Bah, the 1.2mW they listed was their consumption, not some rated number based on some regulation i havent heard of. But it does not really matter, as the math is for 1 mW consumed, if a 30mW only use 80% of 30mW then its going to use 24mW.

Then i'm not sure what you're going to be doing with the 3% you're adding, fans, maybe? There's no way a facility is going to be using 240kW of fans, but what if they dont need fans in the first place?

Anyways, the math for the SP50 was already done in the post you replied to, its about twice with S7, which sum up to 70-80PH/s. Albeit perhaps lower than actual 70PH/s if you start factoring in additional electric consumption overall. I can't say my numbers were conservative at all.

If you do simple quick dirty math of 10000 (kW) / 16(kW) you got how many SP50 you fit per mW. Then you multiply that by 110TH/s bam about 70PH/s.

Therefore a mine consuming 10mW would get close to 50% of the new total hashrate. Kinda crazy.

I totally agree with you about not using 240kW of exhaust fans.  IF they are located in a warmer climate, they would use AC for cooling.  IF they are in Iceland, Sweden, etc... they would not need it for AC.  The etc. was mainly for AC but would also include exhaust fans, lighting, etc...  It would probably be more like 100kW for AC and exhaust fans but it depends on the size of the facility.

BY THE WAY, BTCS has 3MW total at their facility in North Carolina with racks prepared for SP50's once they are rolled off the assembly line:  https://www.youtube.com/watch?v=DgHuyItPUfg

If a mining facility had 10MW available for mining [Typically reduced to 80 [IF not 75%] and had gear with similar efficiency and hash rates as that of the SP50, we would come up with the following figure [I will use 100kW for AC, fans, lighting, etc.:

80% of 10MW is 8MW minus 100kW for peripherals = 7,900,000 watts.

7,900,000 watts divided by 16,570 watts each = 476 SP50's

476 SP50's at 110 TH/s each = 53,360 TH/s OR 53.360 PH/s.  The present network hash rate [According to bitcoinwisdom.com/bitcoin/difficulty] is 666 PH/s.

Most every data center [Like BTCS] that tells you, for instance, they have a 3MW facility.  That's what they actually have, not what is available for mining.  Most any data center will tell you they are limited to 75 - 80 percent of their available power.  If their facility had 10MW available for mining, they would tell you.  If they just say their facility is 10MW, I would suspect they can only do 70 to 80 percent of that.  I could be wrong on this but BTCS, for instance, does not say specifically if their "facility" has 3MW available for mining or is it just their facility has 3MW service; of which, only 75 to 80 percent of it can be used within NEC guidelines without Main Service Breakers UL listed at 100% usage.

Hmm. Well, it does not really matter. Not sure where your power for peripherals will go, unless you use millions of RasPi, i think you'll be fine.

And you're right, i added a 0 at the kW for some reason. It would be 1000/16.5=60.60*110 6.6whatever PH/s per mW.

And then Gridseed said they were going to roll out 0.06efficiency i believe? Then that would be about 15 PH/s per mW.

If many manufacturers come out with very power efficient rigs starting spring next year (around March), I can see the S7 becoming equivalent to the way an S5 is right now by block halving IF THE PRICE OF BITCOIN DOES NOT KEEP UP WITH THE DIFFICULTY.

The REAL test will be at block halving.  It will be an interesting last 3 months before block halving with the difficulty and price of bitcoin for sure.
