The Parisian club has now secured the prestigious trophy on 14 different occasions.
The Parisian giants needed a dramatic leveler followed by a successful spot-kick decider to get past Marseille in Kuwait and secure a fourth straight Trophee des Champions victory.
The European champions appeared to be coasting towards a comfortable triumph in the match between the French league winners and the French Cup holders after the French winger opened the scoring in the opening stages.
Yet, Marseille struck twice in the closing moments to take a shock advantage. First, the English forward scored from the penalty spot, before the defender unfortunately directed the ball into his own net for an own-goal.
In a remarkable turn of events, the Portuguese striker grabbed a crucial equaliser in the dying moments to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping crucial attempts from Matt O'Riley and Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored with composure for Paris Saint-Germain to complete a convincing penalty victory.
Now 14-time winners PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after achieving a league and cup double, have now lifted this trophy for the twelfth time in the past thirteen seasons.
