The Parisian club has now secured the prestigious cup on fourteen different occasions.
Paris Saint-Germain needed a stoppage-time equaliser followed by a successful penalty shootout to overcome Marseille in the Gulf and secure a fourth straight French Super Cup title.
The European champions appeared to be coasting towards a straightforward win in the showdown featuring the French league winners and the French Cup holders after Ousmane Dembele opened the net early on.
However, the southern French side fired two times in the closing moments to seize a shock lead. First, Mason Greenwood converted from the penalty spot, before the defender unfortunately turned the ball into his own net for an own goal.
In a remarkable twist of fortune, Goncalo Ramos snatched a crucial equaliser in the dying seconds to send the contest into a deciding shootout. PSG goalkeeper Chevalier then stood as the hero, saving decisive attempts from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted with composure for Paris Saint-Germain to seal a 4-1 penalty victory.
The record champions PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now won this competition for the 12th time in the past thirteen years.
