The Parisian club has now claimed the prestigious trophy on 14 different occasions.
The Parisian giants required a dramatic leveler followed by a successful penalty shootout to get past their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions title.
The Champions League holders seemed to be coasting towards a straightforward triumph in the match featuring the French league winners and the Coupe de France winners after Ousmane Dembele opened the net early on.
Yet, Marseille fired two times in the closing moments to take a surprise lead. First, the English forward converted from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a breathtaking turn of events, Goncalo Ramos grabbed a crucial leveler in the dying seconds to send the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, saving decisive attempts from Matt O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, the full-back, and the young talent all converted successfully for PSG to complete a 4-1 shootout win.
Now 14-time winners PSG, who met last season's Ligue 1 runners-up Marseille after completing a domestic double, have now lifted this trophy for the 12th time in the last 13 seasons.
