This is just a quick tutorial on how you can test your PSU to see if it is DOA and also to see if it is healthy. In my case I installed my PSU and it started for a split second and I knew something was wrong so I decided to test it by inserting a wire into the 4th wire (green) from the right and ground it to the black wire next to it and not to my surprise it started for a split second here as well and then went flat dead.
If you have any questions please let me know and also don't forget to be VERY CAREFUL when handling a PSU (especially if you have turned it on before).
