The Parisian club has now won the season-opening cup on fourteen different occasions.
The Parisian giants needed a dramatic leveler followed by a perfect penalty shootout to overcome Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be sailing towards a straightforward win in the showdown featuring the Ligue 1 winners and the French Cup winners after Ousmane Dembele opened the scoring early on.
Yet, Marseille fired two times in the closing moments to seize a surprise lead. Initially, Mason Greenwood scored from the spot-kick, before the defender unfortunately directed the ball into his own net for an own goal.
In a remarkable turn of fortune, the Portuguese striker grabbed a vital leveler in the final seconds to send the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, stopping decisive kicks from O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to complete a convincing shootout win.
The record winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now won this competition for the 12th time in the last thirteen seasons.
