800W, we touching exotic cooling levels of power draw here folks!

I mean, if Nvidia can do 575w with a 2 slot blow through with just a wicking vapour chamber, i think it stands to reason a 3 slot version of the card could do 800w, but who knows. The gains in cooling efficiency of good ol' HSF design has been blowing my mind in the last couple years.

At that point the card should be coming with a dedicated power supply and external cooler.

At the same time, I am also blown away by the power draw of high end cards. Gone are days when you had 350W as the top end limit.

Did hwbusters do any transient load test for 1250w + PSU with 2 HVPWR connectors?

Maybe the prototype uses 800W, there's no way a 10% boost to CUDA cores and slight memory speed bump would require an additional 225W or 40% increase in TDP for a retail product.
