The Parisian club has now won the prestigious cup on fourteen separate times.
The Parisian giants required a stoppage-time leveler followed by a successful penalty shootout to overcome Marseille in Kuwait and secure a record-extending fourth consecutive French Super Cup victory.
The European champions appeared to be coasting towards a comfortable win in the match featuring the French league champions and the French Cup winners after the French winger found the scoring early on.
Yet, the southern French side fired two times late to seize a shock lead. First, Mason Greenwood scored from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a remarkable turn of events, the Portuguese striker grabbed a crucial equaliser in the final seconds to send the contest into a penalty shootout. The Parisian shot-stopper Chevalier then stood as the hero, stopping decisive kicks from O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, the full-back, and Desire Doue all converted with composure for Paris Saint-Germain to complete a 4-1 penalty win.
Now 14-time champions PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after achieving a league and cup double, have now lifted this competition for the twelfth time in the last thirteen years.
