PSG has now won the prestigious trophy on 14 separate occasions.
Paris Saint-Germain needed a stoppage-time leveler followed by a successful penalty shootout 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 straightforward triumph in the match between the French league winners and the Coupe de France holders after the French winger found the scoring in the opening stages.
However, Marseille struck two times late to take a surprise advantage. First, the English forward scored from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a remarkable twist of fortune, the Portuguese striker snatched a crucial equaliser in the final moments to send the match into a penalty shootout. The Parisian shot-stopper Chevalier then stood as the key figure, stopping decisive kicks from O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and Desire Doue all converted successfully for Paris Saint-Germain to seal a convincing penalty victory.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Olympique de Marseille after achieving a domestic double, have now lifted this competition for the twelfth time in the past thirteen seasons.
