PSG has now claimed the season-opening cup on 14 different times.
Paris Saint-Germain required a stoppage-time equaliser followed by a perfect penalty shootout to overcome Marseille in Kuwait and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be coasting towards a comfortable triumph in the match featuring the Ligue 1 champions and the French Cup winners after Ousmane Dembele opened the scoring in the opening stages.
However, the southern French side struck twice late to seize a surprise advantage. Initially, the English forward converted from the penalty spot, before the defender unfortunately turned the ball into his own net for an own-goal.
In a breathtaking twist of fortune, Goncalo Ramos grabbed a vital equaliser in the dying moments to force the match into a deciding shootout. The Parisian shot-stopper Chevalier then emerged as the hero, stopping decisive kicks from O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and Desire Doue all converted successfully for Paris Saint-Germain to complete a convincing penalty win.
Now 14-time champions PSG, who faced last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now lifted this competition for the twelfth time in the past 13 seasons.
