I'm using an HP server power supply capable of 42 amps on the 12 volt line per blade, so 4 total
And I'm using one 12 gauge wire for 12v and one for geound, which is roughly equal to 3x 16 gauge wires
Wire doesn't heat up and makes it much easier to install the miner
Also ordered 2 extra fans for my 2 antminers, same exact fan as the original one
overall it's a very good machine
I freaked out when I saw a lot of x's in the ASIC status
But a few power downs, wait 30 seconds and powering on fixed that
Right now both units show full oooooooo on that screen

The stuck at etc/config/cgminer issue is the unit not being able to connect to an NTP server
I could not connect to any of the 4 that come pre configured
I used time-a.nist.gov and that worked
I'm in the east coast (DC) so not sure if this is also good for the west coast guys
But just google NTP server and a whole bunch of servers
Try to pick the closest one
