PSG has now secured the season-opening cup on 14 different occasions.
The Parisian giants needed a dramatic equaliser followed by a successful penalty shootout to get past Marseille in Kuwait and capture a fourth straight French Super Cup title.
The Champions League holders seemed to be coasting towards a straightforward triumph in the match between the French league winners and the Coupe de France winners after the French winger found the scoring early on.
Yet, Marseille fired twice late to seize a shock advantage. Initially, Mason Greenwood converted from the spot-kick, before the defender unfortunately directed the ball into his own net for an own goal.
In a remarkable turn of fortune, the Portuguese striker snatched a vital equaliser in the final moments to send the contest into a penalty shootout. PSG goalkeeper Chevalier then emerged as the hero, saving crucial kicks from O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all scored with composure for PSG to complete a 4-1 shootout victory.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now won this trophy for the 12th time in the past thirteen seasons.
