The Parisian club has now secured the season-opening cup on 14 different occasions.
The Parisian giants needed a stoppage-time leveler followed by a successful penalty shootout to overcome Marseille in the Gulf and capture a fourth straight French Super Cup victory.
The European champions seemed to be coasting towards a straightforward triumph in the match between the French league champions and the Coupe de France holders after the French winger opened the net early on.
Yet, the southern French side struck twice in the closing moments to seize a surprise lead. Initially, the English forward converted from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own goal.
In a remarkable twist of fortune, the Portuguese striker grabbed a crucial equaliser in the final seconds to send the contest into a penalty shootout. PSG goalkeeper Chevalier then emerged as the key figure, stopping decisive kicks from O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and Desire Doue all scored successfully for PSG to complete a 4-1 shootout win.
The record champions PSG, who met last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now won this competition for the twelfth time in the past thirteen seasons.
