PSG has now claimed the season-opening cup on 14 different times.
Paris Saint-Germain required a dramatic leveler followed by a successful penalty shootout to overcome Marseille in Kuwait and secure a fourth straight French Super Cup victory.
The Champions League holders seemed to be sailing towards a comfortable triumph in the match featuring the Ligue 1 winners and the Coupe de France winners after the French winger found the net in the opening stages.
Yet, the southern French side struck twice in the closing moments to seize a shock lead. Initially, the English forward scored from the penalty spot, before the defender inadvertently directed the ball into his own net for an own-goal.
In a breathtaking turn of events, Goncalo Ramos grabbed a crucial leveler in the dying seconds to force the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, stopping crucial kicks from O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored successfully for Paris Saint-Germain to complete a 4-1 penalty win.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now lifted this trophy for the twelfth time in the past 13 years.
