PSG has now claimed the season-opening cup on 14 separate times.
The Parisian giants needed a stoppage-time equaliser followed by a successful spot-kick decider to overcome Marseille in Kuwait and secure a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders seemed to be coasting towards a comfortable win in the showdown featuring the French league champions and the Coupe de France holders after Ousmane Dembele found the scoring early on.
However, Marseille fired twice in the closing moments to seize a surprise lead. Initially, the English forward converted from the spot-kick, before the defender unfortunately directed the ball into his own net for an own-goal.
In a breathtaking twist of events, the Portuguese striker snatched a vital leveler in the final moments to send the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, stopping decisive attempts from Matt O'Riley and Traore.
From the spot, Ramos, Vitinha, the full-back, and Desire Doue all scored with composure for PSG to seal a convincing penalty victory.
Now 14-time champions PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now lifted this trophy for the 12th time in the past 13 years.
