The Parisian club has now won the prestigious trophy on 14 separate times.
The Parisian giants needed a stoppage-time equaliser followed by a successful penalty shootout to overcome Marseille in the Gulf and capture a record-extending fourth consecutive French Super Cup title.
The Champions League holders seemed to be sailing towards a comfortable triumph in the match featuring the French league champions and the Coupe de France holders after Ousmane Dembele opened the net in the opening stages.
Yet, the southern French side fired two times in the closing moments to seize a surprise lead. Initially, Mason Greenwood converted from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a remarkable turn of events, the Portuguese striker snatched a vital equaliser in the final seconds to send the contest into a deciding shootout. PSG goalkeeper Chevalier then emerged as the key figure, saving crucial kicks from Matt O'Riley and Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored with composure for PSG to seal a 4-1 shootout win.
The record champions PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now lifted this competition for the 12th time in the past 13 years.
