The Parisian club has now secured the season-opening trophy on fourteen separate occasions.
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 title.
The European champions appeared to be coasting towards a comfortable triumph in the showdown featuring the Ligue 1 champions and the French Cup holders after the French winger found the scoring in the opening stages.
Yet, the southern French side struck two times in the closing moments to take a shock lead. Initially, Mason Greenwood converted from the spot-kick, before the defender unfortunately directed the ball into his own net for an own-goal.
In a breathtaking turn of fortune, the Portuguese striker grabbed a crucial equaliser in the final seconds to send the match into a penalty shootout. PSG goalkeeper Chevalier then stood as the key figure, saving crucial attempts from O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted with composure for Paris Saint-Germain to complete a convincing shootout victory.
Now 14-time winners PSG, who met 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 13 seasons.
