The Parisian club has now won the prestigious trophy on fourteen separate times.
Paris Saint-Germain required a stoppage-time equaliser followed by a perfect spot-kick decider to overcome their arch-rivals in Kuwait and capture a record-extending fourth consecutive French Super Cup victory.
The Champions League holders appeared to be sailing towards a straightforward win in the showdown featuring the French league champions and the Coupe de France winners after Ousmane Dembele found the net in the opening stages.
Yet, the southern French side fired two times in the closing moments to seize a shock advantage. First, the English forward scored from the spot-kick, before the defender inadvertently turned the ball into his own net for an own-goal.
In a breathtaking turn of events, Goncalo Ramos snatched a vital equaliser in the final seconds to force the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, stopping crucial kicks 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 4-1 penalty win.
The record winners PSG, who faced last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now won this trophy for the twelfth time in the last 13 seasons.
