The Parisian club has now claimed the prestigious cup on 14 different times.
The Parisian giants needed a dramatic equaliser followed by a successful penalty shootout to overcome Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions victory.
The European champions appeared to be sailing towards a straightforward triumph in the match featuring the French league winners and the Coupe de France holders after Ousmane Dembele found the scoring early on.
However, Marseille fired twice in the closing moments to take a shock lead. First, Mason Greenwood converted from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a breathtaking twist of events, the Portuguese striker snatched a vital leveler in the final moments to force the match into a deciding shootout. PSG goalkeeper Chevalier then emerged as the key figure, stopping crucial kicks from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored with composure for PSG to complete a convincing penalty win.
Now 14-time champions PSG, who faced last season's Ligue 1 runners-up Marseille after completing a domestic double, have now won this trophy for the 12th time in the last 13 years.
