The Parisian club has now secured the season-opening cup on 14 separate occasions.
The Parisian giants needed a dramatic leveler 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 appeared to be sailing towards a comfortable win in the match featuring the French league winners and the Coupe de France winners after Ousmane Dembele found the scoring in the opening stages.
Yet, Marseille fired two times late to take a shock lead. First, the English forward converted from the spot-kick, before the defender unfortunately directed the ball into his own net for an own-goal.
In a remarkable turn of events, Goncalo Ramos grabbed a crucial equaliser in the dying seconds to send the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, stopping crucial kicks from O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all scored with composure for PSG to seal a convincing shootout win.
Now 14-time champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now won this competition for the 12th time in the last thirteen years.
