PSG has now secured the season-opening cup on fourteen separate times.
Paris Saint-Germain required a stoppage-time equaliser followed by a successful penalty shootout to overcome Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions victory.
The European champions seemed to be sailing towards a straightforward win in the showdown featuring the French league winners and the Coupe de France winners after Ousmane Dembele opened the scoring early on.
However, Marseille fired two times in the closing moments to seize a surprise advantage. First, Mason Greenwood converted from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a breathtaking twist of fortune, the Portuguese striker grabbed a crucial leveler in the dying moments to force the match into a penalty shootout. PSG goalkeeper Chevalier then stood as the key figure, saving decisive attempts from O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and the young talent all converted with composure for Paris Saint-Germain to seal a 4-1 penalty victory.
The record champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a league and cup double, have now lifted this trophy for the 12th time in the past 13 years.
