PSG has now secured the season-opening cup on fourteen different times.
The Parisian giants needed a dramatic leveler followed by a successful spot-kick decider to overcome Marseille in the Gulf and capture a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders appeared to be sailing towards a straightforward win in the showdown featuring the French league winners and the Coupe de France winners after the French winger opened the net in the opening stages.
Yet, the southern French side struck two times late to take a surprise lead. First, the English forward scored from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a remarkable twist of events, Goncalo Ramos snatched a crucial equaliser in the final moments to send the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, stopping decisive attempts from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all scored with composure for Paris Saint-Germain to seal a 4-1 penalty victory.
Now 14-time champions PSG, who faced last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now lifted this trophy for the 12th time in the last thirteen years.
