Geforce 6600 GT

Hi there, earlier today I got a new GF6600 GT card and now when I play CoD2 on my comp it says that the card isn't getting enough power and that the card has reverted to a lower setting in order not to damage the card. I have the extra powersupply cable plugged into the card and my power supply is a 650 Watts Sweex. So power should be the least of my problems, anyone that has some idea of what might be wrong or what I can do to fix it?

You need to make sure your 12v rail is both stable, and has enough amps on it. Just because you have a high watt powersupply, if the 12v rail doesnt have enough amps for all your peripherals to draw off of, then ur gonna get instability, and possible problems like stated above. I *think* you need atleast 30a on the 12v. U might just need a new PSU.
