PSG has now won the season-opening trophy on fourteen separate occasions.
Paris Saint-Germain needed a stoppage-time equaliser followed by a perfect spot-kick decider to get past Marseille in the Gulf and capture a fourth straight French Super Cup victory.
The European champions appeared to be sailing towards a straightforward win in the match featuring the French league winners and the French Cup winners after the French winger opened the scoring early on.
However, the southern French side fired twice late to seize a shock lead. 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 breathtaking turn of events, Goncalo Ramos grabbed a crucial leveler in the dying moments to send the match into a deciding shootout. PSG goalkeeper Chevalier then emerged as the key figure, saving decisive attempts from O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, the full-back, and Desire Doue all scored successfully for PSG to seal a 4-1 penalty win.
Now 14-time champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now lifted this competition for the 12th time in the last thirteen years.
