The Parisian club has now won the season-opening cup on 14 separate times.
The Parisian giants required a stoppage-time equaliser followed by a successful penalty shootout to get past their arch-rivals in Kuwait and capture a record-extending fourth consecutive French Super Cup title.
The Champions League holders appeared to be coasting towards a straightforward triumph in the showdown featuring the Ligue 1 champions and the French Cup winners after the French winger found the net in the opening stages.
Yet, the southern French side struck two times in the closing moments to take a surprise advantage. First, Mason Greenwood scored from the penalty spot, before the defender inadvertently directed the ball into his own net for an own goal.
In a remarkable twist of fortune, the Portuguese striker grabbed a vital equaliser in the final moments to force the match into a deciding shootout. The Parisian shot-stopper Chevalier then emerged as the key figure, saving crucial attempts from Matt O'Riley and Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted with composure for Paris Saint-Germain to complete a 4-1 shootout victory.
Now 14-time winners PSG, who faced last season's Ligue 1 runners-up Marseille after completing a domestic double, have now lifted this competition for the twelfth time in the last thirteen seasons.
