PSG has now claimed the season-opening trophy on fourteen different times.
Paris Saint-Germain required a dramatic leveler followed by a perfect penalty shootout to get past Marseille in the Gulf and secure a fourth straight Trophee des Champions victory.
The Champions League holders appeared to be sailing towards a straightforward win in the showdown between the Ligue 1 winners and the French Cup winners after the French winger found the scoring in the opening stages.
Yet, the southern French side struck twice late to take a surprise lead. Initially, Mason Greenwood converted from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a breathtaking turn of events, Goncalo Ramos grabbed a crucial equaliser in the final seconds to send the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, stopping crucial kicks from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored successfully for Paris Saint-Germain to seal a 4-1 penalty victory.
The record champions PSG, who faced last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now won this trophy for the 12th time in the last 13 years.
