The Parisian club has now secured the prestigious cup on fourteen separate times.
The Parisian giants needed a stoppage-time leveler followed by a successful spot-kick decider to overcome their arch-rivals in Kuwait and secure a record-extending fourth consecutive French Super Cup title.
The European champions seemed to be coasting towards a straightforward triumph in the showdown featuring the French league champions and the French Cup winners after the French winger opened the scoring in the opening stages.
Yet, the southern French side struck two times in the closing moments to seize a shock advantage. First, the English forward scored from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own goal.
In a breathtaking turn of events, the Portuguese striker grabbed a crucial leveler in the final seconds to send the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, saving crucial kicks from O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted with composure for PSG to complete a 4-1 shootout win.
The record champions PSG, who faced last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now lifted this trophy for the twelfth time in the past thirteen seasons.
