The Parisian club has now secured the prestigious cup on 14 different times.
The Parisian giants needed a stoppage-time leveler followed by a perfect spot-kick decider to get past Marseille in Kuwait and capture a fourth straight Trophee des Champions title.
The European champions seemed to be sailing towards a straightforward triumph in the match featuring the Ligue 1 champions and the Coupe de France winners after the French winger opened the scoring in the opening stages.
Yet, Marseille struck twice in the closing moments to seize a surprise advantage. First, Mason Greenwood converted from the spot-kick, before the defender unfortunately directed the ball into his own net for an own goal.
In a remarkable turn of fortune, Goncalo Ramos snatched a vital equaliser in the final moments to force the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving decisive kicks from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, the full-back, and the young talent all converted successfully for Paris Saint-Germain to complete a convincing penalty victory.
The record winners Paris Saint-Germain, 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 13 years.
