PSG has now won the prestigious cup on 14 separate times.
The Parisian giants required a stoppage-time equaliser followed by a successful penalty shootout to get past their arch-rivals in Kuwait and capture a fourth straight Trophee des Champions title.
The European champions seemed to be coasting towards a straightforward triumph in the showdown featuring the French league champions and the French Cup holders after the French winger opened the net in the opening stages.
Yet, Marseille struck two times in the closing moments to take a surprise lead. Initially, Mason Greenwood converted from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a remarkable twist of fortune, the Portuguese striker snatched a crucial equaliser in the final moments to send the match into a penalty shootout. The Parisian shot-stopper Chevalier then emerged as the key figure, stopping decisive kicks from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and the young talent all scored successfully for Paris Saint-Germain to seal a 4-1 shootout victory.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now lifted this competition for the twelfth time in the past thirteen years.
