PSG has now won the season-opening trophy on 14 separate occasions.
The Parisian giants required a dramatic leveler followed by a successful penalty shootout to overcome Marseille in the Gulf and capture a fourth straight French Super Cup title.
The Champions League holders appeared to be coasting towards a comfortable win in the match between the French league champions and the Coupe de France winners after the French winger found the net early on.
Yet, the southern French side struck two times late to seize a surprise advantage. First, the English forward converted from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a remarkable turn of fortune, Goncalo Ramos snatched a vital equaliser in the dying moments to force the contest into a deciding shootout. PSG goalkeeper Chevalier then emerged as the key figure, stopping decisive attempts from O'Riley and Traore.
In the shootout, Ramos, the midfielder, the full-back, and the young talent all converted with composure for PSG to seal a 4-1 penalty win.
Now 14-time champions PSG, 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 thirteen seasons.
