The Parisian club has now won the prestigious cup on fourteen different times.
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 fourth straight French Super Cup victory.
The European champions appeared to be sailing towards a straightforward triumph in the showdown featuring the French league winners and the Coupe de France holders after the French winger opened the net early on.
However, Marseille struck twice late to seize a surprise lead. Initially, Mason Greenwood converted from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a breathtaking twist of events, the Portuguese striker snatched a vital equaliser in the dying moments to force the match into a deciding shootout. PSG goalkeeper Chevalier then stood as the key figure, saving crucial attempts from O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and Desire Doue all scored with composure for Paris Saint-Germain to seal a convincing penalty win.
Now 14-time champions PSG, who faced last season's Ligue 1 runners-up Marseille after completing a domestic double, have now won this trophy for the twelfth time in the last 13 years.
