PSG has now won the season-opening trophy on fourteen different times.
Paris Saint-Germain required a dramatic leveler followed by a successful spot-kick decider to get past Marseille in Kuwait and capture a record-extending fourth consecutive French Super Cup title.
The European champions appeared to be sailing towards a comfortable triumph in the showdown featuring the Ligue 1 champions and the Coupe de France holders after the French winger opened the net early on.
Yet, Marseille fired two times in the closing moments to seize a shock advantage. First, Mason Greenwood converted from the spot-kick, before the defender inadvertently turned the ball into his own net for an own goal.
In a breathtaking twist of fortune, the Portuguese striker grabbed a crucial leveler in the final moments to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, saving crucial attempts from O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and the young talent all scored with composure for PSG to seal a convincing shootout win.
Now 14-time champions PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now won this competition for the twelfth time in the past thirteen years.
