PSG has now won the season-opening cup on 14 different occasions.
Paris Saint-Germain needed a dramatic leveler followed by a successful penalty shootout to get past their arch-rivals in Kuwait and capture a fourth straight Trophee des Champions victory.
The European champions seemed to be sailing towards a comfortable win in the match between the French league champions and the French Cup holders after the French winger opened the scoring in the opening stages.
However, the southern French side fired two times in the closing moments to take a surprise advantage. First, Mason Greenwood scored from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a remarkable turn of fortune, the Portuguese striker 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 hero, stopping crucial kicks from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and the young talent all converted with composure for Paris Saint-Germain to seal a convincing shootout win.
Now 14-time winners PSG, who met last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now won this trophy for the twelfth time in the last 13 years.
