Also I dont think it's a connection problem because everything lights up and it does the exact same thing as with the old power supplyI went ahead and edited your post with your original thread. I'm not sure why you felt the need to make a new thread with all the original content. You could have just posted in the first thread that the new PSU didn't fix it.
You said things don't light up, so my first suggestion is to double check all the PSU connections. You have a modular PSU so make sure you are using the correct cables in the correct spots and everything is tight. On BOTH ends. I dislike modular PSUs for this reason.
