The Parisian club has now claimed the season-opening cup on 14 different times.
Paris Saint-Germain needed a dramatic leveler followed by a successful spot-kick decider to overcome Marseille in Kuwait and capture a fourth straight Trophee des Champions title.
The Champions League holders appeared to be sailing towards a straightforward triumph in the match between the French league champions and the Coupe de France holders after Ousmane Dembele opened the scoring early on.
However, the southern French side struck twice in the closing moments to seize a shock lead. First, the English forward converted from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a breathtaking twist of fortune, the Portuguese striker snatched a crucial equaliser in the dying seconds to send the contest into a deciding shootout. The Parisian shot-stopper Chevalier then emerged as the key figure, saving decisive kicks from O'Riley and Traore.
In the shootout, Ramos, the midfielder, the full-back, and the young talent all scored with composure for PSG to complete a convincing penalty win.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now lifted this trophy for the 12th time in the past 13 years.
