PSG has now secured the season-opening trophy on 14 different times.
Paris Saint-Germain required a dramatic equaliser followed by a perfect spot-kick decider to overcome Marseille in the Gulf and secure a fourth straight French Super Cup title.
The European champions seemed to be coasting towards a comfortable win in the showdown featuring the Ligue 1 winners and the French Cup winners after Ousmane Dembele found the net early on.
Yet, the southern French side struck two times in the closing moments to take a shock advantage. Initially, Mason Greenwood scored from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own goal.
In a breathtaking twist of events, Goncalo Ramos grabbed a vital leveler in the final moments to force the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, stopping decisive attempts from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and the young talent all converted with composure for PSG to seal a convincing shootout victory.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Olympique de Marseille after achieving a domestic double, have now won this competition for the 12th time in the past 13 years.
