PSG has now secured the prestigious trophy on fourteen different times.
Paris Saint-Germain required a dramatic leveler followed by a successful penalty shootout to get past their arch-rivals in Kuwait and capture a fourth straight Trophee des Champions victory.
The European champions appeared to be sailing towards a comfortable triumph in the match featuring the Ligue 1 winners and the French Cup winners after Ousmane Dembele found the net in the opening stages.
However, Marseille struck two times in the closing moments to seize a shock advantage. Initially, Mason Greenwood scored from the penalty spot, before the defender unfortunately turned the ball into his own net for an own goal.
In a remarkable turn of events, Goncalo Ramos grabbed a vital leveler in the dying seconds to send the contest into a deciding shootout. PSG goalkeeper Chevalier then emerged as the hero, stopping crucial attempts from O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to complete a 4-1 shootout victory.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now lifted this trophy for the twelfth time in the last thirteen years.
