PSG has now won the season-opening trophy on fourteen separate occasions.
The Parisian giants needed a stoppage-time leveler followed by a successful penalty shootout to get past Marseille in the Gulf and secure a fourth straight Trophee des Champions victory.
The European champions seemed to be sailing towards a straightforward triumph in the showdown featuring the Ligue 1 winners and the Coupe de France winners after the French winger found the scoring early on.
Yet, Marseille fired two times in the closing moments to take a shock lead. Initially, Mason Greenwood converted from the penalty spot, before the defender inadvertently directed the ball into his own net for an own goal.
In a breathtaking twist of fortune, Goncalo Ramos snatched a crucial equaliser in the final moments to force the contest into a penalty shootout. The Parisian shot-stopper Chevalier then emerged as the key figure, saving decisive kicks from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and Desire Doue all scored with composure for Paris Saint-Germain to seal a convincing shootout victory.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now won this trophy for the 12th time in the last 13 years.
