Ok, I'm impressed!

Is this stock or mod ROM? Reference card? 4 GB or 8 GB?
I would love to get 25~26 MH/s with ~50 watt...
Can you please help me?
Thanks

That is 45W from the GPU reading. If you add another 70W from the PCIE slot, that is 115W in total, for 130W from the wall.
I think you are refering to the older days mobo... power efficient mobo are out there ...
max eff mobo is at 35-40w... pro BTC is at 55, and what I measured , if GPU takes 45w , rest of the card should be at 40-50w. And titanium PSU will take some 5-6% from whole power ( some 50-60W if it is 1000W psu with 6 cards )....
That is right. But most people do not have the Titan, they usually have the gold with about 8-10%.
