PSG has now secured the prestigious cup on fourteen different times.
The Parisian giants needed a stoppage-time equaliser followed by a successful penalty shootout to overcome Marseille in the Gulf and capture a fourth straight French Super Cup title.
The Champions League holders appeared to be coasting towards a straightforward triumph in the showdown between the Ligue 1 winners and the French Cup winners after Ousmane Dembele found the scoring in the opening stages.
Yet, Marseille fired two times late to take a surprise lead. First, Mason Greenwood scored from the spot-kick, before the defender unfortunately turned the ball into his own net for an own-goal.
In a breathtaking turn of events, the Portuguese striker snatched a crucial leveler in the dying moments to force the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, saving crucial attempts from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and the young talent all converted successfully for Paris Saint-Germain to seal a convincing shootout victory.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now lifted this competition for the 12th time in the last 13 seasons.
