Örebro had a chance to take the lead from the penalty spot after a quarter, but talent Jake Larsson's penalty was saved by Lukas Jonsson in the Sirius goal.
Yet it was the guests who took the lead. 37 minutes into the match, Robin Book managed a counterattack, but Sirius's shot sailed wide after his break down the right.
The receipt came shortly after the break when Stefano Vecchia, who jumped into the break, leaned forward. His recording then took on Örebro's Finnish defender Albin Granlund who set his own goalkeeper.
After the goal, there was a long interruption in the match as the digital billboard around the plan collapsed and it made it a full 12 extra minutes.
The victory came through Yukiya Sugita in the 67th minute. He ended a neat attack with a distinct shot that went in behind Oscar Jansson.
It was also the last goal of the match and the Uppsala team got to celebrate in the rain over the new Students.
Sirius is therefore second in the Allsvenskan, two points behind leading IFK Norrköping, while Örebro stands in a win and a 13th place.
