The Parisian club has now secured the season-opening trophy on fourteen separate times.
Paris Saint-Germain needed a stoppage-time equaliser followed by a successful spot-kick decider to get past Marseille in Kuwait and secure a fourth straight French Super Cup title.
The Champions League holders appeared to be coasting towards a straightforward win in the showdown between the French league champions and the French Cup winners after Ousmane Dembele opened the scoring early on.
However, Marseille struck two times late to seize a shock advantage. First, the English forward converted from the penalty spot, before Willian Pacho inadvertently 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 final moments to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, saving decisive attempts from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and Desire Doue all scored successfully for Paris Saint-Germain to complete a convincing shootout victory.
Now 14-time winners PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a domestic double, have now lifted this competition for the twelfth time in the past thirteen years.
