Power supply connection questions

[silverwolf0]

Right now I am having problems with my dvdrom drive not being able to go past udma2, having a really slow transfer speed, and giving me a blue screen after a while of use. I have an irksome feeling it is my power supply and that I did something stupid with the modular connectors. I have an antec NeoHe 430watt that came in my p150 and has modular connectors. There are three connectors so far:

1. Goes straight to an sata hard drive.
2. Goes from my dvdrom 4 pin, zalman vga cooler v700alcu thats connected to the middle of the connector 4 pin with an accompanying adaptor that has 4 connectors sticking out for 5v and 12v, and at the end of the original connector is a 120mm tricool fan that has an attached fan speed changer on it.
3. Connects directly to floppy drive, end is 4 pin with an adapter to the other 4 pin thing for hte floppy.

Number 2 worries me. What are the constraints of connecting too many items at once? Doe sthe whole connector still run 12V when I change fan speed or connect it to the vga cooler? I am a PSU noob. I didn't have any problems before because all my PSU's weren't modular but this one is and I think it might be causing my problems. Thanks in advance.

The best way to answer this question is to mess with the connections and see if removing 1 or 2 devices solve the problem. If yes, then try to plan how to spread it on other connectors.

I was planning on trying that but I was hoping there was some kind of methodology to it like "you must connect x with x but don't connect y on the same line". My case is rather cramped and want to do it the first time around. I am not a hardware person.
