PSG has now won the prestigious trophy on 14 separate times.
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 French Super Cup title.
The Champions League holders appeared to be sailing towards a straightforward triumph in the showdown between the Ligue 1 winners and the Coupe de France winners after the French winger opened the net early on.
Yet, the southern French side struck twice late to take a shock lead. First, the English forward converted from the spot-kick, before the defender inadvertently turned the ball into his own net for an own-goal.
In a remarkable turn of fortune, Goncalo Ramos snatched a crucial equaliser in the dying moments to force the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, stopping crucial attempts from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and the young talent all scored successfully for PSG to seal a convincing penalty victory.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now lifted this competition for the 12th time in the past thirteen seasons.
