PSG has now won the season-opening trophy on 14 different times.
Paris Saint-Germain needed a stoppage-time leveler followed by a successful spot-kick decider to get past Marseille in the Gulf and secure a record-extending fourth consecutive French Super Cup victory.
The Champions League holders seemed to be coasting towards a straightforward win in the showdown featuring the Ligue 1 champions and the French Cup winners after Ousmane Dembele found the net early on.
However, Marseille struck two times late to take a shock advantage. 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 remarkable twist of events, the Portuguese striker snatched a crucial equaliser in the final moments to send the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, stopping crucial attempts from O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored successfully for Paris Saint-Germain to complete a convincing shootout victory.
Now 14-time champions Paris Saint-Germain, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now won this trophy for the twelfth time in the past 13 years.
