The Parisian club has now claimed the season-opening trophy on fourteen separate times.
Paris Saint-Germain required a stoppage-time leveler followed by a successful penalty shootout to overcome Marseille in Kuwait and secure a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders seemed to be coasting towards a straightforward triumph in the match between the Ligue 1 winners and the Coupe de France holders after Ousmane Dembele found the scoring early on.
Yet, the southern French side struck two times late to take a surprise advantage. Initially, Mason Greenwood scored from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own goal.
In a breathtaking turn of events, the Portuguese striker grabbed a vital leveler in the dying moments to force the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, stopping crucial attempts from O'Riley and Hamed 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 penalty win.
Now 14-time champions Paris Saint-Germain, 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 past 13 seasons.
