PCIe vs 6-8 pin connectors - what's the draw priority?

Postposted on Wed Jan 09, 2013 10:59 pm

I have always wondered which supply is tapped first on a video card - Does it draw the max 75w at the motherboard first, then supplement with any extra connectors connected directly to the videocard? Or vice versa? Or does it mediate between all the connections? I was brainstorming some ideas with a motherboard that has a DC input directly in the motherboard (no 24 pin molex) and it has a max power draw of 25w on the PCIe port, and I was probing for some info surrounding the technology.
