The Parisian club has now secured the prestigious cup on 14 different occasions.
The Parisian giants needed a stoppage-time leveler followed by a successful spot-kick decider to overcome Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be sailing towards a straightforward triumph in the showdown featuring the French league winners and the Coupe de France winners after the French winger found the net early on.
Yet, the southern French side fired two times in the closing moments to take a shock lead. Initially, Mason Greenwood scored from the penalty spot, before the defender inadvertently turned the ball into his own net for an own goal.
In a remarkable turn of fortune, the Portuguese striker snatched a crucial equaliser in the dying moments to force the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, stopping decisive attempts from O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, the full-back, and the young talent all scored with composure for PSG to complete a convincing shootout victory.
Now 14-time winners PSG, who met 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.
