PSG has now claimed the season-opening trophy on fourteen different times.
Paris Saint-Germain required a dramatic equaliser followed by a successful penalty shootout to overcome Marseille in Kuwait and capture a fourth straight French Super Cup victory.
The European champions appeared to be coasting towards a comfortable win in the showdown between the French league winners and the Coupe de France holders after Ousmane Dembele opened the scoring early on.
Yet, Marseille fired two times in the closing moments to take a surprise advantage. First, Mason Greenwood converted from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a remarkable turn of fortune, the Portuguese striker grabbed a crucial equaliser in the final moments to send the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, stopping crucial attempts from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and the young talent all scored with composure for Paris Saint-Germain to seal a 4-1 penalty victory.
The record champions PSG, who faced last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now won this competition for the twelfth time in the last 13 seasons.
