The Parisian club has now secured the prestigious cup on fourteen different times.
The Parisian giants required a dramatic equaliser followed by a perfect penalty shootout to overcome their arch-rivals in Kuwait and capture 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 Ligue 1 champions and the Coupe de France holders after the French winger opened the scoring early on.
However, Marseille fired two times in the closing moments to seize a shock lead. Initially, Mason Greenwood converted from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a remarkable turn of fortune, Goncalo Ramos snatched a vital equaliser in the final seconds to force the contest into a penalty shootout. The Parisian shot-stopper Chevalier then stood as the key figure, stopping crucial kicks from Matt O'Riley and Traore.
In the shootout, Ramos, the midfielder, the full-back, and the young talent all converted with composure for PSG to complete a convincing penalty win.
The record 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 twelfth time in the last thirteen years.
