Micro ATX PSU Troubles

[Tralius]

Hey,
I am currently using a micro ATX PSU 240W power supply for my portable xbox 360 but yesterday the 3.3v and ground shorted together by mistake. Now i have no outputs from the power supply. Ive had a look and checked the main fuse and thats fine, but it definatly sounds like a fuse problem as I can still hear the small electrical sound you get when you plug things in. Also, the fan isnt spinning. Is this just a fuse that I can't find or is the PSU now dead?
Thanks

I dont know what to tell you, usually with normal ATX power supplies you just unplug them, wait a second, and it works again.

Unless the short still exists.
