The Parisian club has now secured the season-opening cup on fourteen different times.
Paris Saint-Germain required a dramatic leveler followed by a perfect spot-kick decider to get past Marseille in the Gulf and secure a record-extending fourth consecutive French Super Cup title.
The European champions appeared to be coasting towards a straightforward triumph in the match featuring the French league winners and the French Cup winners after the French winger found the scoring early on.
Yet, the southern French side fired twice late to take a shock lead. First, the English forward scored from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a breathtaking twist of events, the Portuguese striker snatched a crucial equaliser in the final seconds to force the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, stopping crucial attempts from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all converted with composure for Paris Saint-Germain to seal a 4-1 shootout victory.
Now 14-time champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now lifted this competition for the twelfth time in the last 13 seasons.
