The Parisian club has now claimed the prestigious cup on 14 different times.
The Parisian giants needed a dramatic equaliser followed by a perfect penalty shootout to get past Marseille in the Gulf and secure a record-extending fourth consecutive French Super Cup victory.
The Champions League holders appeared to be coasting towards a comfortable win in the match featuring the Ligue 1 winners and the Coupe de France holders after the French winger found the net early on.
Yet, Marseille fired twice in the closing moments to seize a surprise advantage. Initially, 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 fortune, Goncalo Ramos snatched a vital leveler in the dying seconds to force the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, saving crucial attempts from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all converted with composure for Paris Saint-Germain to seal a 4-1 shootout win.
Now 14-time champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a domestic double, have now lifted this trophy for the 12th time in the last 13 seasons.
