The Parisian club has now secured the season-opening cup on 14 different times.
The Parisian giants required a dramatic leveler followed by a perfect penalty shootout to get past Marseille in Kuwait and capture a record-extending fourth consecutive French Super Cup victory.
The Champions League holders appeared to be sailing towards a straightforward win in the showdown featuring the French league champions and the French Cup holders after Ousmane Dembele found the scoring early on.
Yet, Marseille struck two times late to seize a shock lead. Initially, the English forward 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 fortune, Goncalo Ramos grabbed a crucial leveler in the final moments to force the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, saving decisive attempts from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all scored with composure for PSG to complete a convincing penalty victory.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now lifted this competition for the twelfth time in the past 13 years.
