The Parisian club has now won the season-opening cup on fourteen separate times.
The Parisian giants required a dramatic leveler followed by a perfect spot-kick decider to overcome their arch-rivals in Kuwait and secure a fourth straight French Super Cup victory.
The Champions League holders appeared to be sailing towards a comfortable win in the match featuring the Ligue 1 champions and the French Cup winners after the French winger opened the scoring early on.
Yet, Marseille struck twice in the closing moments to take a surprise advantage. First, Mason Greenwood converted from the penalty spot, before the defender inadvertently directed the ball into his own net for an own goal.
In a breathtaking twist of events, the Portuguese striker snatched a vital leveler in the final seconds to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, stopping decisive kicks from Matt O'Riley and Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and the young talent all scored successfully for PSG to complete a 4-1 penalty victory.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now lifted this competition for the twelfth time in the past thirteen seasons.
