The Parisian club has now secured the prestigious cup on fourteen different occasions.
Paris Saint-Germain required a dramatic leveler followed by a successful penalty shootout to overcome Marseille in Kuwait and secure a fourth straight Trophee des Champions title.
The Champions League holders appeared to be coasting towards a straightforward win in the showdown between the French league champions and the Coupe de France winners after Ousmane Dembele opened the scoring in the opening stages.
Yet, the southern French side struck twice in the closing moments to take a surprise lead. Initially, the English forward converted from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a breathtaking turn of fortune, Goncalo Ramos grabbed a crucial equaliser in the final seconds to force the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, saving decisive attempts from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and Desire Doue all scored with composure for Paris Saint-Germain to seal a convincing penalty victory.
Now 14-time champions PSG, who faced last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now lifted this competition for the 12th time in the past 13 years.
