The Parisian club has now claimed the prestigious cup on fourteen separate occasions.
The Parisian giants required a stoppage-time equaliser followed by a perfect spot-kick decider to get past Marseille in the Gulf and capture a record-extending fourth consecutive French Super Cup title.
The European champions appeared to be coasting towards a comfortable win in the match between the Ligue 1 winners and the Coupe de France winners after Ousmane Dembele opened the scoring early on.
Yet, the southern French side struck twice late to take a surprise lead. Initially, Mason Greenwood converted from the spot-kick, before the defender unfortunately turned the ball into his own net for an own goal.
In a breathtaking turn of events, the Portuguese striker grabbed a crucial equaliser in the dying seconds to send the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, stopping decisive attempts from O'Riley and Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted with composure for PSG to complete a 4-1 shootout win.
Now 14-time champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now lifted this competition for the 12th time in the last thirteen seasons.
