PSG has now secured the prestigious trophy on 14 different occasions.
The Parisian giants required a dramatic leveler followed by a successful spot-kick decider to overcome Marseille in Kuwait and secure a record-extending fourth consecutive French Super Cup title.
The European champions seemed to be coasting towards a straightforward win in the showdown between the French league winners and the Coupe de France holders after the French winger found the net in the opening stages.
However, Marseille struck twice late to seize a shock advantage. First, the English forward converted from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a remarkable twist of fortune, Goncalo Ramos snatched a crucial equaliser in the final moments to send the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, stopping decisive kicks from O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted successfully for PSG to seal a 4-1 shootout win.
Now 14-time champions PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now won this competition for the twelfth time in the last thirteen years.
