PSG has now won the prestigious trophy on fourteen separate times.
The Parisian giants needed a stoppage-time equaliser followed by a successful spot-kick decider to overcome their arch-rivals in the Gulf and capture a fourth straight French Super Cup victory.
The Champions League holders seemed to be sailing towards a straightforward win in the match featuring the Ligue 1 winners and the French Cup holders after the French winger opened the net in the opening stages.
However, Marseille struck twice in the closing moments to take a shock lead. Initially, the English forward converted from the penalty spot, before the defender inadvertently directed the ball into his own net for an own goal.
In a remarkable turn of events, the Portuguese striker grabbed a crucial equaliser in the dying seconds to send the match into a deciding shootout. PSG goalkeeper Chevalier then stood as the hero, saving decisive kicks from Matt O'Riley and Traore.
In the shootout, Ramos, the midfielder, the full-back, and the young talent all scored successfully for PSG to seal a 4-1 penalty win.
The record winners PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now lifted this trophy for the twelfth time in the past thirteen seasons.
