The Parisian club has now won the season-opening trophy on 14 different times.
Paris Saint-Germain needed a dramatic leveler followed by a perfect spot-kick decider to get past their arch-rivals in Kuwait and secure a fourth straight French Super Cup victory.
The Champions League holders seemed to be coasting towards a straightforward win in the match between the French league champions and the Coupe de France winners after Ousmane Dembele opened the net in the opening stages.
However, the southern French side struck twice late to seize a shock advantage. First, Mason Greenwood converted from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos snatched a vital equaliser in the dying seconds to send the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, saving crucial attempts from O'Riley and Traore.
From the spot, Ramos, Vitinha, the full-back, and the young talent all converted successfully for PSG to complete a convincing penalty victory.
Now 14-time champions PSG, who faced last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now won this competition for the twelfth time in the past 13 seasons.
