The Parisian club has now claimed the season-opening trophy on fourteen different times.
The Parisian giants required a stoppage-time leveler followed by a successful penalty shootout to get past Marseille in Kuwait and secure a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders appeared to be coasting towards a straightforward win in the showdown featuring the French league champions and the Coupe de France winners after the French winger opened the net early on.
However, Marseille fired two times in the closing moments to take a shock lead. First, Mason Greenwood converted from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own goal.
In a remarkable turn of fortune, the Portuguese striker snatched a crucial leveler in the dying moments to force the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, saving crucial kicks from O'Riley and Traore.
In the shootout, Ramos, the midfielder, the full-back, and Desire Doue all scored with composure for Paris Saint-Germain to complete a convincing penalty win.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after completing a domestic double, have now lifted this competition for the 12th time in the last thirteen years.
