PSG has now secured the season-opening cup on fourteen separate occasions.
Paris Saint-Germain required a dramatic leveler followed by a successful spot-kick decider to overcome their arch-rivals in the Gulf and secure a fourth straight French Super Cup title.
The European champions appeared to be sailing towards a comfortable triumph in the match featuring the French league champions and the French Cup holders after Ousmane Dembele found the scoring early on.
Yet, the southern French side fired two times late to seize a shock advantage. First, Mason Greenwood scored from the spot-kick, before the defender inadvertently turned the ball into his own net for an own goal.
In a remarkable turn of fortune, Goncalo Ramos snatched a crucial equaliser in the dying moments to force the match into a penalty shootout. The Parisian shot-stopper Chevalier then stood as the key figure, saving crucial attempts from O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all scored with composure for PSG to complete a 4-1 penalty win.
The record champions PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a league and cup double, have now lifted this trophy for the 12th time in the past 13 seasons.
