I'm speechless. Thank you Alexey, it's a GREAT article. Everything should be clear now about GPU power consumption in different scenarios.

THANK YOU. ^^

Seems like the timing on this article is a bit off. I hope it will be updated in a few days.

As soon as we'll test some GeForce 400's.

Amazing review, thanks! What seems odd for me is this... In the power consumption section of the review, the load power on both the ATI card and the nVidia card is higher on the 6-pin connection, rather than the 8-pin. I thought the 8-pin was added to the ATX specification to allow higher power consumption of graphics cards, right!?! If so, then why is the 6-pin drawing more power than the 8-pin connection? Is there a labeling mistake, or are we getting ripped off or mislead regarding the 8-pin connector requirement???

I don't see the point. Look, for example, in Crysis Warhead, Radeon HD 5970 eats up to 12A on 8-pin connector, but only about 6A on 6-pin one. So do GeForce GTX 295.

So your two "power lines current" graphs at the end of your article must be mislabeled. You have the red lines labeled "6-pin" and the orange "6/8-pin" and the red line is always higher than the orange. It makes sense now that I compare it to the tables, which seem to be correct.

Perhaps, it would be better to rename labels to "1-st" and "2-nd". See, "6/8-pin" cable from measurement board was connected to 1-st 6-pin connector on each card. That's why it caused confusion. In both cases, second connector was loaded much more heavily.

Got it. Thanks for the clarification.

I think the reason is that it most cases 6/8-pin connector is a second 6-pin and not 8-pin. Only the dual CPUs have 8-pin connectors I asume.
Vader, is it possible to list the power connectors for each card in the methodology page to avoid the confusion?

Except for GeForce GTX 295 and Radeon HD 5970, they all carry two 6-pin connectors on-board.

Well power consumption for these cards is widely known, not so precisely, but still. I'd be interested of a roundup of consumption with two LCDs, because its very different than with just one, particularly in idle.

Hi, i've been wondering for a long time for the 5770 crossfire power usage watts and 12v consumption, for there's alot of sayings about this in alot of forums and cant find the real answer!!!
Thanks alot!
