The Parisian club has now won the prestigious cup on fourteen separate occasions.
The Parisian giants needed a dramatic equaliser followed by a successful penalty shootout to get past their arch-rivals in the Gulf and secure a fourth straight French Super Cup title.
The European champions seemed to be coasting towards a straightforward triumph in the showdown between the French league champions and the Coupe de France winners after Ousmane Dembele opened the scoring early on.
Yet, Marseille struck twice late to take a surprise lead. Initially, Mason Greenwood converted from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a remarkable turn of events, Goncalo Ramos snatched a vital leveler in the dying moments to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping decisive attempts from O'Riley and Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and the young talent all converted with composure for Paris Saint-Germain to seal a convincing shootout victory.
Now 14-time champions Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now lifted this trophy for the twelfth time in the last thirteen seasons.
