PSG has now secured the season-opening cup on fourteen separate occasions.
The Parisian giants required a stoppage-time leveler followed by a successful spot-kick decider to get past Marseille in the Gulf and secure a fourth straight French Super Cup title.
The European champions seemed to be coasting towards a straightforward win in the showdown between the Ligue 1 winners and the French Cup holders after the French winger opened the net in the opening stages.
However, the southern French side struck two times late to take a surprise lead. First, Mason Greenwood scored from the penalty spot, before the defender unfortunately directed the ball into his own net for an own goal.
In a breathtaking turn of events, the Portuguese striker grabbed a vital equaliser in the dying moments to force the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, saving crucial kicks from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and the young talent all converted successfully for PSG to complete a 4-1 shootout win.
Now 14-time winners PSG, who met last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now won this trophy for the twelfth time in the past 13 years.
