The Parisian club has now won the season-opening cup on 14 separate times.
Paris Saint-Germain required a dramatic leveler followed by a perfect spot-kick decider to overcome Marseille in Kuwait and secure a record-extending fourth consecutive Trophee des Champions victory.
The European champions seemed to be coasting towards a comfortable win in the showdown featuring the Ligue 1 winners and the Coupe de France holders after Ousmane Dembele found the net early on.
However, Marseille struck twice in the closing moments to seize a surprise lead. First, Mason Greenwood scored from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a breathtaking twist of events, the Portuguese striker snatched a crucial leveler in the dying moments to send the match into a penalty shootout. PSG goalkeeper Chevalier then emerged as the key figure, saving crucial kicks from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, the full-back, and the young talent all converted with composure for PSG to seal a 4-1 shootout victory.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Olympique de Marseille after achieving a domestic double, have now won this competition for the 12th time in the last 13 seasons.
