PSG has now claimed the prestigious trophy on 14 separate occasions.
Paris Saint-Germain required a dramatic leveler followed by a perfect penalty shootout to overcome their arch-rivals in Kuwait and secure a fourth straight 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 winners after Ousmane Dembele found the net early on.
However, the southern French side fired two times in the closing moments to seize a shock lead. First, Mason Greenwood scored from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a breathtaking turn of fortune, Goncalo Ramos snatched a crucial equaliser in the dying seconds to send the contest into a penalty shootout. The Parisian shot-stopper Chevalier then emerged as the key figure, stopping decisive kicks from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all scored successfully for Paris Saint-Germain to seal a convincing penalty win.
The record winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now won this competition for the 12th time in the past 13 years.
