The Parisian club has now claimed the prestigious trophy on 14 different occasions.
The Parisian giants required a dramatic equaliser followed by a successful penalty shootout to get past their arch-rivals in Kuwait and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be sailing towards a comfortable triumph in the showdown between the French league champions and the French Cup holders after the French winger opened the scoring in the opening stages.
However, Marseille fired two times in the closing moments to take a shock advantage. Initially, Mason Greenwood scored from the spot-kick, before the defender inadvertently directed the ball into his own net for an own goal.
In a remarkable turn of fortune, Goncalo Ramos snatched a vital leveler in the dying seconds to send the match into a penalty shootout. PSG goalkeeper Chevalier then stood as the key figure, stopping decisive attempts from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and the young talent all converted with composure for Paris Saint-Germain to seal a 4-1 shootout victory.
Now 14-time champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now won this competition for the 12th time in the last 13 years.
