The Parisian club has now secured the prestigious cup on 14 separate times.
Paris Saint-Germain required a stoppage-time leveler followed by a perfect penalty shootout to overcome Marseille in Kuwait and secure a record-extending fourth consecutive Trophee des Champions victory.
The European champions appeared to be sailing towards a straightforward win in the showdown featuring the Ligue 1 champions and the French Cup winners after Ousmane Dembele found the scoring in the opening stages.
Yet, Marseille fired two times late to seize a shock advantage. First, Mason Greenwood converted from the penalty spot, before the defender unfortunately directed the ball into his own net for an own goal.
In a breathtaking twist of events, the Portuguese striker snatched a crucial equaliser in the final moments to force the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping decisive attempts from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored successfully for PSG to seal a 4-1 penalty win.
The record winners PSG, who faced last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now won this trophy for the twelfth time in the past thirteen seasons.
