PSG has now claimed the season-opening cup on 14 different times.
The Parisian giants required a stoppage-time equaliser followed by a successful penalty shootout to overcome Marseille in the Gulf and capture a fourth straight French Super Cup title.
The European champions appeared to be sailing towards a comfortable win in the showdown between the French league champions and the French Cup winners after Ousmane Dembele opened the net in the opening stages.
However, the southern French side struck two times late to seize a shock advantage. Initially, 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, the Portuguese striker snatched a crucial equaliser in the dying seconds to send the match into a deciding shootout. PSG goalkeeper Chevalier then emerged as the hero, stopping decisive attempts from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all scored successfully for PSG to seal a convincing shootout victory.
Now 14-time champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now lifted this trophy for the 12th time in the past 13 years.
