PSG has now won the prestigious cup on 14 separate times.
The Parisian giants needed a dramatic 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 comfortable win in the match between the Ligue 1 champions and the Coupe de France holders after Ousmane Dembele found the net early on.
Yet, Marseille struck two times in the closing moments to take a surprise lead. First, the English forward converted from the penalty spot, before the defender inadvertently directed the ball into his own net for an own-goal.
In a remarkable turn of events, Goncalo Ramos snatched a vital leveler in the final seconds to force the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping crucial kicks from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all scored successfully for PSG to seal a convincing shootout win.
Now 14-time champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now lifted this trophy for the twelfth time in the last thirteen years.
