PSG has now won the prestigious cup on fourteen different times.
Paris Saint-Germain needed a dramatic leveler followed by a perfect penalty shootout to get past Marseille in Kuwait and capture a fourth straight French Super Cup title.
The European champions appeared to be coasting towards a straightforward win in the match featuring the Ligue 1 champions and the Coupe de France holders after the French winger found the net early on.
Yet, the southern French side struck two times late to seize a surprise lead. Initially, Mason Greenwood converted from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a remarkable turn of events, Goncalo Ramos grabbed a crucial leveler in the dying moments to force the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping crucial kicks from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and the young talent all scored with composure for Paris Saint-Germain to complete a 4-1 shootout victory.
Now 14-time winners PSG, who faced last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now lifted this competition for the 12th time in the past thirteen seasons.
