PSG has now won the season-opening cup on fourteen separate occasions.
Paris Saint-Germain required a dramatic leveler followed by a successful penalty shootout to get past Marseille in the Gulf and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be coasting towards a straightforward triumph in the showdown between the Ligue 1 winners and the Coupe de France winners after Ousmane Dembele opened the net early on.
Yet, the southern French side fired two times late to seize a shock lead. Initially, Mason Greenwood scored from the penalty spot, before the defender inadvertently 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 seconds to force the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, stopping decisive kicks from O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all scored with composure for PSG to complete a convincing penalty win.
The record champions PSG, who met last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now won this competition for the twelfth time in the last 13 seasons.
