Did some testing today with the batch 9 s7's that i just got. was wondering if any one has the same results?

So currently I don't have the Bitmain psu's just yet so i'm powering them with (2) 1000watt EVGA SuperNOVA G2's 5 Cables in each.
So far all 6 miners are giving me the same results so at least the power draw is consistent across the board.

I tested these on 2 currents- 208volt and 120volt Got different results in Amp Draw though

On 208 Volt I'm Seeing a 7 amp power draw per miner- which puts the watts at around 1450watts

On 120 Volt I'm seeing a 12 Amp Power draw per miner- Which puts the watts a little bit lower at 1440watts

Now on Bitmains website they list it as 1293+10% well 10% of 1300 is 130 add those two together and you get 1430 Which is pretty close to what im seeing on the pdu's

Let me know what you guys have found out with your own gear!

Thanks, Keegan!

This is not new news on this. Batch 8 was designed the same (besides io board). They really do mean +10 percent.

Some of the earlier generations had more chips. And they got better efficiency. But b8 and b9 less chips and more freq = less power efficiency.
