PSG has now won the prestigious trophy on 14 different occasions.
The Parisian giants needed a stoppage-time leveler followed by a perfect penalty shootout to get past Marseille in Kuwait and capture a fourth straight Trophee des Champions title.
The European champions appeared to be coasting towards a straightforward win in the match featuring the French league champions and the French Cup holders after Ousmane Dembele opened the net in the opening stages.
Yet, Marseille struck two times in the closing moments to take a shock advantage. Initially, Mason Greenwood scored from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a breathtaking turn of fortune, Goncalo Ramos snatched a vital leveler in the final seconds to send the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, saving crucial kicks from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all converted with composure for PSG to complete a 4-1 shootout victory.
The record winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now lifted this trophy for the 12th time in the last thirteen seasons.
