PSG has now won the season-opening cup on 14 separate times.
Paris Saint-Germain required a dramatic equaliser followed by a successful penalty shootout to get past their arch-rivals in Kuwait and secure a fourth straight French Super Cup victory.
The Champions League holders appeared to be sailing towards a straightforward triumph in the match featuring the Ligue 1 champions and the French Cup winners after Ousmane Dembele opened the net in the opening stages.
Yet, Marseille fired twice in the closing moments to seize a shock 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 remarkable turn of fortune, the Portuguese striker grabbed a vital equaliser in the final seconds to force the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, saving crucial kicks from Matt O'Riley and Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and the young talent all converted successfully for PSG to seal a 4-1 penalty victory.
Now 14-time winners PSG, who met last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now lifted this trophy for the 12th time in the past 13 years.
