PSG has now claimed the season-opening trophy on fourteen separate times.
Paris Saint-Germain needed a dramatic leveler followed by a successful spot-kick decider to overcome Marseille in the Gulf and capture a record-extending fourth consecutive French Super Cup victory.
The Champions League holders appeared to be sailing towards a straightforward triumph in the showdown featuring the French league winners and the Coupe de France holders after the French winger opened the net in the opening stages.
However, Marseille struck twice in the closing moments to seize a shock advantage. Initially, Mason Greenwood converted from the penalty spot, before the defender unfortunately directed the ball into his own net for an own-goal.
In a remarkable twist of events, Goncalo Ramos snatched a crucial equaliser in the final moments to force the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, saving crucial kicks from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored with composure for PSG to complete a convincing shootout victory.
The record winners PSG, who met last season's Ligue 1 runners-up Marseille after completing a domestic double, have now lifted this competition for the twelfth time in the last thirteen years.
