The Parisian club has now claimed the season-opening trophy on fourteen separate occasions.
Paris Saint-Germain needed a dramatic equaliser followed by a successful spot-kick decider to overcome their arch-rivals in Kuwait and capture a fourth straight French Super Cup victory.
The European champions seemed to be coasting towards a straightforward triumph in the showdown between the French league winners and the French Cup holders after the French winger found the scoring in the opening stages.
Yet, the southern French side struck two times in the closing moments to seize a shock lead. First, the English forward scored from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a breathtaking turn of fortune, the Portuguese striker snatched a vital equaliser in the dying moments to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping crucial kicks from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored with composure for Paris Saint-Germain to complete a convincing shootout victory.
The record winners PSG, who faced last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now won this competition for the 12th time in the last 13 seasons.
