The Parisian club has now claimed the season-opening trophy on fourteen separate occasions.
The Parisian giants needed a stoppage-time equaliser 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 win in the match between the French league winners and the Coupe de France winners after Ousmane Dembele found the scoring early on.
Yet, Marseille fired twice in the closing moments to seize a surprise lead. Initially, Mason Greenwood scored from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a remarkable turn of events, the Portuguese striker snatched a vital equaliser in the final seconds to force the contest into a penalty shootout. PSG goalkeeper Chevalier then emerged as the key figure, stopping crucial kicks from Matt O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored successfully for PSG to seal a convincing penalty victory.
The record winners PSG, who faced last season's Ligue 1 runners-up Marseille after completing a domestic double, have now won this competition for the twelfth time in the past 13 years.
