Thank you!

Hi everybody.
I need help!
I have just bought a new PC (I couldn't play with my old laptop) and I have found my old but still good Sidewinder Force Feedback Wheel. just one problem: I have no more its power supply and that means no force feedback!

Anyone has it?
People who has it can please tell me electrical output info of its power supply so that I can find a compatible one.
Please please please
Bye bye
