PSG has now secured the prestigious trophy on 14 separate times.
The Parisian giants needed a dramatic leveler followed by a successful spot-kick decider to get past Marseille in the Gulf and capture a record-extending fourth consecutive French Super Cup victory.
The European champions seemed to be coasting towards a straightforward triumph in the showdown featuring the Ligue 1 winners and the Coupe de France winners after Ousmane Dembele found the net early on.
Yet, the southern French side fired two times late to take a shock lead. First, the English forward scored from the penalty spot, before the defender inadvertently directed the ball into his own net for an own goal.
In a remarkable turn of fortune, Goncalo Ramos snatched a vital leveler in the dying moments to force the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, saving crucial attempts from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all converted successfully for Paris Saint-Germain to seal a convincing penalty win.
The record champions PSG, who faced last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now won this competition for the 12th time in the last 13 seasons.
