I've got a little over 7th of neptunes running. Several bad cubes laying around. I haven't been able to figure out where all the excess watts would be coming from either. I'm sure that's showing chip level, but I run 220v so I don't have a kill-a-watt meter for the wall watts.

I didn't bring my crystal ball.... darnit!

Based on the calculations done on the R.I.P. KnC forum, I would say that's roughly around 1982W at the wall.

I used the same calculations to see if I could run 3 Neptune miners on one 30A, 240V breaker and it came out right around the recommended max 80% load. I went ahead and did it and it worked out fine. So, the numbers can't be too far off.

I also use it for calculating how much of the electric bill the miners account for. Subtracting the miners puts me around what the average usage was pre-mining.

If I ever get a clamp meter, I'll be sure to post how the actual numbers compare.

I pull around +/- 1900 watt @ all 500 mhz knc defaults with 470 mhz
so running ~1900w at @ 500 is quite good.

Thanks guys. I'm assuming everyone is also running fans with these miners, right? I've got a fan but it uses like 84watts. Any recommendations on high efficiency fans?

just replaced the fanes of the bonus miners.
with a noctua 3000 rpm fan 4 wire fan.
and a room with an open chimney.
