The Parisian club has now won the prestigious cup on 14 separate times.
The Parisian giants required a dramatic leveler followed by a successful spot-kick decider to overcome Marseille in Kuwait and capture a fourth straight French Super Cup title.
The Champions League holders seemed to be sailing towards a straightforward triumph in the showdown between the Ligue 1 champions and the Coupe de France winners after Ousmane Dembele opened the net in the opening stages.
However, the southern French side struck twice late to take a surprise advantage. Initially, the English forward scored from the spot-kick, before the defender inadvertently turned the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos snatched a crucial equaliser in the final seconds to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, stopping decisive attempts from O'Riley and Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and the young talent all converted successfully for PSG to seal a convincing penalty victory.
Now 14-time winners PSG, who faced last season's Ligue 1 runners-up Marseille after completing a domestic double, have now lifted this trophy for the 12th time in the last thirteen years.
