PSG has now secured the season-opening trophy on 14 separate occasions.
The Parisian giants required a stoppage-time equaliser followed by a successful penalty shootout to overcome their arch-rivals in Kuwait and secure a fourth straight French Super Cup title.
The European champions appeared to be coasting towards a straightforward triumph in the showdown between the Ligue 1 champions and the Coupe de France winners after the French winger found the net in the opening stages.
However, Marseille fired two times in the closing moments to take a surprise advantage. First, the English forward converted from the spot-kick, before the defender inadvertently directed the ball into his own net for an own goal.
In a remarkable twist of events, the Portuguese striker snatched a vital equaliser in the final seconds to force the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, stopping decisive attempts from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all converted successfully for PSG to complete a 4-1 penalty win.
The record champions PSG, who met last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now won this competition for the 12th time in the last thirteen years.
