The Parisian club has now won the season-opening cup on 14 separate occasions.
The Parisian giants needed a stoppage-time leveler followed by a perfect penalty shootout to overcome their arch-rivals in the Gulf and capture a fourth straight French Super Cup victory.
The European champions seemed to be coasting towards a comfortable win in the showdown between the French league winners and the French Cup winners after the French winger opened the scoring in the opening stages.
Yet, the southern French side fired two times late to seize a shock lead. First, the English forward scored from the spot-kick, before the defender inadvertently turned the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos snatched a vital leveler 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 Matt O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and the young talent all converted with composure for Paris Saint-Germain to complete a convincing penalty victory.
Now 14-time champions PSG, who met last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now won this trophy for the 12th time in the past 13 years.
