PSG has now secured the prestigious trophy on 14 different occasions.
Paris Saint-Germain needed a dramatic leveler followed by a perfect penalty shootout to get past Marseille in Kuwait and capture a fourth straight Trophee des Champions victory.
The Champions League holders seemed to be coasting towards a comfortable triumph in the showdown between the French league winners and the French Cup winners after Ousmane Dembele found the scoring early on.
However, Marseille struck twice late to take a shock advantage. First, Mason Greenwood converted from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a breathtaking turn of events, Goncalo Ramos grabbed a crucial leveler in the final moments to force the contest into a penalty shootout. PSG goalkeeper Chevalier then stood as the key figure, stopping crucial attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all scored successfully for PSG to seal a 4-1 penalty win.
The record winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now won this trophy for the 12th time in the last 13 seasons.
