I am currently in the process of wiring another 20 AMP 240 VAC circuit to attach my third 16 AMP PDU. This is needed for my third set of four Dell R815 Servers.
My garage mining setup will contain twelve Dell R815 Servers with a mixture of quad 6348 & 6378 Opterons. Also a single SuperMicro Server with dual 6376 Opterons overclocked to 3 GHz.
This is what I have measured for four Dell R815 Servers on one PDU. Two with quad 6348 and two with quad 6378 Opterons.
On the current CN/R algorithm:
6866.8 H/s 2880 watts (12 Amps * 240 VAC) avg of 720 watts per server measured at the panel. 9.2c per KWH
This setup would be mining for a loss of $4.18 a day which is why these have been powered off and will stay off until the November 30th fork.
