PSG has now secured the season-opening trophy on fourteen different occasions.
The Parisian giants required a stoppage-time equaliser followed by a successful penalty shootout to overcome their arch-rivals in the Gulf and capture a record-extending fourth consecutive French Super Cup victory.
The Champions League holders seemed to be coasting towards a straightforward win in the match between the Ligue 1 champions and the French Cup holders after the French winger opened the net early on.
However, the southern French side fired two times late to seize a shock lead. Initially, the English forward scored from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own goal.
In a breathtaking turn of events, Goncalo Ramos snatched a crucial leveler in the final moments to send the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, saving decisive attempts from O'Riley and Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and the young talent all converted with composure for PSG to complete a convincing shootout win.
The record champions PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now won this trophy for the 12th time in the last 13 seasons.
