PSG has now claimed the prestigious trophy on fourteen different times.
The Parisian giants required a dramatic leveler followed by a successful spot-kick decider to overcome their arch-rivals in the Gulf and secure a fourth straight French Super Cup title.
The Champions League holders seemed to be sailing towards a straightforward triumph in the showdown featuring the French league champions and the Coupe de France holders after Ousmane Dembele found the scoring early on.
However, Marseille struck twice in the closing moments to seize a surprise lead. Initially, Mason Greenwood scored from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a remarkable turn of events, the Portuguese striker snatched a crucial leveler in the final moments to force the match into a penalty shootout. PSG goalkeeper Chevalier then stood as the key figure, saving decisive kicks from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to complete a convincing shootout victory.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after completing a domestic double, have now lifted this trophy for the 12th time in the last thirteen years.
