PSG has now secured the prestigious trophy on 14 separate occasions.
The Parisian giants needed a dramatic equaliser followed by a perfect spot-kick decider to overcome Marseille in Kuwait and capture a fourth straight French Super Cup title.
The European champions appeared to be coasting towards a straightforward win in the showdown featuring the French league winners and the Coupe de France winners after Ousmane Dembele found the scoring in the opening stages.
However, Marseille fired twice late to take a surprise lead. First, Mason Greenwood scored from the penalty spot, before the defender inadvertently directed the ball into his own net for an own-goal.
In a remarkable turn of events, the Portuguese striker snatched a crucial leveler in the final seconds to force the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, saving decisive kicks from O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored successfully for Paris Saint-Germain to complete a convincing shootout victory.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now lifted this competition for the twelfth time in the last thirteen seasons.
