PSG has now secured the season-opening cup on fourteen different times.
The Parisian giants required a dramatic leveler followed by a successful penalty shootout to overcome Marseille in Kuwait and secure a fourth straight Trophee des Champions title.
The European champions appeared to be sailing towards a comfortable triumph in the match featuring the French league champions and the French Cup winners after Ousmane Dembele found the net in the opening stages.
However, the southern French side fired twice in the closing moments to take a surprise lead. Initially, the English forward scored from the penalty spot, before the defender unfortunately directed the ball into his own net for an own-goal.
In a remarkable twist of fortune, Goncalo Ramos snatched a vital leveler in the dying moments to force the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, stopping decisive kicks from O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored successfully for Paris Saint-Germain to complete a 4-1 penalty victory.
The record champions PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now lifted this trophy for the twelfth time in the past 13 seasons.
