PSG has now won the prestigious trophy on 14 different occasions.
Paris Saint-Germain needed a stoppage-time equaliser followed by a successful spot-kick decider to overcome Marseille in Kuwait and secure a record-extending fourth consecutive French Super Cup title.
The European champions seemed to be coasting towards a comfortable win in the showdown between the Ligue 1 winners and the Coupe de France winners after Ousmane Dembele found the scoring early on.
Yet, the southern French side struck two times in the closing moments to take a surprise advantage. First, the English forward converted from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a breathtaking twist of fortune, the Portuguese striker grabbed a crucial leveler in the dying seconds to send the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, stopping decisive attempts from O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, the full-back, and the young talent all converted with composure for PSG to seal a 4-1 shootout victory.
Now 14-time winners PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now lifted this competition for the 12th time in the last thirteen seasons.
