The Parisian club has now secured the season-opening cup on 14 separate times.
The Parisian giants needed a stoppage-time leveler followed by a perfect spot-kick decider to overcome Marseille in the Gulf and secure a fourth straight Trophee des Champions title.
The European champions appeared to be sailing towards a straightforward win in the match featuring the French league winners and the Coupe de France holders after Ousmane Dembele opened the net in the opening stages.
Yet, the southern French side struck two times in the closing moments to take a shock advantage. First, the English forward converted from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a remarkable twist of events, the Portuguese striker grabbed a vital equaliser in the dying seconds to force the match into a penalty shootout. The Parisian shot-stopper Chevalier then emerged as the key figure, stopping decisive attempts from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all converted successfully for PSG to seal 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 domestic double, have now won this trophy for the twelfth time in the past 13 seasons.
