D= i really don't want to waste my money on like some crazy power supply just to make sure it works.....which could be bad for it. If someone could even re-direct me to a site explaining power supplies good! please!

You would be fine with a 700watt+ PSU if you're going to SLI. Some say that having a powerful single +12v rail is better than having multiple rails, but make sure that you have good amperage. PC Power and Cooling makes a good power supply. Google "psu calculator" and find out how much power you'll be using, then try to find a PSU that will have that + around 20% more to give. So if you'll be using around 600watts fully loaded, you should get a 750watt PSU for the best efficiency. In other words, PSUs are most efficient when they're at about 50-80% utilization.
