PSG has now secured the season-opening trophy on 14 different occasions.
Paris Saint-Germain required a stoppage-time equaliser followed by a successful spot-kick decider to get past Marseille in the Gulf and capture a record-extending fourth consecutive Trophee des Champions victory.
The European champions appeared to be coasting towards a comfortable triumph in the match between the Ligue 1 champions and the Coupe de France holders after the French winger found the net early on.
Yet, Marseille fired two times in the closing moments to seize a shock lead. First, Mason Greenwood scored from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a breathtaking twist of events, Goncalo Ramos grabbed a crucial leveler in the final seconds to force the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, stopping crucial attempts from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, the full-back, and Desire Doue all converted with composure for PSG to seal a 4-1 penalty win.
The record winners 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.
