PSG has now claimed the season-opening trophy on fourteen different occasions.
The Parisian giants required a dramatic equaliser followed by a successful spot-kick decider to get past their arch-rivals in the Gulf and capture a fourth straight French Super Cup title.
The Champions League holders seemed to be sailing towards a comfortable win in the match featuring the French league champions and the French Cup holders after the French winger found the scoring early on.
Yet, Marseille fired twice in the closing moments to take a surprise advantage. First, Mason Greenwood converted from the penalty spot, before the defender unfortunately turned the ball into his own net for an own-goal.
In a breathtaking turn of fortune, Goncalo Ramos snatched a crucial leveler in the final moments to send the match into a deciding shootout. The Parisian shot-stopper Chevalier then stood as the key figure, stopping decisive kicks from Matt O'Riley and Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and the young talent all converted with composure for PSG to complete a 4-1 penalty victory.
The record champions PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a domestic double, have now won this competition for the 12th time in the past 13 years.
