PSG has now claimed the prestigious trophy on 14 separate occasions.
Paris Saint-Germain required a dramatic leveler followed by a successful spot-kick decider to overcome their arch-rivals in Kuwait 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 champions and the French Cup winners after the French winger opened the scoring in the opening stages.
Yet, Marseille fired twice late to seize a surprise lead. First, Mason Greenwood scored from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a remarkable turn of fortune, the Portuguese striker snatched a vital equaliser in the final seconds to send the contest into a penalty shootout. PSG goalkeeper Chevalier then stood as the hero, stopping decisive kicks from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted with composure for PSG to seal a convincing shootout victory.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now lifted this trophy for the twelfth time in the past thirteen seasons.
