PSG has now secured the season-opening trophy on fourteen different occasions.
Paris Saint-Germain needed a stoppage-time leveler followed by a perfect spot-kick decider 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 match between the French league winners and the French Cup holders after the French winger found the net early on.
Yet, Marseille struck twice in the closing moments to take a shock lead. Initially, the English forward scored from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a remarkable turn of events, the Portuguese striker snatched a vital leveler in the final seconds to send the contest into a deciding shootout. PSG goalkeeper Chevalier then stood as the hero, saving crucial kicks from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and Desire Doue all scored with composure for Paris Saint-Germain to complete a 4-1 penalty victory.
The record winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now won this competition for the 12th time in the last 13 seasons.
