PSG has now claimed the prestigious trophy on 14 separate times.
The Parisian giants required a dramatic equaliser followed by a perfect spot-kick decider to get past Marseille in Kuwait and capture a fourth straight Trophee des Champions title.
The Champions League holders seemed to be coasting towards a comfortable win in the match between the French league champions and the Coupe de France holders after the French winger found the scoring early on.
Yet, Marseille struck twice in the closing moments to seize a surprise advantage. First, Mason Greenwood scored from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a breathtaking twist of fortune, the Portuguese striker snatched a crucial leveler in the final moments to force the match into a penalty shootout. PSG goalkeeper Chevalier then stood as the key figure, stopping decisive kicks from O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to seal a convincing penalty victory.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now won this competition for the 12th time in the past thirteen years.
