The Parisian club has now won the season-opening cup on fourteen different times.
Paris Saint-Germain required a dramatic equaliser followed by a perfect penalty shootout to get past Marseille in the Gulf and capture a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders appeared to be coasting towards a straightforward triumph in the showdown featuring the Ligue 1 champions and the Coupe de France holders after Ousmane Dembele opened the net in the opening stages.
Yet, the southern French side struck two times late to take a surprise advantage. Initially, Mason Greenwood scored from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own goal.
In a remarkable twist of events, the Portuguese striker snatched a vital equaliser in the dying seconds to send the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, stopping crucial kicks from O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, the full-back, and the young talent all scored with composure for PSG to seal a 4-1 shootout win.
Now 14-time champions PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now lifted this trophy for the 12th time in the last thirteen seasons.
