PSG has now claimed the prestigious cup on 14 separate occasions.
The Parisian giants needed a stoppage-time leveler followed by a perfect penalty shootout to overcome their arch-rivals in Kuwait and secure a record-extending fourth consecutive French Super Cup victory.
The European champions appeared to be sailing towards a comfortable win in the showdown featuring the French league champions and the Coupe de France winners after Ousmane Dembele found the scoring early on.
Yet, Marseille fired two times late to seize a shock 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 events, Goncalo Ramos snatched a crucial equaliser in the dying moments to force the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, stopping decisive kicks from O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored successfully for PSG to seal a 4-1 penalty win.
The record winners PSG, who faced last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now lifted this competition for the 12th time in the last thirteen years.
