The Parisian club has now secured the prestigious trophy on fourteen different occasions.
Paris Saint-Germain 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 victory.
The European champions appeared to be coasting towards a comfortable win in the match featuring the Ligue 1 champions and the French Cup winners after Ousmane Dembele found the scoring early on.
Yet, Marseille fired two times in the closing moments to take a surprise advantage. First, Mason Greenwood converted from the spot-kick, before the defender inadvertently turned the ball into his own net for an own-goal.
In a breathtaking turn of fortune, the Portuguese striker snatched a vital equaliser in the dying moments to force the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, saving decisive attempts from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all converted with composure for PSG 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 won this competition for the twelfth time in the last thirteen years.
