The wattage dropped from 380 to 280 on the computer with tweaks, the device is very accurate, and my power bill is a lot less.
So I have to include that it is accurate.
*2X 6870 computer: 380>280*
*2X 6950 computer: 430>330*
How ever It is actually 30 watts per card, and 40watts for CPU.
I did made an error about 42.5 watts.
I measured about 3 times, tried back and forth, etc.
Device I am using.
I was thinking of making a Savinghardware site, instead of a mining hardware one.
Where people can post there numbers on how much watts they saved using a device like mine, or similar.
Maybe someone can make this site, and I can post all my numbers.
I can post my 2X6770, 2X6870, 2X6950.
And I can post three different cpus as well.
It would be interesting to have a site like this.
