I was worry about the amps the card could be using since each of the 4 12v rails have 18 amps, i was kinda thinking on how to connect them in a safe way, atm i have video card connected in the main rail coming from the psu (2 6+2pin pcie), without using the extra two, the number 3 (6pin pcie) and 4 (6pin pcie) 12v rails that the psu has, the rail number 2 is used for the case fan hard drives and dvd burner, anyway i guess how i have it connected works so i guess i will continue using it that way, thanks for the reply
