I know there is secondary PSU's being made to
supplement main PSU power to video
cards but don't know if it takes specially wired PSU's
to allow them to work in tandem.
From a 12V rail standpoint I'd assume you'd want to
be feeding it from 2 separate
rails assuming 16A/rail so you don't tax one rail.
Looks like the Sapphire version
shipped with a molex splitter but again I'd be worried
about taxing a single rail.
Given the power requirements of a modern cards,
vendors should be more explicit
stating their power breakdown by bus & number of
rails. Seems hard to find, from what
I seen looking around, to find the total amps needed
never mind a breakdown of what's
being drawn from where.
