PSG has now won the season-opening cup on fourteen separate occasions.
The Parisian giants required a dramatic equaliser followed by a successful spot-kick decider to overcome their arch-rivals in the Gulf and capture a record-extending fourth consecutive French Super Cup victory.
The European champions seemed to be coasting towards a comfortable win in the match between the French league champions and the Coupe de France holders after the French winger opened the net in the opening stages.
However, Marseille fired two times in the closing moments to take a surprise lead. First, the English forward scored from the penalty spot, before the defender unfortunately turned the ball into his own net for an own-goal.
In a breathtaking turn of events, the Portuguese striker snatched a crucial equaliser in the dying moments to send the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, saving decisive attempts from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and the young talent all converted successfully for Paris Saint-Germain to seal a convincing shootout victory.
The record champions Paris Saint-Germain, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now lifted this trophy for the twelfth time in the last 13 years.
