PSG has now won the prestigious cup on fourteen different times.
The Parisian giants required a stoppage-time equaliser followed by a perfect penalty shootout to overcome Marseille in the Gulf and secure a record-extending fourth consecutive French Super Cup title.
The European champions seemed to be sailing towards a comfortable win in the match featuring the French league winners and the Coupe de France winners after the French winger opened the scoring in the opening stages.
However, Marseille fired two times in the closing moments to seize a surprise advantage. Initially, Mason Greenwood scored from the spot-kick, before the defender unfortunately turned the ball into his own net for an own-goal.
In a remarkable twist of fortune, the Portuguese striker snatched a crucial leveler in the dying moments to force the contest into a deciding shootout. The Parisian shot-stopper Chevalier then emerged as the key figure, stopping crucial kicks from O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to seal a 4-1 penalty victory.
The record champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now lifted this competition for the 12th time in the past thirteen seasons.
