PSG has now secured the prestigious trophy on fourteen separate occasions.
The Parisian giants required a stoppage-time leveler followed by a perfect penalty shootout to overcome Marseille in the Gulf and secure a record-extending fourth consecutive French Super Cup title.
The European champions appeared to be coasting towards a comfortable triumph in the match between the French league champions and the Coupe de France holders after the French winger found the net early on.
However, the southern French side struck twice in the closing moments to take a shock lead. First, Mason Greenwood converted from the penalty spot, 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 crucial equaliser in the final moments to force the match into a deciding shootout. PSG goalkeeper Chevalier then emerged as the hero, stopping decisive kicks from O'Riley and Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and the young talent all converted with composure for PSG to complete a convincing shootout victory.
Now 14-time winners PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now lifted this trophy for the 12th time in the last 13 seasons.
