The Parisian club has now secured the prestigious cup on fourteen different 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 appeared to be coasting towards a straightforward triumph in the showdown between the French league winners and the Coupe de France winners after Ousmane Dembele found the scoring early on.
Yet, Marseille struck twice late to seize a shock lead. Initially, Mason Greenwood converted from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a breathtaking turn of events, the Portuguese striker grabbed a vital leveler in the final moments to send the match into a deciding shootout. The Parisian shot-stopper Chevalier then emerged as the key figure, stopping crucial attempts from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored successfully for PSG to seal a 4-1 penalty victory.
Now 14-time champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now lifted this competition for the twelfth time in the past 13 seasons.
