PSG has now secured the season-opening trophy on 14 separate occasions.
Paris Saint-Germain required a stoppage-time equaliser followed by a perfect penalty shootout to overcome Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders appeared to be sailing towards a comfortable triumph in the showdown featuring the French league winners and the Coupe de France winners after the French winger found the scoring early on.
Yet, the southern French side fired two times late to take a shock advantage. First, Mason Greenwood converted from the penalty spot, before the defender unfortunately turned the ball into his own net for an own-goal.
In a breathtaking turn of events, Goncalo Ramos snatched a crucial equaliser in the final seconds to send the match into a penalty shootout. PSG goalkeeper Chevalier then stood as the hero, stopping decisive attempts from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored with composure for PSG to seal a 4-1 penalty win.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now lifted this competition for the 12th time in the past 13 seasons.
