Hi Arun,

If you are thinking about modifying your existng PSU, don't bother. You can buy a cheap PSU from the usual electrical/electronics people for a modest price.

Outputs and pinouts can be found at:

If you are unsure whether a model will work, post a link here and smarter people than me will be able to advise.
