The Parisian club has now won the season-opening cup on fourteen separate occasions.
Paris Saint-Germain required a stoppage-time leveler followed by a successful penalty shootout to get past their arch-rivals in Kuwait and secure a record-extending fourth consecutive Trophee des Champions victory.
The European champions appeared to be sailing towards a comfortable triumph in the showdown featuring the Ligue 1 champions and the Coupe de France winners after the French winger found the net early on.
Yet, the southern French side fired twice late to take a shock advantage. 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 remarkable twist of fortune, Goncalo Ramos snatched a vital leveler in the final moments to send the contest into a penalty shootout. The Parisian shot-stopper Chevalier then emerged as the hero, saving crucial attempts from O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to complete a 4-1 penalty win.
Now 14-time champions PSG, who faced last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now lifted this trophy for the twelfth time in the past thirteen seasons.
