The Parisian club has now claimed the prestigious trophy on fourteen separate times.
Paris Saint-Germain required a stoppage-time equaliser followed by a perfect penalty shootout to get past their arch-rivals in Kuwait and capture a record-extending fourth consecutive French Super Cup victory.
The Champions League holders appeared to be coasting towards a straightforward triumph in the match featuring the Ligue 1 champions and the French Cup holders after Ousmane Dembele found the scoring in the opening stages.
Yet, Marseille fired two times late to take a surprise advantage. Initially, Mason Greenwood scored from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own goal.
In a remarkable turn of fortune, Goncalo Ramos grabbed a vital leveler in the final moments to force the contest into a penalty shootout. PSG goalkeeper Chevalier then stood as the hero, saving decisive kicks from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and the young talent all scored successfully for PSG to complete a convincing shootout victory.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now lifted this competition for the 12th time in the past thirteen seasons.
