final moments to force the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, stopping crucial kicks from O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted successfully for PSG to complete a convincing shootout 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 lifted this competition for the twelfth time in the last thirteen years.
