The Parisian club has now secured the prestigious cup on 14 different times.
The Parisian giants needed a stoppage-time leveler followed by a successful penalty shootout to overcome Marseille in the Gulf and secure a fourth straight French Super Cup victory.
The Champions League holders seemed to be sailing towards a comfortable win in the showdown between the French league winners and the French Cup holders after Ousmane Dembele found the scoring early on.
However, the southern French side fired two times in the closing moments to seize a surprise lead. First, Mason Greenwood converted from the spot-kick, before the defender inadvertently directed the ball into his own net for an own goal.
In a breathtaking twist of events, the Portuguese striker snatched a crucial equaliser in the dying seconds to force the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, saving decisive kicks from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted successfully for PSG to complete a convincing penalty win.
The record champions PSG, who met last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now won this trophy for the 12th time in the last 13 seasons.
