Yes, but they were limited production cards like the ASUS Mars that exceeded 300W by quite a bit
This is the first card in years to show something that may potentially exceed the PCIe spec (since 6-pin+8-Pin is PLENTY for the 300W spec).
Of course there is precedent; wasn't there a voodoo card with a power brick? But this is the first AMD or Nvidia card to use 8-pin+8-pin since the PCIe 2.0 spec came out.
i will predict that you guys are going to be surprised ... make that *shocked*
- you will may have your first WtF moment re: HW in a long time (<<<My prediction)
When was the last time you read something about HW and said WtF (in a good surprised way)?
And something else to consider .. AMD fans have always made a POINT about how much their cards conserved power. What do they say now about an 8-pin+8-pin card?
It could be worse?
