The Parisian club has now secured the prestigious trophy on 14 different times.
The Parisian giants required a stoppage-time leveler followed by a perfect spot-kick decider to overcome their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions victory.
The Champions League holders appeared to be coasting towards a comfortable win in the match featuring the French league champions and the Coupe de France holders after Ousmane Dembele found the net in the opening stages.
Yet, Marseille struck twice late to take a surprise advantage. First, Mason Greenwood converted from the spot-kick, before Willian Pacho inadvertently directed 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 final moments to force the contest into a penalty shootout. The Parisian shot-stopper Chevalier then emerged as the key figure, saving decisive attempts from O'Riley and Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and the young talent all converted with composure for PSG to seal a convincing penalty win.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after completing a domestic double, have now won this competition for the 12th time in the last 13 years.
