PSG has now won the season-opening cup on fourteen separate occasions.
Paris Saint-Germain needed a dramatic equaliser followed by a perfect spot-kick decider to overcome Marseille in Kuwait and capture a record-extending fourth consecutive French Super Cup victory.
The European champions appeared to be coasting towards a comfortable win in the showdown featuring the French league champions and the French Cup holders after Ousmane Dembele opened the scoring early on.
Yet, Marseille struck twice late to seize a surprise advantage. 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 breathtaking turn of fortune, Goncalo Ramos grabbed a vital leveler in the final moments to send the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, stopping decisive kicks from O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, the full-back, and Desire Doue all scored successfully for PSG to seal a convincing penalty win.
The record champions PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now won this trophy for the 12th time in the past thirteen years.
