PSG has now won the season-opening trophy on 14 separate times.
The Parisian giants required a stoppage-time equaliser followed by a successful spot-kick decider to get past Marseille in Kuwait and secure a fourth straight Trophee des Champions title.
The Champions League holders appeared to be coasting towards a straightforward win in the match featuring the Ligue 1 champions and the French Cup holders after the French winger found the net in the opening stages.
Yet, Marseille fired two times in the closing moments to seize a shock advantage. First, the English forward scored from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a remarkable turn of events, Goncalo Ramos grabbed a crucial equaliser in the final moments to force the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, saving crucial kicks from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all scored successfully for Paris Saint-Germain to seal a 4-1 penalty win.
The record winners PSG, who faced last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now won this trophy for the twelfth time in the last 13 years.
