PSG has now secured the prestigious trophy on fourteen separate occasions.
The Parisian giants needed a stoppage-time leveler followed by a successful penalty shootout to overcome Marseille in Kuwait and secure a fourth straight French Super Cup victory.
The European champions appeared to be coasting towards a straightforward triumph in the showdown featuring the Ligue 1 champions and the French Cup winners after Ousmane Dembele found the scoring in the opening stages.
Yet, the southern French side fired two times late to seize a shock advantage. First, Mason Greenwood scored from the spot-kick, before the defender unfortunately turned the ball into his own net for an own goal.
In a breathtaking twist of fortune, Goncalo Ramos grabbed a crucial equaliser in the final moments to force the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving decisive kicks from O'Riley and Traore.
From the spot, Ramos, the midfielder, the full-back, and the young talent all scored successfully for PSG to complete a 4-1 shootout victory.
Now 14-time champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now lifted this competition for the twelfth time in the past thirteen years.
