The Parisian club has now secured the season-opening cup on fourteen separate times.
The Parisian giants required a stoppage-time leveler followed by a perfect penalty shootout to get past their arch-rivals in Kuwait and capture a fourth straight French Super Cup title.
The Champions League holders seemed to be sailing towards a comfortable win in the showdown featuring the French league champions and the French Cup holders after Ousmane Dembele opened the net in the opening stages.
Yet, Marseille struck twice late to seize a surprise lead. Initially, Mason Greenwood scored from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a remarkable turn of events, the Portuguese striker grabbed a vital leveler in the dying moments to send the contest into a deciding shootout. PSG goalkeeper Chevalier then emerged as the key figure, saving crucial kicks from Matt O'Riley and Traore.
In the shootout, Ramos, Vitinha, the full-back, and Desire Doue all converted successfully for PSG to complete a convincing shootout win.
The record champions PSG, who met last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now won this trophy for the 12th time in the last 13 years.
