PSU not working

[Augustine4777]

I tried to build a new pc using my old components on my new motherboard. I tried it once without a case then replaced every compnent back to my old pc and all was fine. Now I recently I bought a new case Armaggeddon T300 and did the same connections I did last time but didn't work. Now I'm trying to piece together the old pc to its original case but the PSU doesn't want to start or even make a small attempt to on. What's wrong with my old pc?
