The Parisian club has now secured the prestigious cup on fourteen separate times.
The Parisian giants required a stoppage-time equaliser followed by a successful penalty shootout to overcome their arch-rivals in Kuwait and capture a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders seemed to be sailing towards a comfortable triumph in the showdown featuring the French league winners and the French Cup holders after the French winger opened the scoring early on.
Yet, the southern French side fired twice late to seize a surprise lead. First, the English forward scored from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a remarkable turn of events, Goncalo Ramos grabbed a vital equaliser in the dying moments to send the contest into a penalty shootout. The Parisian shot-stopper Chevalier then stood as the hero, saving crucial attempts from Matt O'Riley and Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to complete a 4-1 shootout win.
Now 14-time champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now won this competition for the 12th time in the last thirteen seasons.
