The Parisian club has now won the prestigious cup on fourteen separate times.
The Parisian giants required a stoppage-time leveler followed by a successful penalty shootout to get past Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions victory.
The European champions seemed to be coasting towards a comfortable triumph in the showdown featuring the French league winners and the Coupe de France holders after the French winger opened the scoring early on.
Yet, Marseille fired twice in the closing moments to seize a shock lead. Initially, Mason Greenwood scored 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, Goncalo Ramos grabbed a vital leveler in the final seconds to force the match into a penalty shootout. PSG goalkeeper Chevalier then emerged as the key figure, stopping crucial attempts from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all scored successfully for Paris Saint-Germain to complete a convincing shootout win.
The record winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now lifted this competition for the twelfth time in the last thirteen years.
