PSG has now secured the prestigious trophy on fourteen different times.
Paris Saint-Germain needed a stoppage-time leveler followed by a successful spot-kick decider to overcome their arch-rivals in the Gulf and secure a fourth straight Trophee des Champions title.
The European champions appeared to be sailing towards a comfortable triumph in the match between the French league winners and the Coupe de France holders after the French winger opened the scoring early on.
However, Marseille fired twice late to seize a surprise lead. Initially, the English forward converted from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a remarkable twist of fortune, Goncalo Ramos snatched a crucial equaliser in the final seconds to send the match into a deciding shootout. The Parisian shot-stopper Chevalier then stood as the key figure, stopping crucial kicks from Matt O'Riley and Traore.
From the spot, Ramos, Vitinha, the full-back, and the young talent all scored with composure for Paris Saint-Germain to complete a 4-1 penalty victory.
Now 14-time winners PSG, who met last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now lifted this competition for the twelfth time in the last thirteen years.
