The Parisian club has now secured the season-opening trophy on fourteen separate times.
The Parisian giants required a stoppage-time equaliser followed by a successful spot-kick decider to get past their arch-rivals in Kuwait and secure a fourth straight French Super Cup victory.
The Champions League holders appeared to be sailing towards a straightforward win in the showdown featuring the Ligue 1 champions and the French Cup holders after Ousmane Dembele found the scoring early on.
However, the southern French side struck twice in the closing moments to take a shock lead. First, Mason Greenwood converted from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own goal.
In a remarkable turn of fortune, the Portuguese striker grabbed a vital equaliser in the dying moments to force the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, saving decisive kicks from O'Riley and Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored successfully for PSG to complete a 4-1 shootout victory.
Now 14-time winners PSG, who met last season's Ligue 1 runners-up Marseille after completing a domestic double, have now won this trophy for the 12th time in the last 13 years.
