PSG has now claimed the season-opening trophy on fourteen different occasions.
The Parisian giants required a dramatic leveler followed by a perfect spot-kick decider to get past Marseille in Kuwait and capture a fourth straight French Super Cup victory.
The Champions League holders seemed to be sailing towards a comfortable triumph in the showdown between the French league winners and the Coupe de France holders after Ousmane Dembele opened the scoring early on.
However, the southern French side struck twice late to seize a surprise lead. Initially, Mason Greenwood scored from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a remarkable twist of fortune, the Portuguese striker grabbed a vital equaliser in the dying moments to force the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, stopping crucial attempts from Matt O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and the young talent all converted with composure for Paris Saint-Germain to complete a convincing penalty victory.
The record winners PSG, who met last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now lifted this competition for the twelfth time in the past 13 seasons.
