The Parisian club has now claimed the prestigious trophy on fourteen different times.
The Parisian giants required a dramatic equaliser followed by a perfect penalty shootout to overcome their arch-rivals in Kuwait and secure a record-extending fourth consecutive Trophee des Champions victory.
The European champions seemed to be coasting towards a comfortable triumph in the match between the French league champions and the Coupe de France holders after Ousmane Dembele found the scoring in the opening stages.
However, Marseille struck two times in the closing moments to take a shock lead. Initially, Mason Greenwood scored from the spot-kick, before the defender inadvertently directed the ball into his own net for an own goal.
In a breathtaking twist of fortune, Goncalo Ramos snatched a vital equaliser in the final seconds to force the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving decisive kicks from Matt O'Riley and Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and the young talent all scored successfully for Paris Saint-Germain to complete a 4-1 penalty win.
Now 14-time champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after completing a domestic double, have now lifted this trophy for the 12th time in the last 13 years.
