The Parisian club has now won the season-opening cup on fourteen separate times.
The Parisian giants required a stoppage-time equaliser followed by a perfect penalty shootout to get past their arch-rivals in Kuwait and secure a fourth straight French Super Cup victory.
The Champions League holders appeared to be coasting towards a comfortable win in the showdown between the French league champions and the French Cup winners after the French winger opened the net early on.
Yet, Marseille struck twice late to seize a surprise lead. Initially, Mason Greenwood scored from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a remarkable turn of events, the Portuguese striker grabbed a crucial leveler in the dying moments to send the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, stopping crucial kicks from O'Riley and Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored successfully for Paris Saint-Germain to complete a 4-1 shootout victory.
Now 14-time champions PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now won this trophy for the twelfth time in the past thirteen years.
