PSG has now secured the prestigious cup on fourteen separate occasions.
Paris Saint-Germain required a dramatic equaliser followed by a perfect penalty shootout to overcome their arch-rivals in Kuwait and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be sailing towards a straightforward win in the showdown between the Ligue 1 champions and the French Cup winners after Ousmane Dembele found the scoring in the opening stages.
However, the southern French side struck two times late to seize a surprise lead. Initially, the English forward converted from the spot-kick, before the defender inadvertently 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 seconds to send the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, saving crucial kicks from Matt O'Riley and Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored successfully for PSG to complete a 4-1 penalty victory.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now lifted this trophy for the 12th time in the past thirteen years.
