The Parisian club has now won the season-opening trophy on 14 separate times.
Paris Saint-Germain needed a stoppage-time equaliser followed by a perfect penalty shootout to overcome Marseille in the Gulf and capture a fourth straight French Super Cup title.
The Champions League holders seemed to be coasting towards a straightforward win in the showdown featuring the French league winners and the French Cup winners after the French winger found the net early on.
Yet, the southern French side struck twice late to take a shock advantage. First, Mason Greenwood 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, the Portuguese striker snatched a crucial equaliser in the dying moments to force the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving crucial kicks from Matt O'Riley and Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted successfully for PSG to seal a 4-1 penalty win.
The record winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now lifted this trophy for the 12th time in the last 13 seasons.
