The thing is that i don´t want to overload a rail, because like it explains here:
"Typical multiple +12V rail configurations:
2 x 12V rails
Original ATX12V specification's division of +12V rails.
One rail to the CPU, one rail to everything else.
VERY old school since it's very likely that "everything else" may include a graphics card that requires a PCIe connector.
Typically only seen on PSU's < 600W."
Can i run "everything else" and a video card like the hd 6950 with that rail of 18amp? I may sound like flying around in the same thing too much but I want to be pretty sure about this,
