The Parisian club has now won the season-opening cup on 14 separate times.
The Parisian giants needed a dramatic leveler followed by a successful penalty shootout to overcome Marseille in the Gulf and capture a fourth straight French Super Cup title.
The European champions seemed to be coasting towards a straightforward triumph in the match featuring the Ligue 1 winners and the French Cup winners after the French winger found the net in the opening stages.
However, Marseille struck two times in the closing moments to take a shock lead. Initially, the English forward converted from the penalty spot, before the defender unfortunately turned the ball into his own net for an own-goal.
In a remarkable turn of events, Goncalo Ramos grabbed a vital leveler in the final moments to force the match into a penalty shootout. PSG goalkeeper Chevalier then stood as the key figure, stopping crucial attempts from O'Riley and Traore.
In the shootout, Ramos, the midfielder, the full-back, and Desire Doue all scored with composure for Paris Saint-Germain to complete a 4-1 penalty victory.
Now 14-time champions PSG, who faced last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now lifted this competition for the 12th time in the past thirteen years.
