PSG has now won the season-opening cup on 14 different occasions.
Paris Saint-Germain needed a dramatic equaliser followed by a successful spot-kick decider to overcome Marseille in Kuwait and secure a fourth straight French Super Cup victory.
The Champions League holders seemed to be coasting towards a straightforward win in the showdown featuring the French league winners and the French Cup winners after Ousmane Dembele opened the scoring early on.
However, Marseille fired twice late to seize a shock advantage. First, Mason Greenwood converted from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own goal.
In a remarkable twist of events, the Portuguese striker snatched a vital equaliser in the final seconds to force the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, stopping decisive attempts from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, the full-back, and Desire Doue all converted with composure for PSG to complete a convincing shootout win.
Now 14-time champions PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now won this competition for the 12th time in the past thirteen years.
