The Parisian club has now won the season-opening trophy on fourteen different times.
The Parisian giants needed a stoppage-time leveler followed by a successful spot-kick decider to get past Marseille in the Gulf and secure a fourth straight Trophee des Champions title.
The Champions League holders appeared to be coasting towards a comfortable win in the showdown between the Ligue 1 winners and the Coupe de France holders after the French winger found the scoring in the opening stages.
Yet, the southern French side struck twice late to seize a surprise advantage. Initially, Mason Greenwood scored from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos snatched a crucial equaliser in the dying seconds to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving crucial kicks from O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, the full-back, and Desire Doue all scored successfully for PSG to complete a 4-1 penalty win.
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 past 13 seasons.
