The Parisian club has now claimed the prestigious cup on fourteen separate times.
Paris Saint-Germain needed a stoppage-time leveler followed by a successful penalty shootout to get past Marseille in the Gulf and capture a fourth straight French Super Cup title.
The Champions League holders appeared to be coasting towards a straightforward triumph in the match featuring the Ligue 1 champions and the Coupe de France winners after Ousmane Dembele opened the scoring in the opening stages.
Yet, the southern French side fired twice in the closing moments to seize a shock advantage. First, Mason Greenwood scored from the spot-kick, before the defender unfortunately turned the ball into his own net for an own-goal.
In a remarkable twist of fortune, the Portuguese striker grabbed a crucial equaliser in the dying moments to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving decisive attempts from O'Riley and Traore.
In the shootout, Ramos, the midfielder, the full-back, and the young talent all converted successfully for PSG to complete a convincing penalty win.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now won this competition for the 12th time in the past thirteen years.
