Born in Luduș of Hungarian descent, Sepsi made his professional debut with CS Gaz Metan Mediaș, making 24 Liga I appearances and scoring one goal. In the 2005 summer he moved abroad, signing for Stade Rennais F.C. and being brought to the French club by compatriot László Bölöni, the team's manager.
Sepsi did not feature in any Ligue 1 matches in the 2005–06 season, only being fielded in a couple of games for the Coupe de France. Following the departure of Bölöni in the summer of 2006, he returned to Romania, joining ACF Gloria 1922 Bistrița where he impressed overall, helping them to a final sixth position in the top division and qualification to the UEFA Intertoto Cup; he was also team captain.
On 12 January 2008, Sepsi signed a five-and-a-half-year contract with S.L. Benfica from the Portuguese Primeira Liga for an undisclosed fee (newspapers reported that it could have been something between €1.8 and 2.5 million). In the summer, he was loaned to La Liga club Racing de Santander in a season-long move. He made his competitive debut with the latter on 31 August 2008, in a 1–1 home match against Sevilla FC, and contributed with 19 games – 14 starts – as the Cantabrians finished in 12th position, thus retaining their division status.
On 4 January 2010, Sepsi joined FC Politehnica Timișoara for a fee believed to be €1.2 million on a five-year deal. The club's president, Marian Iancu, revealed that the whole deal was worth €2.3 million, which included both the transfer fee value and the player's wages.
Sepsi made his debut against former team Gloria Bistrița, in a 0–0 away draw on 20 January 2010.
