PSG has now secured the prestigious cup on 14 separate occasions.
The Parisian giants required a dramatic equaliser followed by a successful spot-kick decider to get past Marseille in Kuwait and secure a record-extending fourth consecutive French Super Cup victory.
The Champions League holders appeared to be coasting towards a comfortable triumph in the match featuring the Ligue 1 winners and the Coupe de France holders after Ousmane Dembele opened the net in the opening stages.
Yet, the southern French side fired two times in the closing moments to seize a shock advantage. First, Mason Greenwood converted from the penalty spot, before the defender unfortunately directed the ball into his own net for an own-goal.
In a remarkable twist of events, Goncalo Ramos grabbed a vital equaliser in the final moments to send the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, saving crucial kicks from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to complete a convincing penalty win.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now lifted this trophy for the 12th time in the past thirteen seasons.
