PSG has now won the season-opening cup on fourteen different times.
Paris Saint-Germain needed a dramatic equaliser followed by a perfect penalty shootout to overcome Marseille in Kuwait and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be sailing towards a straightforward win in the match between the Ligue 1 champions and the French Cup holders after Ousmane Dembele found the net early on.
However, the southern French side struck two times late to seize a surprise lead. First, the English forward 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 events, Goncalo Ramos snatched a crucial equaliser in the dying moments to force the contest into a penalty shootout. PSG goalkeeper Chevalier then stood as the key figure, saving decisive kicks from Matt O'Riley and Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and the young talent all scored successfully for Paris Saint-Germain to seal a 4-1 penalty win.
Now 14-time champions Paris Saint-Germain, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now lifted this trophy for the 12th time in the past 13 years.
