PSG has now secured the season-opening trophy on 14 separate times.
The Parisian giants needed a stoppage-time leveler followed by a perfect spot-kick decider 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 straightforward triumph in the showdown featuring the Ligue 1 winners and the French Cup winners after the French winger opened the scoring early on.
Yet, Marseille fired twice in the closing moments to seize a shock lead. First, Mason Greenwood converted from the spot-kick, before the defender unfortunately turned the ball into his own net for an own-goal.
In a remarkable twist of events, Goncalo Ramos grabbed a crucial leveler in the dying moments to send the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, stopping crucial attempts from O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and the young talent all scored successfully for Paris Saint-Germain to complete a convincing shootout win.
The record winners PSG, who faced last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now won this trophy for the 12th time in the last thirteen years.
