The Parisian club has now won the prestigious cup on 14 separate times.
Paris Saint-Germain required a stoppage-time equaliser followed by a perfect penalty shootout to get past Marseille in Kuwait and secure a record-extending fourth consecutive French Super Cup title.
The Champions League holders seemed to be sailing towards a straightforward triumph in the showdown between the Ligue 1 winners and the Coupe de France winners after the French winger found the scoring early on.
However, Marseille struck two times late to take a surprise lead. First, Mason Greenwood scored from the penalty spot, before the defender inadvertently turned the ball into his own net for an own-goal.
In a breathtaking turn of events, Goncalo Ramos grabbed a crucial equaliser in the dying seconds to send the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, stopping crucial kicks from O'Riley and Traore.
From the spot, Ramos, the midfielder, the full-back, and the young talent all scored with composure for PSG to complete a 4-1 shootout victory.
The record winners PSG, who faced last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now lifted this trophy for the 12th time in the past 13 years.
