The Parisian club has now claimed the prestigious cup on 14 separate occasions.
The Parisian giants required a dramatic equaliser followed by a perfect spot-kick decider to get past their arch-rivals in Kuwait and secure a fourth straight French Super Cup title.
The Champions League holders appeared to be sailing towards a straightforward triumph in the match between the Ligue 1 champions and the Coupe de France winners after the French winger opened the net in the opening stages.
Yet, Marseille struck twice in the closing moments to take a surprise advantage. First, the English forward 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 events, Goncalo Ramos snatched a vital equaliser in the final seconds to send the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, saving decisive attempts from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and the young talent all converted successfully for PSG to complete a convincing shootout win.
Now 14-time winners PSG, who faced last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now won this competition for the 12th time in the last thirteen years.
