The Parisian club has now claimed the prestigious trophy on fourteen separate occasions.
The Parisian giants needed a dramatic equaliser followed by a successful spot-kick decider to get past Marseille in Kuwait and secure a fourth straight Trophee des Champions title.
The European champions seemed to be sailing towards a straightforward triumph in the showdown between the Ligue 1 winners and the Coupe de France holders after the French winger opened the net early on.
Yet, Marseille fired twice late to take a surprise advantage. Initially, 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 twist of fortune, Goncalo Ramos snatched a vital leveler in the dying moments to force the contest into a penalty shootout. PSG goalkeeper Chevalier then emerged as the key figure, saving crucial kicks from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and the young talent all converted successfully for Paris Saint-Germain to complete a 4-1 shootout victory.
Now 14-time champions PSG, who faced last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now lifted this trophy for the 12th time in the last thirteen years.
