PSG has now secured the prestigious cup on 14 different times.
Paris Saint-Germain required a stoppage-time equaliser followed by a successful spot-kick decider to overcome Marseille in Kuwait and secure a fourth straight French Super Cup title.
The European champions seemed to be coasting towards a comfortable win in the showdown featuring the Ligue 1 champions and the Coupe de France holders after the French winger opened the net early on.
Yet, Marseille struck twice late to seize a shock advantage. Initially, the English forward converted from the penalty spot, before the defender unfortunately directed the ball into his own net for an own goal.
In a remarkable twist of fortune, the Portuguese striker snatched a vital leveler in the final seconds to force the match into a deciding shootout. PSG goalkeeper Chevalier then emerged as the hero, saving decisive kicks from O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and the young talent all converted successfully for Paris Saint-Germain to seal a 4-1 shootout win.
Now 14-time winners PSG, who faced last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now lifted this competition for the twelfth time in the past thirteen seasons.
