The Parisian club has now claimed the season-opening trophy on fourteen different occasions.
Paris Saint-Germain required a stoppage-time leveler followed by a perfect penalty shootout to overcome their arch-rivals in Kuwait and secure a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders appeared to be coasting towards a straightforward win in the showdown between the Ligue 1 champions and the Coupe de France winners after Ousmane Dembele found the net in the opening stages.
Yet, Marseille struck twice in the closing moments to seize a shock lead. Initially, the English forward scored from the penalty spot, before the defender unfortunately turned the ball into his own net for an own-goal.
In a remarkable twist of fortune, Goncalo Ramos grabbed a vital equaliser in the dying moments to send the contest into a penalty shootout. PSG goalkeeper Chevalier then emerged as the hero, saving crucial kicks from O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored with composure for Paris Saint-Germain to complete a 4-1 penalty win.
The record winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now won this trophy for the twelfth time in the past thirteen years.
