The Parisian club has now claimed the prestigious cup on fourteen separate occasions.
The Parisian giants required a dramatic equaliser followed by a perfect spot-kick decider to get past Marseille in Kuwait and capture a fourth straight Trophee des Champions victory.
The Champions League holders appeared to be sailing towards a comfortable triumph in the showdown featuring the French league winners and the French Cup winners after Ousmane Dembele opened the net in the opening stages.
Yet, Marseille struck two times late to take a surprise advantage. Initially, Mason Greenwood converted from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a remarkable twist of events, Goncalo Ramos grabbed a vital leveler in the dying seconds to force the match into a penalty shootout. PSG goalkeeper Chevalier then emerged as the hero, stopping crucial kicks from Matt O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all scored successfully for PSG to complete a convincing 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.
