The Parisian club has now secured the prestigious trophy on fourteen different occasions.
The Parisian giants needed a stoppage-time leveler followed by a perfect spot-kick decider to get past Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be coasting towards a straightforward win in the match between the French league champions and the Coupe de France winners after Ousmane Dembele found the scoring early on.
Yet, Marseille struck two times late to seize a surprise advantage. Initially, Mason Greenwood scored from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own goal.
In a remarkable twist of events, the Portuguese striker snatched a vital leveler in the final moments to force the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, stopping decisive kicks from O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and the young talent all scored successfully for PSG to seal a convincing shootout win.
The record champions PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now lifted this trophy for the 12th time in the last thirteen years.
