The Parisian club has now secured the season-opening cup on fourteen separate times.
Paris Saint-Germain required a stoppage-time equaliser followed by a successful spot-kick decider to get past Marseille in the Gulf and secure a fourth straight French Super Cup victory.
The Champions League holders seemed to be coasting towards a comfortable win in the showdown between the French league winners and the Coupe de France winners after Ousmane Dembele opened the net in the opening stages.
However, Marseille struck two times in the closing moments to seize a shock advantage. 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 twist of fortune, Goncalo Ramos grabbed a vital leveler in the final seconds to send the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, saving decisive kicks from Matt O'Riley and Traore.
In the shootout, Ramos, Vitinha, the full-back, and the young talent all converted with composure for Paris Saint-Germain to seal a convincing shootout win.
Now 14-time champions PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now won this competition for the 12th time in the last 13 years.
