The Parisian club has now secured the prestigious cup on fourteen different occasions.
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 fourth straight French Super Cup victory.
The European champions seemed to be coasting towards a comfortable triumph in the match between the French league winners and the French Cup holders after the French winger opened the scoring in the opening stages.
However, the southern French side fired twice in the closing moments to take a shock advantage. First, Mason Greenwood scored from the spot-kick, before the defender unfortunately directed the ball into his own net for an own-goal.
In a breathtaking turn of fortune, Goncalo Ramos grabbed a crucial equaliser in the final seconds to send the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, saving crucial attempts from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted successfully for Paris Saint-Germain to complete a 4-1 shootout victory.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now won this trophy for the 12th time in the past thirteen seasons.
