PSG has now won the season-opening cup on 14 separate times.
Paris Saint-Germain needed a stoppage-time equaliser followed by a perfect spot-kick decider to get past Marseille in the Gulf and capture a record-extending fourth consecutive French Super Cup title.
The European champions seemed to be coasting towards a comfortable win in the match between the Ligue 1 winners and the Coupe de France winners after Ousmane Dembele found the scoring early on.
Yet, the southern French side fired two times in the closing moments to seize a surprise lead. First, the English forward scored from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a remarkable twist of fortune, the Portuguese striker grabbed a crucial leveler in the final moments to force the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping crucial attempts from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted successfully for PSG to seal a convincing penalty win.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now lifted this trophy for the 12th time in the last thirteen years.
