The Parisian club has now won the season-opening trophy on 14 different times.
The Parisian giants 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 victory.
The Champions League holders appeared to be sailing towards a comfortable triumph in the showdown between the Ligue 1 winners and the Coupe de France holders after Ousmane Dembele opened the scoring in the opening stages.
However, the southern French side fired two times in the closing moments to seize a shock advantage. First, Mason Greenwood converted from the penalty spot, before the defender inadvertently directed the ball into his own net for an own goal.
In a breathtaking turn of fortune, the Portuguese striker grabbed a crucial leveler in the dying seconds to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, saving decisive kicks from O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored successfully for Paris Saint-Germain to complete a 4-1 penalty victory.
Now 14-time winners 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 competition for the 12th time in the past 13 years.
