The Parisian club has now secured the prestigious cup on fourteen different occasions.
Paris Saint-Germain needed a stoppage-time leveler followed by a successful penalty shootout to overcome Marseille 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 showdown between the French league winners and the French Cup holders after Ousmane Dembele opened the scoring in the opening stages.
However, the southern French side fired twice late to seize a surprise advantage. First, the English forward converted from the spot-kick, before the defender unfortunately turned the ball into his own net for an own-goal.
In a remarkable turn of events, the Portuguese striker grabbed a crucial equaliser in the dying moments to send the contest into a deciding shootout. The Parisian shot-stopper Chevalier then emerged as the key figure, stopping crucial kicks from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all converted successfully for PSG to seal a 4-1 shootout win.
The record champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now lifted this competition for the 12th time in the past 13 seasons.
