The Parisian club has now secured the season-opening trophy on 14 separate times.
The Parisian giants needed a dramatic equaliser followed by a perfect spot-kick decider to overcome Marseille in Kuwait and capture a record-extending fourth consecutive French Super Cup title.
The European champions appeared to be coasting towards a comfortable triumph in the showdown featuring the French league winners and the French Cup winners after Ousmane Dembele opened the net early on.
Yet, Marseille fired twice in the closing moments to seize a surprise advantage. Initially, the English forward converted from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a breathtaking turn of events, Goncalo Ramos snatched a vital equaliser in the dying moments to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping crucial attempts from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and Desire Doue all scored successfully for PSG to complete a convincing shootout victory.
The record 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 12th time in the past 13 seasons.
