When a PSU has dual output, traditionally one output is
isolated to the 12V connector suppling CPU power. That 12V
rail is subject to wide current swings very quickly and so
having it separate (actually not so separate, many simply
split one 12V rail with a couple of low-ohm power resistors)
isolates each 12V rail a little from the other.
