The Parisian club has now secured the prestigious trophy on fourteen different occasions.
The Parisian giants required a dramatic equaliser followed by a perfect spot-kick decider to get past their arch-rivals in Kuwait and capture a record-extending fourth consecutive Trophee des Champions victory.
The European champions appeared to be sailing towards a comfortable win in the showdown between the French league winners and the Coupe de France winners after Ousmane Dembele opened the scoring in the opening stages.
Yet, Marseille struck two times late to take a surprise lead. First, the English forward scored from the penalty spot, before the defender inadvertently directed the ball into his own net for an own goal.
In a breathtaking turn of fortune, the Portuguese striker snatched a crucial leveler in the final moments to force the contest into a penalty shootout. PSG goalkeeper Chevalier then stood as the hero, saving crucial kicks from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and the young talent all scored with composure for PSG to complete a convincing shootout win.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after completing a domestic double, have now won this trophy for the twelfth time in the past thirteen seasons.
