The Parisian club has now won the season-opening cup on 14 separate occasions.
The Parisian giants needed a stoppage-time equaliser followed by a perfect penalty shootout to get past their arch-rivals in Kuwait and capture a record-extending fourth consecutive French Super Cup victory.
The European champions seemed to be coasting towards a comfortable triumph in the match featuring the Ligue 1 winners and the Coupe de France holders after the French winger opened the scoring in the opening stages.
Yet, the southern French side fired twice late to seize a surprise lead. Initially, Mason Greenwood scored from the penalty spot, before the defender inadvertently 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 dying seconds to send the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, saving crucial attempts from Matt O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and the young talent all converted successfully for Paris Saint-Germain to seal a 4-1 shootout win.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now won this trophy for the 12th time in the last thirteen seasons.
