PSG has now won the prestigious cup on fourteen different times.
The Parisian giants required a dramatic leveler followed by a successful spot-kick decider to get past Marseille in Kuwait and capture a fourth straight French Super Cup victory.
The Champions League holders seemed to be sailing towards a straightforward win in the match featuring the Ligue 1 winners and the Coupe de France winners after Ousmane Dembele opened the scoring early on.
Yet, the southern French side struck two times in the closing moments to seize a shock lead. Initially, the English forward converted from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a breathtaking turn of fortune, Goncalo Ramos grabbed a vital equaliser in the final moments to force the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, saving decisive attempts from O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, the full-back, and the young talent all converted with composure for Paris Saint-Germain to complete a 4-1 shootout victory.
The record champions PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now won this trophy for the 12th time in the last thirteen years.
