The Parisian club has now claimed the season-opening cup on 14 different times.
The Parisian giants needed a stoppage-time leveler followed by a successful penalty shootout to get past Marseille in Kuwait and capture a fourth straight Trophee des Champions victory.
The European champions seemed to be sailing towards a comfortable win in the showdown featuring the French league champions and the French Cup winners after Ousmane Dembele found the net early on.
However, Marseille fired two times in the closing moments to seize a shock lead. Initially, Mason Greenwood scored from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own goal.
In a breathtaking twist of fortune, Goncalo Ramos grabbed a vital equaliser in the final seconds to send the match into a penalty shootout. The Parisian shot-stopper Chevalier then emerged as the hero, saving crucial kicks from Matt O'Riley and Traore.
In the shootout, Ramos, the midfielder, the full-back, and Desire Doue all converted successfully for PSG to complete a 4-1 penalty victory.
The record champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now lifted this competition for the twelfth time in the past 13 seasons.
