The Parisian club has now claimed the season-opening trophy on fourteen different occasions.
The Parisian giants required a dramatic leveler followed by a perfect spot-kick decider to get past their arch-rivals in the Gulf and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be sailing towards a straightforward triumph in the match between the French league champions and the Coupe de France winners after Ousmane Dembele found the scoring in the opening stages.
Yet, the southern French side fired twice in the closing moments to take a surprise advantage. First, Mason Greenwood scored from the penalty spot, before the defender unfortunately directed the ball into his own net for an own goal.
In a breathtaking turn of fortune, Goncalo Ramos snatched a crucial leveler in the final seconds to send the match into a penalty shootout. The Parisian shot-stopper Chevalier then stood as the key figure, saving decisive attempts from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and the young talent all scored with composure for PSG to complete a 4-1 penalty victory.
The record winners PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after achieving a domestic double, have now won this trophy for the twelfth time in the last 13 seasons.
