The Parisian club has now won the season-opening cup on fourteen separate occasions.
Paris Saint-Germain required a stoppage-time equaliser followed by a successful spot-kick decider to overcome Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be coasting towards a comfortable triumph in the match featuring the Ligue 1 winners and the French Cup winners after the French winger found the scoring early on.
Yet, the southern French side struck twice in the closing moments to seize a surprise advantage. First, Mason Greenwood converted from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a remarkable twist of fortune, the Portuguese striker snatched a crucial equaliser in the dying moments to send the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, stopping crucial kicks from Matt O'Riley and Traore.
In the shootout, Ramos, the midfielder, the full-back, and the young talent all converted successfully for PSG to seal a 4-1 shootout victory.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now won this competition for the twelfth time in the past 13 years.
