The Parisian club has now secured the season-opening trophy on fourteen separate occasions.
The Parisian giants required a dramatic equaliser followed by a perfect spot-kick decider to get past Marseille in Kuwait and secure a fourth straight French Super Cup title.
The European champions seemed to be sailing towards a straightforward win in the showdown between the French league winners and the Coupe de France winners after Ousmane Dembele opened the scoring in the opening stages.
Yet, Marseille fired two times late to seize a surprise advantage. Initially, Mason Greenwood converted from the penalty spot, before the defender unfortunately directed the ball into his own net for an own goal.
In a breathtaking twist of events, the Portuguese striker grabbed a crucial leveler in the final seconds to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, saving crucial attempts from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and Desire Doue all converted with composure for Paris Saint-Germain to seal a convincing shootout win.
Now 14-time champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now won this trophy for the twelfth time in the last thirteen years.
