The Parisian club has now claimed the season-opening cup on 14 different times.
The Parisian giants required a dramatic equaliser followed by a perfect penalty shootout to overcome Marseille in Kuwait and capture a fourth straight French Super Cup victory.
The European champions appeared to be coasting towards a comfortable win in the match featuring the French league champions and the Coupe de France holders after Ousmane Dembele opened the net in the opening stages.
However, Marseille struck twice in the closing moments to seize a surprise lead. First, the English forward scored from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own goal.
In a remarkable twist of fortune, the Portuguese striker snatched a vital leveler in the dying moments to force the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, stopping crucial attempts from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted successfully for PSG to complete a 4-1 penalty win.
The record champions PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now won this trophy for the twelfth time in the past thirteen years.
