PSG has now secured the season-opening cup on 14 separate times.
Paris Saint-Germain required a stoppage-time leveler followed by a successful penalty shootout to get past Marseille in the Gulf and secure a fourth straight Trophee des Champions victory.
The Champions League holders seemed to be coasting towards a straightforward triumph in the match featuring the French league champions and the French Cup winners after the French winger opened the scoring early on.
Yet, the southern French side fired two times late to seize a shock lead. Initially, Mason Greenwood converted from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a breathtaking turn of fortune, Goncalo Ramos snatched a crucial equaliser in the final moments to force the match into a penalty shootout. The Parisian shot-stopper Chevalier then stood as the hero, saving decisive kicks from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and Desire Doue all converted successfully for Paris Saint-Germain to complete a 4-1 penalty win.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now won this competition for the 12th time in the last thirteen years.
