The Parisian club has now secured the season-opening trophy on fourteen different occasions.
Paris Saint-Germain required a stoppage-time equaliser followed by a perfect penalty shootout to overcome Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders seemed to be coasting towards a comfortable win in the showdown featuring the Ligue 1 champions and the Coupe de France holders after the French winger opened the net in the opening stages.
However, the southern French side struck twice in the closing moments to seize a shock advantage. First, Mason Greenwood converted from the penalty spot, before the defender inadvertently directed the ball into his own net for an own goal.
In a remarkable turn of fortune, the Portuguese striker grabbed a crucial equaliser in the final seconds to send the match into a deciding shootout. PSG goalkeeper Chevalier then emerged as the hero, saving decisive kicks from O'Riley and Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to complete a 4-1 shootout win.
Now 14-time winners PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now won this trophy for the twelfth time in the past thirteen seasons.
