The Parisian club has now secured the prestigious cup on fourteen different occasions.
Paris Saint-Germain needed a stoppage-time equaliser followed by a successful penalty shootout to overcome 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 comfortable win in the showdown featuring the French league champions and the French Cup holders after the French winger found the scoring early on.
However, Marseille struck twice late to seize a shock lead. First, the English forward converted 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 snatched a crucial leveler in the dying moments to send the match into a penalty shootout. The Parisian shot-stopper Chevalier then stood as the hero, stopping decisive attempts from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored successfully for PSG to seal a 4-1 shootout win.
Now 14-time champions PSG, who met last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now won this competition for the twelfth time in the past 13 seasons.
