PSG has now secured the season-opening cup on fourteen separate occasions.
Paris Saint-Germain 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 victory.
The European champions appeared to be sailing towards a comfortable win in the showdown between the Ligue 1 winners and the Coupe de France winners after the French winger opened the scoring early on.
However, Marseille fired two times in the closing moments to seize a shock lead. First, the English forward scored from the spot-kick, before the defender unfortunately turned the ball into his own net for an own-goal.
In a breathtaking turn of events, Goncalo Ramos grabbed a vital equaliser in the final moments to send the match into a deciding shootout. PSG goalkeeper Chevalier then emerged as the hero, saving decisive kicks from O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and the young talent all converted with composure for Paris Saint-Germain to seal a 4-1 penalty victory.
The record winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now won this competition for the 12th time in the last 13 years.
