PSG has now claimed the season-opening trophy on fourteen separate occasions.
Paris Saint-Germain needed a stoppage-time leveler followed by a successful spot-kick decider to get past Marseille in the Gulf and capture a record-extending fourth consecutive French Super Cup title.
The European champions appeared to be coasting towards a straightforward win in the showdown featuring the French league champions and the French Cup winners after Ousmane Dembele found the scoring in the opening stages.
However, the southern French side fired two times in the closing moments to seize a surprise lead. Initially, the English forward scored from the spot-kick, before Willian Pacho inadvertently directed 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 moments to send the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, stopping crucial attempts from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted successfully for PSG to complete a convincing shootout win.
The record champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now won this trophy for the twelfth time in the past 13 seasons.
