PSG has now claimed the season-opening cup on 14 separate 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 Champions League holders seemed to be coasting towards a straightforward win in the showdown between the French league champions and the Coupe de France holders after Ousmane Dembele opened the net in the opening stages.
Yet, the southern French side struck two times in the closing moments to seize a shock lead. Initially, the English forward scored from the spot-kick, before the defender unfortunately directed the ball into his own net for an own-goal.
In a breathtaking twist of fortune, the Portuguese striker snatched a crucial equaliser in the dying seconds to send the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, saving crucial attempts from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and the young talent all scored with composure for PSG to seal a convincing penalty victory.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now lifted this competition for the 12th time in the past thirteen seasons.
