Basically I got a new power supply, but I ran to a small issue. My old PSU had a smaller cable connecting to the optical drive (at least that's what I think it's called). Anyways, the old PSU cable was smaller and my new PSU has no small cable like that. The only similar looking cable I found was way bigger. Here are some pics:
