I got some more mining porn today. 
Very nice!!!
Are you using the 2000w server PSUs? How many S3s can they safely handle?
Thanks!
Yes I am using the DPS2000-BB's. I am running 4 S3's per PSU. I bet I could run more but I only have 8 PCIE cables per PSU.
I am pulling 33 amps @ 240V for 24 of them so 330W each. That is only 1320W per PSU. I could put 2 more easy on each PSU if I made new cables with more PCIE connectors.
