Nvidia Refresh Rate Power Consumption Bug Is Back - SteelCrysis - 03-08-2016

Quote:While this "power bug" may sound like a minor issue, its effects are more insidious than one might expect. Using our trusty Watts Up power meter, I measured the idle power consumption of our testbed system at the wall. When the GTX 980 Ti is running at 135MHz as expected, that system draws between 80 and 90 watts at the wall. Kick up the refresh rate in a multi-monitor setup, though, and that figure jumps to between 130 and 150 watts. An affected PC running 24/7 is nearly doubling its idle power consumption, and that'll make for a hefty increase in one's power bill. Even weirder still, this problem doesn't seem to go away even if you turn off all of the monitors attached to the PC.
We tested some other parameters and found that display resolution and G-Sync settings don't appear to have any effect on the issue. We've reported our findings to Nvidia, and we'll update this post if we hear back. Hopefully, this bug can be solved with another simple driver update.

Hmmm. So if you're running multiple monitors it uses AMD level power? Non issue in USA where power is dirt cheap.

TechReport was founded by Scott Wasson, now a current AMD employee. My guess the "reader who tipped them off" is either Scott or an Advocate.
For the sake of argument, let's talk about this like it matters.
50W more? OK, so for every 24/7 day (assuming you run your PC 24/7, I do not) that would be 1.2 KWh per day.

Wow, 12 cents per KWh, so that works out to 14 cents a day, 98 cents a week, 52 dollars a year.
Personally it's my opinion that if you actually have to keep track of 98 cents a week, it time to call it quits.
I bet HOMELESS PEOPLE are pretty loose with 98 cents a week, but here is the Tech Report, trying to tell us it's a big deal.
