PSG has now claimed the prestigious cup on fourteen separate occasions.
Paris Saint-Germain required a dramatic leveler followed by a successful spot-kick decider to overcome Marseille in Kuwait and capture a fourth straight Trophee des Champions title.
The Champions League holders appeared to be sailing towards a straightforward triumph in the showdown between the Ligue 1 champions and the Coupe de France holders after Ousmane Dembele found the scoring early on.
Yet, the southern French side fired two times in the closing moments to take a surprise advantage. Initially, Mason Greenwood scored from the spot-kick, before the defender unfortunately turned the ball into his own net for an own-goal.
In a remarkable twist of events, Goncalo Ramos snatched a crucial equaliser in the final moments to force the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, saving crucial attempts 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 complete a convincing shootout victory.
The record champions PSG, who met last season's Ligue 1 runners-up Marseille after completing a domestic double, have now won this trophy for the twelfth time in the last thirteen years.
