PSG has now claimed the prestigious cup on fourteen different occasions.
Paris Saint-Germain required a dramatic leveler followed by a successful spot-kick decider to get past their arch-rivals in the Gulf and capture a fourth straight Trophee des Champions victory.
The European champions seemed to be sailing towards a straightforward win in the match between the French league champions and the Coupe de France winners after Ousmane Dembele found the scoring early on.
Yet, Marseille fired twice late to take a surprise lead. Initially, the English forward scored from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own goal.
In a breathtaking twist of events, the Portuguese striker grabbed a vital leveler in the dying moments to force the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, stopping crucial kicks from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to seal a 4-1 shootout victory.
The record winners PSG, who faced last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now won this trophy for the twelfth time in the past 13 seasons.
