The Parisian club has now secured the prestigious trophy on 14 different times.
Paris Saint-Germain needed a stoppage-time leveler followed by a successful spot-kick decider to overcome their arch-rivals in Kuwait and capture a fourth straight Trophee des Champions title.
The Champions League holders seemed to be sailing towards a comfortable win in the match between the French league champions and the Coupe de France holders after Ousmane Dembele found the net early on.
Yet, the southern French side fired twice in the closing moments to take a shock 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 breathtaking twist of events, Goncalo Ramos grabbed a vital leveler in the final moments to send the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, stopping crucial kicks from O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored successfully for Paris Saint-Germain to complete a 4-1 shootout win.
The record winners PSG, who faced last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now won this trophy for the twelfth time in the last thirteen seasons.
