My backup says I used 109 kw last month. So right around 3.5kwh a day. Which is worlds away from 3kwh in a few renders over a few hours... 

With all the things I have hooked to it that sounds about right. That just over 13 bucks to run almost all of the electronics in the house for a month. Or 32 bucks at 30 cents a kwh... I also test Poser daily, and have beta tested it for years. System's don't pull 500 watts all day long, and the one in question should not peak at that either. It should not go over 300-350 max.

I have played around with my system in the last hour or so and the most I have seen power draw is just over 300 watts while rendering with 1024 size buckets in Optix..

And they are very similar systems, to a point.

If the op's system is using 500 watts, something is drastically wrong with if it is an 11th gen I7 system with a 3060.....

Or, the measurements and math are way off..... 

My backup retails for 2 grand, it is an SMT3000.... 

It is not just a simple kv meter plugged into a socket and the control center software (Powerchute Business), will track everything, down to the penny.... It is scary accurate...

I do give the op credit for tracking it, and the information provided about the insane cost of electricity there. 

But there is no way that 5 or 6 test renders use 3kwh as claimed. I seriously question the math used, and the meter that states the system pulls that much power.

The story seem to change as well, but I will chalk that up to a language barrier.....
