PSG has now won the season-opening trophy on fourteen separate occasions.
Paris Saint-Germain required a dramatic leveler followed by a perfect penalty shootout to overcome their arch-rivals in Kuwait and capture a fourth straight French Super Cup title.
The European champions seemed to be sailing towards a comfortable triumph in the showdown featuring the French league champions and the Coupe de France holders after Ousmane Dembele found the scoring in the opening stages.
However, Marseille fired two times late to seize a surprise advantage. First, the English forward converted from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own goal.
In a breathtaking twist of events, Goncalo Ramos grabbed a vital equaliser in the final moments to send the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, stopping decisive attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all converted with composure for PSG to seal a 4-1 shootout win.
Now 14-time winners PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now lifted this trophy for the 12th time in the last 13 seasons.
