The Parisian club has now claimed the prestigious trophy on 14 separate occasions.
The Parisian giants required a dramatic leveler followed by a successful penalty shootout to overcome their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions victory.
The Champions League holders seemed to be coasting towards a straightforward triumph in the showdown between the Ligue 1 champions and the French Cup holders after Ousmane Dembele found the scoring early on.
Yet, Marseille fired twice late to seize a shock advantage. Initially, Mason Greenwood scored from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own goal.
In a remarkable twist of events, the Portuguese striker grabbed a crucial leveler in the final moments to force the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, stopping crucial kicks from Matt O'Riley and Traore.
In the shootout, Ramos, Vitinha, the full-back, and the young talent all scored with composure for PSG to complete a 4-1 shootout win.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now won this competition for the 12th time in the past thirteen years.
