The Parisian club has now secured the season-opening trophy on 14 separate occasions.
The Parisian giants required a stoppage-time equaliser followed by a perfect penalty shootout to get past Marseille in Kuwait and secure a fourth straight Trophee des Champions title.
The European champions seemed to be coasting towards a straightforward triumph in the match featuring the Ligue 1 champions and the Coupe de France holders after the French winger found the net early on.
However, Marseille struck two times late to take a shock advantage. Initially, Mason Greenwood converted from the spot-kick, before the defender inadvertently turned the ball into his own net for an own goal.
In a remarkable twist of events, the Portuguese striker snatched a vital leveler in the final seconds to send the match into a deciding shootout. PSG goalkeeper Chevalier then emerged as the key figure, saving decisive kicks from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored with composure for Paris Saint-Germain to complete a 4-1 shootout win.
The record champions PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now won this trophy for the 12th time in the last 13 seasons.
