The Parisian club has now won the prestigious cup on 14 separate times.
Paris Saint-Germain needed a dramatic leveler followed by a perfect spot-kick decider to get past Marseille in Kuwait and capture a record-extending fourth consecutive French Super Cup victory.
The European champions appeared to be coasting towards a straightforward triumph in the match featuring the French league winners and the French Cup holders after Ousmane Dembele found the scoring in the opening stages.
Yet, the southern French side struck two times in the closing moments to seize a shock lead. First, the English forward scored from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a breathtaking twist of events, the Portuguese striker grabbed a crucial equaliser in the final moments to force the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping decisive kicks from O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored successfully for PSG to complete a 4-1 penalty win.
Now 14-time champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a domestic double, have now lifted this competition for the twelfth time in the last thirteen seasons.
