The Parisian club has now secured the prestigious cup on 14 separate occasions.
The Parisian giants required a dramatic leveler followed by a perfect penalty shootout to get past Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be coasting towards a comfortable win in the match featuring the French league winners and the French Cup holders after Ousmane Dembele found the net early on.
Yet, Marseille fired twice in the closing moments to take a surprise advantage. First, Mason Greenwood converted from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a breathtaking turn of events, the Portuguese striker grabbed a vital equaliser in the final moments to force the contest into a penalty shootout. The Parisian shot-stopper Chevalier then emerged as the hero, saving decisive attempts from Matt O'Riley and Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and the young talent all scored successfully for PSG to seal a 4-1 shootout victory.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now won this competition for the 12th time in the past 13 seasons.
