The Parisian club has now won the season-opening cup on fourteen separate occasions.
The Parisian giants required a dramatic leveler followed by a perfect spot-kick decider 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 match between the Ligue 1 champions and the Coupe de France holders after the French winger opened the net in the opening stages.
However, the southern French side fired twice in the closing moments to take a surprise lead. First, the English forward scored from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a breathtaking twist of events, the Portuguese striker snatched a vital equaliser in the final moments to force the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, stopping decisive kicks from O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, the full-back, and the young talent all converted successfully for PSG to seal a 4-1 penalty victory.
Now 14-time winners PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after achieving a domestic double, have now won this competition for the twelfth time in the last thirteen years.
