UPDATE!!!
OK so i have my 550W power supply, look at my 1st post for more details. An I put an 8ohm resistor on it rated at 20w. This resistor get HOT!!! wooo. So what I plan on doing is getting another 8ohm resistor and put it in parallel with the one i have now giving me 4ohm. Maybe the added resistor will cool it down. I had to get an 8 ohm cause Radio Shack here didn't have anything lower.
Anyway running setup tests now and hopefully by tomarrow i'll have the rig together.
Question: How do I measure how much current is being drawn????
