PSG has now secured the season-opening cup on fourteen different occasions.
Paris Saint-Germain needed a dramatic leveler followed by a successful penalty shootout to overcome their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions victory.
The European champions seemed to be coasting towards a straightforward win in the showdown featuring the Ligue 1 winners and the Coupe de France holders after Ousmane Dembele opened the scoring early on.
However, the southern French side fired twice late to seize a shock lead. Initially, the English forward converted from the penalty spot, before the defender unfortunately directed the ball into his own net for an own-goal.
In a breathtaking twist of events, the Portuguese striker snatched a crucial equaliser in the final moments to force the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, saving decisive kicks from Matt O'Riley and Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted with composure for Paris Saint-Germain to seal a 4-1 shootout win.
Now 14-time 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 twelfth time in the past 13 seasons.
