PSG has now secured the season-opening cup on fourteen separate occasions.
The Parisian giants needed a dramatic leveler followed by a perfect penalty shootout to get past Marseille in the Gulf and secure a fourth straight Trophee des Champions victory.
The European champions appeared to be sailing towards a comfortable win in the showdown between the French league winners and the French Cup winners after the French winger found the net in the opening stages.
However, the southern French side fired two times late to seize a surprise lead. First, the English forward converted from the penalty spot, before the defender inadvertently turned the ball into his own net for an own goal.
In a remarkable turn of events, Goncalo Ramos grabbed a vital equaliser in the final moments to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving decisive kicks from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, the full-back, and Desire Doue all scored with composure for PSG to seal a 4-1 shootout win.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after completing a domestic double, have now won this competition for the twelfth time in the past 13 seasons.
