The Parisian club has now claimed the season-opening trophy on fourteen separate occasions.
The Parisian giants required a dramatic equaliser followed by a successful penalty shootout to overcome Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders appeared to be sailing towards a straightforward win in the showdown featuring the Ligue 1 winners and the French Cup winners after Ousmane Dembele opened the scoring in the opening stages.
However, the southern French side struck twice in the closing moments to seize a shock advantage. First, Mason Greenwood converted from the penalty spot, before the defender inadvertently turned the ball into his own net for an own-goal.
In a breathtaking twist of fortune, Goncalo Ramos grabbed a crucial leveler in the dying moments to send the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, saving crucial attempts from O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all converted successfully for Paris Saint-Germain to complete a 4-1 shootout win.
Now 14-time champions PSG, who met last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now won this trophy for the 12th time in the last thirteen seasons.
