PSG has now won the season-opening cup on 14 different occasions.
The Parisian giants required a dramatic leveler followed by a perfect penalty shootout to get past their arch-rivals in Kuwait and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be sailing towards a straightforward triumph in the showdown between the Ligue 1 winners and the Coupe de France winners after the French winger found the scoring early on.
However, the southern French side fired twice in the closing moments to take a surprise lead. First, Mason Greenwood scored from the penalty spot, before the defender inadvertently turned the ball into his own net for an own-goal.
In a remarkable turn of events, Goncalo Ramos snatched a crucial leveler in the dying moments to send the contest into a penalty shootout. The Parisian shot-stopper Chevalier then emerged as the hero, stopping decisive attempts from Matt O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted successfully for Paris Saint-Germain to complete a convincing shootout win.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Olympique de Marseille after achieving a league and cup double, have now lifted this trophy for the 12th time in the past thirteen years.
