PSG has now claimed the season-opening trophy on 14 separate times.
Paris Saint-Germain needed a dramatic equaliser followed by a perfect penalty shootout to get past their arch-rivals in Kuwait and secure a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders seemed to be coasting towards a comfortable triumph in the match between the Ligue 1 champions and the Coupe de France holders after Ousmane Dembele found the scoring in the opening stages.
Yet, the southern French side fired two times in the closing moments to seize a surprise lead. Initially, the English forward scored from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a remarkable twist of fortune, Goncalo Ramos snatched a vital equaliser in the final moments to force the contest into a deciding shootout. The Parisian shot-stopper Chevalier then emerged as the hero, stopping decisive kicks from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all scored successfully for PSG to complete a 4-1 penalty win.
The record champions PSG, who met last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now won this trophy for the twelfth time in the past thirteen seasons.
