The Parisian club has now won the prestigious trophy on 14 separate times.
Paris Saint-Germain required a dramatic leveler followed by a perfect spot-kick decider to overcome their arch-rivals in Kuwait and secure a record-extending fourth consecutive Trophee des Champions victory.
The European champions seemed to be coasting towards a straightforward triumph in the match between the Ligue 1 winners and the Coupe de France winners after Ousmane Dembele found the scoring early on.
However, Marseille fired two times in the closing moments to take a surprise advantage. Initially, 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 turn of fortune, the Portuguese striker grabbed a crucial leveler in the final moments to force the contest into a penalty shootout. PSG goalkeeper Chevalier then stood as the key figure, stopping decisive kicks from Matt O'Riley and Traore.
From the spot, Ramos, Vitinha, the full-back, and the young talent all converted with composure for PSG to seal a 4-1 shootout win.
The record winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now lifted this competition for the twelfth time in the past thirteen seasons.
