The Parisian club has now secured the season-opening cup on fourteen different times.
Paris Saint-Germain needed a stoppage-time leveler followed by a successful penalty shootout to get past their arch-rivals in Kuwait and secure a fourth straight French Super Cup title.
The Champions League holders appeared to be coasting towards a straightforward win in the match between the French league champions and the French Cup winners after Ousmane Dembele found the scoring in the opening stages.
Yet, the southern French side fired twice in the closing moments to seize a shock lead. First, Mason Greenwood converted from the spot-kick, before the defender unfortunately turned the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos snatched a crucial leveler in the dying seconds to send the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, saving decisive attempts from O'Riley and Traore.
In the shootout, Ramos, the midfielder, the full-back, and Desire Doue all scored successfully for PSG to complete a 4-1 penalty win.
Now 14-time winners Paris Saint-Germain, 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 thirteen seasons.
