The Parisian club has now won the prestigious cup on fourteen separate occasions.
The Parisian giants required a stoppage-time leveler followed by a successful penalty shootout to overcome their arch-rivals in Kuwait and capture a fourth straight French Super Cup title.
The European champions seemed to be coasting towards a comfortable triumph in the showdown featuring the Ligue 1 winners and the French Cup winners after the French winger opened the net early on.
Yet, the southern French side fired two times in the closing moments to seize a shock lead. First, Mason Greenwood scored from the spot-kick, before the defender unfortunately directed the ball into his own net for an own goal.
In a remarkable twist of events, the Portuguese striker grabbed a vital equaliser in the final seconds to force the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, saving decisive kicks from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and the young talent all scored with composure for PSG to seal a 4-1 shootout win.
The record champions PSG, who met last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now lifted this trophy for the twelfth time in the past thirteen seasons.
