PSG has now secured the prestigious trophy on 14 separate occasions.
Paris Saint-Germain needed a dramatic equaliser followed by a perfect spot-kick decider to get past Marseille in the Gulf 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 French league winners and the French Cup winners after the French winger opened the net in the opening stages.
However, the southern French side fired twice in the closing moments to take a shock advantage. Initially, the English forward scored from the spot-kick, before the defender unfortunately turned the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos snatched a vital leveler in the final moments to force the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, saving crucial attempts from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and the young talent all converted successfully for PSG to complete a convincing shootout win.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now won this trophy for the 12th time in the past 13 years.
