The Parisian club has now secured the season-opening trophy on 14 separate times.
Paris Saint-Germain needed a dramatic equaliser followed by a successful penalty shootout to overcome their arch-rivals in Kuwait and capture a fourth straight French Super Cup victory.
The Champions League holders seemed to be sailing towards a straightforward triumph in the match between the Ligue 1 winners and the French Cup holders after the French winger opened the scoring early on.
However, the southern French side struck two times in the closing moments to take a surprise lead. Initially, the English forward scored from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a remarkable turn of events, the Portuguese striker grabbed a vital equaliser in the final seconds to force the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, saving decisive attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored successfully for Paris Saint-Germain to complete a convincing penalty victory.
Now 14-time champions PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now lifted this trophy for the twelfth time in the last 13 seasons.
