SLI Power Consumption

6800 Ultra's SLI Peak Power Consumption: 329W

Just found this review and found these numbers to be outrageous need a seperate PSU just for the video cards. This is also with stock speeds and no vmods.

Well this should be a real eye opener then because I figure the data is about 15-20% LOWER than actual power consumption based on the accuracy of the shunt method used in the article...

You'll need enough power to do arc welding to run an SLI system!

Yea those results do seem low, according to that the 6800 Ultra uses less watts that a AMD64 by 10W, and I think that is just utterly wrong,

so what? a ferrari gets 6 miles per gallon when your being nice, and 1-2mpg when your on it, performance comes at a cost, 2 cpu's (intel) are gona cost you another 300watts when your in high gear, and relly now, who isnt? you could save yourself a few watts and get a AMD or even better wait for the dual opteron SLi board! thats gona cost you about 180-220 watts, so you up to 500 watts already, get the CM stacker and give yourself 2 psu's, problem solved...

personaly im waiting for a good dual xeon sli board to come out before i convert, or maybe even a 478S/776S board. hell i love my dual 250/250 systems at work id take a couple of opterons pray for O/C ability...

Those are pre overclock power usuage. Multiply that by 1.5 for "light" over clock or 2x for super duper heavy overclock on a system full of stuff such as HDD, fans, etc. Now we are approching dangerous limit on majority of PSU out there. For me, I am not worried with zippy 700W :)

nor am I worried about my pcp&c 510 deluxe :) (really a zippy)

i think my OCZ 520 is up to the job (might buy the 600 though, for :banana::banana::banana::banana::banana:s and giggles)

the problem it appears is that if we have a dual SLi board its gona need a 24pin psu plug, and the GPU's are going to need 2 psi express power plugs, right?
