The Parisian club has now secured the prestigious cup on fourteen separate occasions.
The Parisian giants needed a stoppage-time equaliser followed by a successful spot-kick decider to overcome Marseille in Kuwait and secure a fourth straight French Super Cup victory.
The European champions appeared to be sailing towards a straightforward win in the showdown featuring the Ligue 1 winners and the Coupe de France holders after Ousmane Dembele opened the net in the opening stages.
However, Marseille struck two times late to take a surprise advantage. First, the English forward scored from the penalty spot, before the defender inadvertently turned the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos snatched a vital leveler in the dying seconds to send the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping decisive kicks from O'Riley and Traore.
From the spot, Ramos, Vitinha, the full-back, and the young talent all converted successfully for PSG to complete a convincing penalty win.
The record champions PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now lifted this competition for the 12th time in the past thirteen years.
