The Parisian club has now claimed the prestigious cup on fourteen different occasions.
Paris Saint-Germain needed a stoppage-time equaliser followed by a perfect spot-kick decider to overcome Marseille in Kuwait and secure a fourth straight Trophee des Champions victory.
The Champions League holders seemed to be sailing towards a straightforward triumph in the showdown between the Ligue 1 winners and the Coupe de France holders after Ousmane Dembele found the net in the opening stages.
However, Marseille fired twice in the closing moments to seize a shock advantage. Initially, Mason Greenwood scored from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a breathtaking turn of events, the Portuguese striker grabbed a vital leveler in the dying moments to force the match into a penalty shootout. PSG goalkeeper Chevalier then emerged as the hero, stopping crucial attempts from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and the young talent all scored successfully for Paris Saint-Germain to complete a 4-1 shootout win.
The record winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a domestic double, have now lifted this competition for the 12th time in the last 13 seasons.
