The Parisian club has now claimed the season-opening cup on 14 different occasions.
The Parisian giants required a stoppage-time leveler followed by a perfect penalty shootout to overcome Marseille in Kuwait and secure a fourth straight French Super Cup victory.
The European champions seemed to be sailing towards a straightforward win in the showdown featuring the French league winners and the Coupe de France holders after Ousmane Dembele found the net in the opening stages.
Yet, the southern French side fired twice in the closing moments to seize a shock advantage. Initially, the English forward 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, the Portuguese striker grabbed a crucial equaliser in the final seconds to force the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving crucial kicks from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and the young talent all converted successfully for PSG to complete a 4-1 penalty win.
The record champions PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now lifted this competition for the 12th time in the past thirteen seasons.
