Armando Broja scored the opening goal for Saints in his debut, and then added another against Newport.
Southampton scored the largest away win in their history, beating Newport County 8-1 at Rodney Parade.
Saints were dominant at the break and led 3-0 thanks to Armando Broja's debut goal and further goals from Nathan Tella, Kyle Walker-Peters and Kyle Walker–Peters.
After the break, Mohamed Elyounoussi scored a double. Broja soon added a sixth.
Nathan Redmond's exact finish made it 7-1 before Elyounoussi scored his third goal with nearly the last kick.
This tie in the EFL Cup was their largest post-war win. It was also the largest road victory in Southampton's 135 year history.
Newport has an exceptional pedigree in recent cup competitions. Southampton was the ninth team from the top flight that the Exiles have faced. However, they didn't get out of first gear on what was a terrible night for them.
Saints boss Ralph Hasenhuttl selected a strong team for Newport's home opener. Newport's notorious playing surface had been re-used over the summer and it was a perfect surface for Saints.
When Nathan Redmond's long-range attempt was tipped onto Nick Townsend's crossbar, the visitors took the lead. However, ex-Chelsea forward Broja managed to score from close range.
Saints were 2-0 ahead after Redmond's clever pass allowed Elyounoussi to be freed. Tella was able to get home in slot fashion.
Redmond missed an opportunity to make it 3-0, but Walker-Peters made it 3-0 before the break with his angled shot that beat Newport goalkeeper Townsend at the near post.
Elyounoussi prodded the ball home from close range shortly after the break, after more Saints pressure. He added another just before the hour mark, after two years of being absent from the club.
Broja scored his second goal on his debut. Redmond added to the record with two smart goals.
Newport's veteran Kevin Ellison missed the mark as Newport tried to get a late consolation. But Saints won the last battle as Elyounoussi got his third goal in the dying minutes.
Wayne Hatswell, Newport County assistant manager, said:
"It was a hard lesson, and that was because of the team we were up against. They are confident when they have the chance to do what they love.
"Fair play Ralph, he brought an extremely strong team and I cannot praise Southampton enough for how professional they were.
"They were relentless in following us up the pitch, and we could see the difference in the quality.
"We could have stopped some of their goals, and I am disappointed in that, but we must get up. This is not going to be the end of our season playing Southampton.
Ralph Hasenhuttl, Southampton boss, said:
"This was a well-deserved win. This was a serious performance, and that is what you need to beat a lower-league club.
"To score three goals so quickly allowed us to push and maintain a high tempo, which enabled us to score many goals.
"We had many different scorers. This is what we need: more goal scorers.
It's not an easy task. It's important to take the task seriously and create a plan. It was quite easy. Many teams have failed here in the past."
