The Parisian club has now claimed the prestigious trophy on 14 separate occasions.
Paris Saint-Germain required a stoppage-time leveler followed by a perfect penalty shootout to get past Marseille in Kuwait and secure a fourth straight Trophee des Champions title.
The European champions appeared to be sailing towards a straightforward win in the match between the French league champions and the French Cup holders after the French winger found the net early on.
However, Marseille fired two times in the closing moments to take a shock advantage. First, the English forward converted from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own goal.
In a breathtaking turn of fortune, the Portuguese striker grabbed a vital leveler in the final seconds to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, stopping crucial kicks from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and the young talent all scored successfully for Paris Saint-Germain to seal a 4-1 penalty victory.
The record champions PSG, who met last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now lifted this competition for the 12th time in the last thirteen years.
