PSG has now won the prestigious trophy on 14 separate occasions.
Paris Saint-Germain needed a dramatic leveler followed by a successful spot-kick decider to overcome Marseille in the Gulf and secure a fourth straight Trophee des Champions title.
The European champions seemed to be coasting towards a straightforward triumph in the match between the French league champions and the Coupe de France holders after the French winger found the net early on.
However, the southern French side fired two times late to seize a surprise advantage. Initially, Mason Greenwood converted from the penalty spot, before the defender inadvertently directed the ball into his own net for an own-goal.
In a remarkable turn of fortune, the Portuguese striker grabbed a crucial equaliser in the final seconds to send the contest into a penalty shootout. The Parisian shot-stopper Chevalier then stood as the hero, stopping decisive kicks from O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored with composure for Paris Saint-Germain to seal a convincing shootout win.
The record winners PSG, who met last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now lifted this trophy for the 12th time in the past 13 years.
