PSG has now claimed the season-opening trophy on 14 separate occasions.
Paris Saint-Germain needed a stoppage-time leveler followed by a successful penalty shootout to get past Marseille in the Gulf and capture a record-extending fourth consecutive French Super Cup victory.
The Champions League holders appeared to be coasting towards a comfortable triumph in the showdown featuring the French league champions and the Coupe de France holders after the French winger opened the scoring in the opening stages.
Yet, Marseille struck twice in the closing moments to take a surprise advantage. Initially, Mason Greenwood scored from the penalty spot, before the defender unfortunately directed the ball into his own net for an own goal.
In a remarkable twist of fortune, the Portuguese striker grabbed a vital leveler in the final seconds to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, saving crucial kicks from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and the young talent all converted successfully for PSG to seal a convincing shootout victory.
The record winners Paris Saint-Germain, 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 12th time in the last thirteen seasons.
