Okay thanks that helps, I never really worried about how I connected things up before and with having all these rails, and the box saying power supply needed to have 40A on the 12V rail everything was so vague. I have the Real Power Pro 1000W btw. Thanks for the help though.
So I'm a little confused on how I should connect the power suppply to my video card with these 6 rails. Just got a Real Power 1000W, GTX280 says it needs 40A on the rail, so since rails 3 and 4 say they are rated at 28A should I connect the 6 pin PCI-E power connecters from the other rails on the card also instead of 8pin+6Pin on the same rail? Thanks
