PSG has now won the prestigious trophy on fourteen separate times.
The Parisian giants required a stoppage-time equaliser followed by a successful penalty shootout to get past Marseille in the Gulf and secure a fourth straight French Super Cup title.
The European champions appeared to be coasting towards a comfortable triumph in the showdown featuring the Ligue 1 champions and the Coupe de France holders after Ousmane Dembele opened the net in the opening stages.
Yet, the southern French side struck two times late to take a surprise 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 twist of events, the Portuguese striker snatched a vital leveler in the dying seconds to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping decisive kicks from O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all scored successfully for PSG to complete a 4-1 penalty win.
The record winners PSG, who faced 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 past 13 years.
