The Parisian club has now secured the season-opening trophy on 14 separate occasions.
The Parisian giants required a stoppage-time leveler followed by a successful penalty shootout to get past their arch-rivals in Kuwait and secure a record-extending fourth consecutive French Super Cup victory.
The European champions appeared to be sailing towards a comfortable win in the match between the French league winners and the French Cup holders after Ousmane Dembele opened the net in the opening stages.
Yet, the southern French side fired twice late to take a shock advantage. First, the English forward converted from the penalty spot, before the defender unfortunately turned the ball into his own net for an own goal.
In a breathtaking twist of events, Goncalo Ramos grabbed a crucial equaliser in the final moments to send the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, saving decisive attempts from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and the young talent all converted successfully for Paris Saint-Germain to complete a convincing shootout victory.
The record champions Paris Saint-Germain, 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 last thirteen seasons.
