The Parisian club has now claimed the season-opening cup on fourteen different times.
Paris Saint-Germain needed a dramatic equaliser followed by a perfect spot-kick decider to overcome their arch-rivals in Kuwait and capture a fourth straight French Super Cup victory.
The Champions League holders appeared to be coasting towards a comfortable triumph in the match between the French league winners and the French Cup winners after the French winger opened the scoring early on.
Yet, the southern French side struck two times in the closing moments to take a surprise lead. Initially, Mason Greenwood scored from the spot-kick, before the defender inadvertently directed the ball into his own net for an own-goal.
In a remarkable turn of events, the Portuguese striker grabbed a crucial equaliser in the dying seconds to force the match into a penalty shootout. PSG goalkeeper Chevalier then emerged as the key figure, saving crucial kicks from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and the young talent all scored successfully for PSG to seal a convincing shootout victory.
Now 14-time champions PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now won this trophy for the 12th time in the last 13 years.
