PSG has now won the season-opening cup on fourteen different times.
The Parisian giants required a dramatic leveler followed by a perfect penalty shootout to overcome their arch-rivals in Kuwait and secure a fourth straight French Super Cup title.
The Champions League holders appeared to be coasting towards a comfortable triumph in the match featuring the French league winners and the French Cup holders after Ousmane Dembele found the scoring early on.
However, the southern French side fired twice late to seize a surprise lead. Initially, the English forward converted from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a remarkable turn of events, Goncalo Ramos grabbed a crucial equaliser in the final moments to send the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, saving crucial attempts from O'Riley and Traore.
From the spot, Ramos, Vitinha, the full-back, and the young talent all converted with composure for PSG to complete a 4-1 penalty victory.
Now 14-time champions PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now lifted this competition for the 12th time in the past thirteen years.
