The Parisian club has now claimed the prestigious cup on fourteen separate occasions.
The Parisian giants needed a dramatic leveler followed by a perfect penalty shootout to get past their arch-rivals in the Gulf and secure a fourth straight French Super Cup title.
The Champions League holders seemed to be coasting towards a comfortable win in the showdown between the Ligue 1 champions and the Coupe de France holders after Ousmane Dembele found the scoring in the opening stages.
Yet, the southern French side struck two times late to seize a shock advantage. First, Mason Greenwood converted from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a remarkable twist of events, Goncalo Ramos grabbed a vital leveler in the dying moments to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving crucial attempts from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted successfully for PSG to complete a 4-1 penalty victory.
The record champions PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now lifted this trophy for the twelfth time in the last 13 seasons.
