The Parisian club has now claimed the prestigious cup on 14 different occasions.
Paris Saint-Germain needed a dramatic equaliser followed by a perfect penalty shootout to get past Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions victory.
The European champions seemed to be sailing towards a straightforward triumph in the match between the French league winners and the Coupe de France winners after the French winger found the scoring early on.
However, Marseille struck twice late to take a surprise lead. Initially, Mason Greenwood converted from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a breathtaking turn of fortune, the Portuguese striker snatched a vital equaliser in the dying seconds to send the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, saving crucial attempts from Matt O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted with composure for PSG to seal a 4-1 penalty victory.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now won this competition for the 12th time in the past thirteen seasons.
