PSG has now won the season-opening cup on fourteen separate times.
Paris Saint-Germain needed a stoppage-time equaliser followed by a perfect spot-kick decider to get past Marseille in the Gulf and capture a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders seemed to be sailing towards a comfortable triumph in the match between the Ligue 1 winners and the French Cup winners after Ousmane Dembele opened the scoring in the opening stages.
Yet, the southern French side struck two times in the closing moments to seize a surprise lead. Initially, the English forward converted from the penalty spot, before the defender unfortunately directed the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos snatched a vital equaliser in the final moments to force the contest into a deciding shootout. The Parisian shot-stopper Chevalier then emerged as the hero, stopping decisive attempts from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and the young talent all converted successfully for PSG to complete a convincing penalty victory.
Now 14-time champions PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now lifted this trophy for the twelfth time in the last 13 seasons.
