PSG has now secured the prestigious trophy on fourteen separate times.
Paris Saint-Germain required a stoppage-time leveler followed by a perfect penalty shootout to overcome their arch-rivals in Kuwait and capture a fourth straight Trophee des Champions victory.
The European champions seemed to be sailing towards a comfortable triumph in the showdown between the Ligue 1 champions and the Coupe de France holders after the French winger found the scoring early on.
Yet, the southern French side struck twice late to seize a shock advantage. Initially, Mason Greenwood scored from the spot-kick, before the defender inadvertently turned the ball into his own net for an own-goal.
In a breathtaking twist of events, Goncalo Ramos grabbed a crucial equaliser in the final moments to send the match into a deciding shootout. PSG goalkeeper Chevalier then stood as the key figure, saving crucial attempts from O'Riley and Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted successfully for Paris Saint-Germain to complete a 4-1 shootout win.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now lifted this trophy for the 12th time in the last thirteen seasons.
