The Parisian club has now secured the season-opening trophy on fourteen different occasions.
The Parisian giants required a stoppage-time leveler followed by a successful penalty shootout to get past their arch-rivals in Kuwait and capture a fourth straight French Super Cup title.
The Champions League holders appeared to be sailing towards a straightforward triumph in the showdown between the French league winners and the Coupe de France holders after Ousmane Dembele opened the scoring in the opening stages.
Yet, the southern French side fired two times late to take a shock advantage. Initially, Mason Greenwood converted from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos snatched a crucial equaliser in the final seconds to force the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, saving crucial attempts from Matt O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all scored with composure for PSG to seal a convincing shootout victory.
Now 14-time winners PSG, who met last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now won this competition for the twelfth time in the past 13 years.
