The Parisian club has now secured the prestigious trophy on fourteen separate occasions.
The Parisian giants needed a dramatic equaliser followed by a successful penalty shootout to overcome Marseille in the Gulf and capture a fourth straight French Super Cup victory.
The Champions League holders appeared to be coasting towards a comfortable win in the showdown between the Ligue 1 winners and the Coupe de France winners after Ousmane Dembele opened the net early on.
However, Marseille fired two times late to seize a surprise lead. First, the English forward converted from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a remarkable twist of events, Goncalo Ramos snatched a vital equaliser in the dying seconds to send the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, saving crucial attempts from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all scored successfully for PSG to complete a 4-1 shootout victory.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now won this trophy for the 12th time in the last 13 years.
