PSG has now claimed the prestigious trophy on 14 separate occasions.
Paris Saint-Germain needed a stoppage-time equaliser followed by a perfect penalty shootout to get past Marseille in the Gulf and capture a record-extending fourth consecutive French Super Cup victory.
The European champions seemed to be sailing towards a straightforward triumph in the match featuring the French league winners and the Coupe de France holders after the French winger found the net in the opening stages.
However, Marseille fired 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 twist of fortune, Goncalo Ramos snatched a vital leveler in the final moments to force the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, stopping crucial kicks from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and the young talent all scored with composure for Paris Saint-Germain to seal a convincing shootout victory.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now lifted this trophy for the twelfth time in the last thirteen years.
