PSG has now claimed the prestigious trophy on 14 different occasions.
Paris Saint-Germain needed a dramatic leveler followed by a perfect spot-kick decider to get past Marseille in the Gulf and secure a fourth straight Trophee des Champions victory.
The European champions appeared to be coasting towards a straightforward triumph in the match between the French league champions and the French Cup holders after the French winger found the scoring early on.
Yet, the southern French side fired two times in the closing moments to take a surprise advantage. Initially, the English forward scored from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a breathtaking twist of events, the Portuguese striker snatched a vital leveler in the dying seconds to force the contest into a deciding shootout. The Parisian shot-stopper Chevalier then stood as the hero, saving decisive kicks from O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted with composure for Paris Saint-Germain to seal a 4-1 penalty win.
The record winners PSG, who faced last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now lifted this competition for the twelfth time in the past 13 seasons.
