The Parisian club has now secured the season-opening cup on 14 separate times.
Paris Saint-Germain needed a stoppage-time leveler followed by a successful spot-kick decider to overcome Marseille in Kuwait and capture a fourth straight Trophee des Champions title.
The European champions seemed to be coasting towards a straightforward triumph in the match between the Ligue 1 champions and the Coupe de France winners after Ousmane Dembele found the net in the opening stages.
However, Marseille struck two times in the closing moments to take a surprise lead. First, the English forward scored from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a breathtaking turn of events, the Portuguese striker grabbed a vital leveler in the dying moments to send the contest into a deciding shootout. The Parisian shot-stopper Chevalier then emerged as the hero, saving decisive kicks from Matt O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all converted with composure for PSG to complete a convincing shootout win.
The record winners PSG, who met last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now won this trophy for the 12th time in the past 13 seasons.
