The Parisian club has now won the season-opening cup on fourteen different occasions.
Paris Saint-Germain needed a stoppage-time equaliser followed by a perfect penalty shootout to get past their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions title.
The European champions seemed 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.
However, Marseille fired twice late to take a surprise advantage. First, 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 turn of events, the Portuguese striker grabbed a crucial equaliser in the final seconds to force the contest into a penalty shootout. The Parisian shot-stopper Chevalier then stood as the hero, saving crucial attempts from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, the full-back, and Desire Doue all converted with composure for Paris Saint-Germain to seal a convincing shootout victory.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now won this competition for the twelfth time in the past 13 years.
