Paksi Sportegyesület, usually known as Paksi SE and sometimes shortened to Paks, was first established in November 1952. The team are nicknamed 'Atomcsapat', which translates to 'Nuclear Team', because the city of Paks houses Hungary's only nuclear power. Paksi SE have gradually climbed through the country's league system and are notable for being the only side to exclusively field Hungarian footballers.
For several years after the club's foundation, Paks played their football at county level. In 1970, the side won the county championship and gained promotion to Hungary's third division. In 2001, they were crowned third division champions and rose up to the second divison. They went on to win that league in 2006, in order to gain promotion to the top tier for the first time in the club's history.
Since arriving in the top division, Paksi SE have gone on to achieve significant success. In the 2009–10 season, they were runners up in the Ligakupa, losing in the final to Debrecen. The following year, the team built on this cup run and achieved a remarkable second place finish in the league. In addition, they claimed their first major domestic honour, as they once again reached the Ligakipa final and this time triumphed over the same opponents from the previous year, Debrecen. As a result of their performances over the campaign, they gained entry into the following season's UEFA Europa League.
A number of full and youth Hungarian international footballers have represented Paks over the years, with some of the most notable examples including Dániel Böde, Gábor Vayer and Norbert Heffler.
The team play their home matches at Stadion PSE, which is able to hold a maxium of 5,000 supporters. The stadium does not currently meet UEFA requirements for continental competitions. Therefore, Paksi SE play their European matches at Sóstói Stadion, which is able to hold 14,300 spectators.
