The Parisian club has now secured the prestigious cup on 14 different times.
Paris Saint-Germain needed a stoppage-time equaliser followed by a successful penalty shootout to get past Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders seemed to be sailing towards a straightforward win in the showdown between the Ligue 1 champions and the Coupe de France holders after the French winger opened the scoring in the opening stages.
Yet, the southern French side struck two times in the closing moments to seize a surprise lead. First, the English forward converted from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a breathtaking twist of fortune, the Portuguese striker snatched a crucial leveler in the dying moments to force the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, saving decisive kicks from Matt O'Riley and Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and the young talent all converted with composure for Paris Saint-Germain to seal a 4-1 shootout victory.
Now 14-time champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now won this competition for the twelfth time in the last thirteen seasons.
