PSG has now secured the prestigious cup on fourteen different occasions.
The Parisian giants needed a dramatic equaliser followed by a perfect penalty shootout to get past their arch-rivals in Kuwait and secure a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders appeared to be sailing towards a straightforward triumph in the showdown featuring the Ligue 1 champions and the Coupe de France holders after Ousmane Dembele found the net early on.
Yet, the southern French side fired two times in the closing moments to take a surprise lead. Initially, the English forward scored from the penalty spot, before the defender inadvertently directed the ball into his own net for an own goal.
In a breathtaking turn of fortune, the Portuguese striker grabbed a vital leveler in the dying seconds to force the match into a deciding shootout. The Parisian shot-stopper Chevalier then emerged as the key figure, stopping decisive attempts from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all converted successfully for PSG to seal a convincing shootout win.
The record winners PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now lifted this competition for the twelfth time in the past thirteen seasons.
