The Parisian club has now secured the prestigious cup on fourteen different occasions.
The Parisian giants required a dramatic leveler followed by a successful penalty shootout to get past their arch-rivals in Kuwait and capture a fourth straight Trophee des Champions victory.
The European champions seemed to be coasting towards a straightforward win in the match featuring the Ligue 1 champions and the Coupe de France winners after Ousmane Dembele opened the scoring early on.
Yet, Marseille struck twice in the closing moments to take a surprise advantage. First, Mason Greenwood converted from the spot-kick, before the defender unfortunately turned 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 send the match into a penalty shootout. The Parisian shot-stopper Chevalier then emerged as the key figure, stopping crucial attempts from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and the young talent all scored successfully for PSG to seal a 4-1 shootout win.
The record winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now lifted this competition for the twelfth time in the past thirteen seasons.
