PSG has now won the season-opening trophy on 14 separate occasions.
Paris Saint-Germain required a stoppage-time equaliser followed by a successful spot-kick decider to overcome Marseille in the Gulf and capture a fourth straight Trophee des Champions victory.
The European champions appeared to be coasting towards a comfortable win in the match featuring the French league champions and the Coupe de France holders after Ousmane Dembele found the net in the opening stages.
Yet, Marseille struck two times in the closing moments to seize a shock lead. First, Mason Greenwood scored from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a breathtaking turn of events, the Portuguese striker grabbed a crucial leveler in the dying moments to send the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, stopping decisive attempts from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and the young talent all scored with composure for Paris Saint-Germain to seal a 4-1 penalty win.
The record champions PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now lifted this trophy for the twelfth time in the past 13 years.
