The Parisian club has now claimed the prestigious cup on fourteen separate occasions.
The Parisian giants needed a stoppage-time equaliser followed by a successful spot-kick decider to get past Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions victory.
The European champions seemed to be sailing towards a straightforward triumph in the match between the French league champions and the French Cup holders after the French winger found the scoring early on.
Yet, Marseille struck twice late to seize a shock lead. First, Mason Greenwood scored 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 dying seconds to force the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, saving decisive kicks from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all converted with composure for Paris Saint-Germain to complete a 4-1 penalty victory.
Now 14-time champions PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now lifted this competition for the twelfth time in the past thirteen seasons.
