The Parisian club has now claimed the season-opening cup on fourteen different occasions.
Paris Saint-Germain required a stoppage-time equaliser followed by a successful penalty shootout to get past Marseille in Kuwait and secure a fourth straight Trophee des Champions victory.
The European champions seemed to be sailing towards a straightforward win in the showdown between the French league champions and the Coupe de France winners after Ousmane Dembele found the net early on.
However, the southern French side fired two times late to take a shock advantage. Initially, the English forward scored from the spot-kick, before the defender unfortunately directed the ball into his own net for an own goal.
In a remarkable twist of fortune, the Portuguese striker grabbed a crucial equaliser in the final seconds to send the contest into a penalty shootout. The Parisian shot-stopper Chevalier then stood as the key figure, saving crucial kicks from O'Riley and Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored successfully for PSG to seal a convincing shootout victory.
Now 14-time champions PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now won this competition for the 12th time in the past thirteen seasons.
