PSG has now won the prestigious cup on 14 different occasions.
Paris Saint-Germain needed a dramatic equaliser followed by a successful spot-kick decider to get past Marseille in the Gulf and secure a fourth straight French Super Cup title.
The Champions League holders appeared to be sailing towards a comfortable triumph in the match between the French league champions and the French Cup holders after Ousmane Dembele found the net early on.
However, Marseille fired twice in the closing moments to take a shock advantage. Initially, the English forward converted from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a remarkable twist of events, Goncalo Ramos grabbed a crucial equaliser in the dying seconds to send the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, saving decisive attempts from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted successfully for Paris Saint-Germain to seal a convincing penalty win.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now won this trophy for the 12th time in the last 13 seasons.
