OK, I think I got it figured out. My total wattage use for my rig (even though it doesn't have the processor I have) was 305. That's including the PCI-E Video Card, but, to be honest, I don't think this really helps me when getting one, but then again, it might. I've been looking at cards on Newegg, and a lot of them say to have a 6-pin 75 watt connecter, but with a recommended PSU of being like 400, 450+. So, would that mean that I wouldn't really need a 400+ watt PSU as long as I have a 75 watt 6-pin connector? I found what seems to be a good ATI based card for a reasonable price that is in my range, but are asking for 400+ watt PSU's with a 75 watt 6-pin connector.
Thanks for the help again.
