The Parisian club has now won the prestigious trophy on fourteen separate occasions.
The Parisian giants needed a stoppage-time leveler followed by a successful penalty shootout to get past their arch-rivals in the Gulf and secure a record-extending fourth consecutive French Super Cup title.
The European champions seemed to be coasting towards a comfortable triumph in the match between the French league winners and the French Cup winners after the French winger found the scoring early on.
However, Marseille fired twice in the closing moments to seize a shock advantage. Initially, the English forward converted from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a breathtaking turn of fortune, Goncalo Ramos snatched a crucial leveler in the final moments to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, saving decisive attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and Desire Doue all scored successfully for Paris Saint-Germain to seal a convincing penalty victory.
Now 14-time winners 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 last thirteen seasons.
