PSG has now claimed the season-opening cup on fourteen different occasions.
The Parisian giants required a dramatic leveler followed by a perfect spot-kick decider to get past Marseille in Kuwait and secure a fourth straight French Super Cup title.
The Champions League holders seemed to be coasting towards a comfortable triumph in the showdown between the Ligue 1 champions and the French Cup holders after Ousmane Dembele found the scoring early on.
However, Marseille struck twice in the closing moments to take a shock lead. First, the English forward scored from the penalty spot, before the defender unfortunately directed the ball into his own net for an own goal.
In a remarkable turn of fortune, the Portuguese striker grabbed a crucial equaliser in the final seconds to force the contest into a deciding shootout. PSG goalkeeper Chevalier then emerged as the hero, saving decisive attempts from O'Riley and Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to seal a 4-1 penalty victory.
The record champions PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now lifted this trophy for the 12th time in the past thirteen years.
