PSG has now won the season-opening cup on 14 different times.
Paris Saint-Germain needed a dramatic leveler followed by a perfect penalty shootout to get past Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders appeared to be sailing towards a straightforward triumph in the match between the French league winners and the French Cup winners after the French winger found the scoring early on.
However, Marseille struck twice in the closing moments to take a shock advantage. First, Mason Greenwood scored from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a remarkable turn of events, the Portuguese striker grabbed a crucial leveler in the dying moments to send the match into a penalty shootout. PSG goalkeeper Chevalier then emerged as the key figure, saving decisive kicks from Matt O'Riley and Traore.
From the spot, Ramos, Vitinha, the full-back, and Desire Doue all scored successfully for Paris Saint-Germain to seal a 4-1 penalty victory.
The record winners PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a league and cup double, have now won this competition for the 12th time in the last thirteen years.
