PSG has now claimed the prestigious trophy on fourteen separate times.
The Parisian giants needed a stoppage-time leveler followed by a successful penalty shootout to get past their arch-rivals in Kuwait and secure a record-extending fourth consecutive Trophee des Champions victory.
The European champions seemed to be sailing towards a straightforward triumph in the match between the Ligue 1 winners and the French Cup holders after the French winger opened the scoring early on.
Yet, Marseille fired two times in the closing moments to take a surprise lead. Initially, Mason Greenwood converted from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own goal.
In a breathtaking twist of events, Goncalo Ramos grabbed a vital leveler in the final seconds to force the contest into a deciding shootout. The Parisian shot-stopper Chevalier then stood as the key figure, stopping decisive attempts from O'Riley and Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and the young talent all scored successfully for Paris Saint-Germain to seal a 4-1 shootout win.
Now 14-time winners PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now lifted this competition for the 12th time in the last 13 years.
