You think the cards eat 320w each? Fine, whatever, believe what you want. Everyone can wait until the 8th so I can put "I told you so" in giant letters in my sig

Ugh!

because nobody raits cards like that so why believe you or some random site?
And if we are right I guess we can put we told you so "boredom 1393318".

Some random site? Wow...

Tell me how you would go about cooling a GPU that is consuming 320w with only air, please

Based on the Dailytech architecture, the 8800GTX consumes about as much as the X1950XTX. Now, the cardinal question is what 'load' constitutes. Is there any graphic utility that can properly 'load' an 8800GTX to the max? I would dare say not, given that the DX10 functionality is NOT used yet.

The main thing that puzzles me to no end though is this:

The marketing material included with the card claims NVIDIA requires at least a 450W power supply for a single GeForce 8800GTX, and 400W for the 8800GTS…GeForce 8800 cards in SLI mode will likely carry a power supply "recommendation" of 800W. NVIDIA's GeForce 7950GX2, currently the company's top performing video card, carries a recommendation of 400W to run the card in single-card mode.
http://hardware.gotfrag.com/portal/story/34814/
Why would 450W for one card be enough and 800W be required for SLI? What am I missing?

Given the 450W recommendation for a single card, and 800W for SLI, I think there are certain functionalities that cannot be used by a single card (just like certain types of AA that can only be used in Crossfire with X1900's). The 350W hike seems a lot, indicating that the additional card DOES require a lot of power. However, nVidia probably takes into account that a good 450W PSU has like ~32A on the 12V Rails and that a 800W might only have ~50A or so (quality ones will have more, but it might be nVidia plays it safe)

Because theya re taking into account the power required for the rest of the system.

ie. 250W for gpu:

200 (sys) + 250 = 450

BUT 200+ 250 + 250 (SLI) = 700W

It doesn;t double. Thats my thoery.

I'm not sure either? Boredom seems to know quite a bit.

I'll be waiting for your sig update.

all I know is the nvidia clames the current nvidia cards pull around 120w peak "per card" and these newer cards are twice as powerfull. hmmm makes me wonder..
post #89 of 122
I meant that 800W seems high to me... not low. I would have expected 650W or so.

And you don't tell me that nVidia only reserves 200W for the rest of the rig...

Likely, the cards will draw around ~200W a piece when really fully loaded.... I don't think that there is any application yet that gives those guys a real workout.

If that's true, you'd better make sure that you have a quality 450W unit with sufficient amps on the 12V rails. If the card indeed draws 200W, that's nearly 17A on the 12V rails for the card alone. If the rest of the rig then indeed draws 200W, that's another, say, 13A on the 12V rails (plus a bunch of amps on the other rails).

However, it's all speculation for now....

After going on that rant I hope I'm right or I'm going to look like quite the idiot...

I probably am right though, as I don't see how they can measure the rig consumption from the outlet and somehow differentiate between what is consuming what
