The Parisian club has now claimed the prestigious cup on 14 different occasions.
The Parisian giants needed a dramatic leveler followed by a perfect penalty shootout to get past their arch-rivals in Kuwait and secure a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders appeared to be sailing towards a comfortable win in the showdown featuring the Ligue 1 champions and the French Cup holders after the French winger opened the scoring in the opening stages.
However, Marseille struck twice late to seize a surprise lead. First, Mason Greenwood scored from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a remarkable turn of events, Goncalo Ramos snatched a crucial leveler in the dying moments to send the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, stopping crucial attempts from O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and the young talent all scored successfully for Paris Saint-Germain to complete a convincing penalty victory.
The record winners PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now lifted this trophy for the twelfth time in the past thirteen seasons.
