The Parisian club has now secured the season-opening cup on 14 separate times.
The Parisian giants required a dramatic leveler followed by a successful spot-kick decider to overcome their arch-rivals in the Gulf and secure a fourth straight Trophee des Champions victory.
The Champions League holders seemed to be coasting towards a straightforward triumph in the match between the French league winners and the French Cup winners after Ousmane Dembele found the scoring early on.
However, Marseille fired two times in the closing moments to take a shock advantage. First, the English forward scored from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a breathtaking turn of events, the Portuguese striker grabbed a crucial leveler in the final seconds to force the match into a deciding shootout. The Parisian shot-stopper Chevalier then stood as the hero, saving crucial kicks from Matt O'Riley and Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to complete a convincing shootout victory.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now won this competition for the 12th time in the past 13 seasons.
