PSG has now secured the prestigious cup on fourteen separate occasions.
The Parisian giants needed a dramatic equaliser followed by a successful penalty shootout to overcome Marseille in the Gulf and secure a record-extending fourth consecutive French Super Cup victory.
The Champions League holders appeared to be coasting towards a straightforward triumph in the match between the French league champions and the Coupe de France holders after Ousmane Dembele opened the net early on.
Yet, Marseille struck twice in the closing moments to take a shock advantage. First, the English forward converted from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own goal.
In a remarkable twist of fortune, the Portuguese striker snatched a vital equaliser in the final moments to force the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, saving decisive kicks from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and the young talent all converted with composure for Paris Saint-Germain to complete a convincing shootout victory.
Now 14-time winners PSG, who faced last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now won this trophy for the twelfth time in the last thirteen years.
