|You mean the fuse in the power supply, right? Yes.|
If it has a 115/230 voltage switch make sure it's in the correct position. DON'T GUESS and only change it with the power cord disconnected. Well, in this power supply if you want 115v, you put a 115v 2,5 A ; and if you want 240v, you put a 240v 1,5 A. So I put a 240 v, 1,5 A fuse.
If it uses the standard AT style P8 and P9 power connections, try a different PSU--if you can find one. This power supply ins't standard.
So what can I do?
