PSG has now won the prestigious trophy on fourteen separate times.
Paris Saint-Germain needed a dramatic equaliser followed by a successful spot-kick decider to get past their arch-rivals in Kuwait and secure a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders appeared to be sailing towards a comfortable triumph in the showdown featuring the French league winners and the Coupe de France holders after Ousmane Dembele opened the scoring early on.
Yet, Marseille fired twice late to take a shock lead. Initially, Mason Greenwood scored from the penalty spot, before the defender inadvertently turned the ball into his own net for an own-goal.
In a remarkable turn of events, Goncalo Ramos grabbed a vital equaliser in the final seconds to send the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving crucial attempts from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all scored successfully for Paris Saint-Germain to complete a convincing penalty victory.
Now 14-time champions PSG, who met last season's Ligue 1 runners-up Marseille after completing a domestic double, have now won this competition for the 12th time in the past 13 years.
