PSG has now secured the prestigious trophy on 14 separate times.
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 victory.
The European champions appeared to be coasting towards a comfortable triumph in the showdown featuring the French league champions and the French Cup holders after the French winger found the net in the opening stages.
However, the southern French side struck two times in the closing moments to seize a surprise lead. First, Mason Greenwood scored from the spot-kick, before the defender inadvertently turned the ball into his own net for an own goal.
In a remarkable twist of fortune, Goncalo Ramos snatched a vital leveler in the final moments to force the match into a deciding shootout. PSG goalkeeper Chevalier then stood as the key figure, saving crucial attempts from O'Riley and Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to complete a convincing penalty win.
Now 14-time winners PSG, who met last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now lifted this competition for the 12th time in the last thirteen seasons.
