When crunching and folding with my GTX 1070, the power draw is about the 300 to 310w marker.. It's not too bad as it also has 16 threads crunching away, with a 2700X installed
It's not a bad system at all
(Very far from tweaked in anyway shape or form mind....)
Same thing on my main gaming rig, 3900X + 2 1080 Ti's, that's pulling double the watts but it's producing about 3 to 4 times the points for the day, so that's not a bad thing at all in my eyes
I test all of my rigs and I'm still waiting for 10 minutes where it's not 1am and I need sleep to put up some wattage usage for everyone!
I guess it's like a car analogy.... You have a Prius and drive it flat out, it'll drink fuel in comparison.. Have something like a M3/S4 etc. and follow the Prius doing the same thing, the M3/S4 will be more efficient because it's built for it.. I guess in a way the same can be said for the higher end GPUs... Yes they are hugely expensive and even more so with the RTX 2070/80/Ti versions, but they'll pull a little more power but get the job done in much less time
Another reason for always over spec'ing your GPU/CPU in a build in my head....
Whatever do I know??
(here's the Top Gear vid from the UK I got the analogy from...
Top Gear - M3 v Prius...
I tend to pause FAH if it doesn't find a work unit for about 5 mintues, then leave it an hour before I pause it for the last time and leave it a couple hours (it's doing WCG as well at the same time...) If it doesn't download a work unit, FAH just gets turned off and I just crunch for our WCG team
I don't crunch 24/7 mainly due to the power consumption of all my crunchers put together, my word I'd have a heart attack when I would look at the electric bill... I only tend to run everything when the solar panels are working nicely and are giving out about 1000w to 1500w... If anything over 2000w is being made, everything is on and I have another working away now for Rosetta so without solar I'd never be even close to what I can put out that's for sure!!
