The Parisian club has now secured the prestigious cup on fourteen separate occasions.
The Parisian giants required a stoppage-time equaliser followed by a successful spot-kick decider to overcome Marseille in Kuwait and secure a fourth straight French Super Cup title.
The Champions League holders appeared to be sailing towards a comfortable triumph in the showdown between the French league winners and the French Cup holders after Ousmane Dembele found the scoring early on.
Yet, the southern French side fired two times late to take a surprise advantage. First, Mason Greenwood scored from the spot-kick, before the defender inadvertently turned the ball into his own net for an own goal.
In a remarkable turn of events, Goncalo Ramos grabbed a crucial equaliser in the dying seconds to force the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, stopping decisive kicks from Matt O'Riley and Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted with composure for PSG to complete a 4-1 penalty victory.
The record winners PSG, who faced last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now lifted this trophy for the 12th time in the past thirteen years.
