The Parisian club has now secured the season-opening trophy on fourteen separate times.
The Parisian giants required a stoppage-time leveler followed by a perfect spot-kick decider to get past Marseille in the Gulf and secure a record-extending fourth consecutive French Super Cup title.
The European champions seemed to be sailing towards a straightforward triumph in the showdown featuring the Ligue 1 winners and the French Cup winners after the French winger found the net in the opening stages.
Yet, Marseille struck twice late to take a surprise lead. Initially, Mason Greenwood converted from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a remarkable twist of events, the Portuguese striker snatched a vital equaliser in the final seconds to force the contest into a penalty shootout. PSG goalkeeper Chevalier then emerged as the hero, saving crucial kicks from O'Riley and Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored successfully for PSG to seal a 4-1 shootout victory.
Now 14-time champions PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a domestic double, have now lifted this competition for the twelfth time in the last thirteen seasons.
