The Parisian club has now claimed the season-opening trophy on fourteen different times.
Paris Saint-Germain required a dramatic leveler followed by a successful penalty shootout to overcome Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions victory.
The European champions seemed to be coasting towards a straightforward win in the showdown featuring the Ligue 1 champions and the Coupe de France holders after Ousmane Dembele opened the net early on.
Yet, Marseille fired two times in the closing moments to seize a shock advantage. Initially, Mason Greenwood converted from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a breathtaking twist of events, Goncalo Ramos snatched a crucial equaliser in the dying moments to send the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, stopping crucial attempts from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and the young talent all scored successfully for PSG to complete a 4-1 shootout victory.
The record winners PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now won this trophy for the 12th time in the last 13 years.
