The Parisian club has now secured the prestigious cup on 14 different occasions.
Paris Saint-Germain needed a dramatic leveler followed by a perfect spot-kick decider to get past Marseille in Kuwait and secure a fourth straight Trophee des Champions title.
The Champions League holders seemed to be coasting towards a comfortable win in the showdown between the French league champions and the Coupe de France holders after the French winger opened the scoring in the opening stages.
Yet, Marseille fired two times late to seize a surprise lead. First, the English forward scored from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a remarkable turn of events, the Portuguese striker snatched a crucial leveler in the final moments to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, saving crucial attempts from O'Riley and Traore.
In the shootout, Ramos, Vitinha, the full-back, and the young talent all converted with composure for PSG to seal a 4-1 penalty win.
The record champions PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a domestic double, have now lifted this competition for the 12th time in the last 13 seasons.
