The Parisian club has now won the prestigious trophy on 14 separate occasions.
The Parisian giants required a stoppage-time leveler followed by a perfect penalty shootout to overcome Marseille in Kuwait and secure a fourth straight French Super Cup victory.
The Champions League holders seemed to be coasting towards a comfortable triumph in the match between the Ligue 1 winners and the Coupe de France winners after the French winger found the scoring in the opening stages.
However, Marseille fired twice late to take a shock advantage. 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 events, Goncalo Ramos grabbed a crucial leveler in the final moments to send the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving decisive attempts from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored successfully for Paris Saint-Germain to seal a 4-1 penalty victory.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Olympique de Marseille after achieving a league and cup double, have now won this competition for the twelfth time in the last 13 seasons.
