BleepingComputer.com: I Messed Up My Power Supply Installation

I recently bought a power supply to replace my one that had just burned out, and I made the mistake of failing to write the information down from the previous/burned out power supply I was trying to replace, thinking that the instructions would tell me where to plug it in at, I completely forgot that I have to write down the information, so now is my only option to take it into a computer repair store or is there anything else I can do that I don't know about? And can the repair people even fix it? or is this going to be a joy ride of seeing who can and can't fix it? Or do you think some one like geek squad can do it? And do I now stand a high risk of losing whatever was on my computer, because let's say if they plug it in wrong will that damage my files?

If you plug it in the wrong way you won't lose any data. Only one way goes in, if it is stuck then your doing it wrong.

Have you tried looking through the product manual for the new power supply unit?

In any case, the following two links should be immensely helpful to you:
