The Parisian club has now claimed the prestigious cup on fourteen separate occasions.
The Parisian giants needed a dramatic equaliser followed by a perfect penalty shootout to overcome Marseille in the Gulf and secure a fourth straight Trophee des Champions victory.
The Champions League holders appeared to be sailing towards a straightforward triumph in the match featuring the Ligue 1 winners and the French Cup winners after Ousmane Dembele opened the net early on.
However, Marseille struck two times in the closing moments to seize a shock 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 breathtaking turn of fortune, Goncalo Ramos snatched a crucial equaliser in the dying moments to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving crucial kicks from O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all scored with composure for PSG to complete a convincing shootout win.
The record champions PSG, who faced last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now won this trophy for the 12th time in the past thirteen years.
