I have a technical question about multiple 12v rails that I can't seem to find an answer to anywhere.

If a PSU has two 12v rails at 22 A each, can both of those rails supply power the both the video card and the CPU? Or does one rail go to the CPU and the other go to the video card?

it depends on the PSU but the common set up is one rail to the CPU and one rail to everything else.
