The plan is to put it all on 240 volt, to balance out the load across L1 and L2 I just haven't had time to finish it all.
I am tempted to move it back to where it came from to see if the one power supply works. Interestignly enough, the plug I plugged it into has nothing else on it, and it is a plug right at the panel box, so it is significantly closer than the one in the garage.
Chances are its not your power as much as its the apw3++ psu. People have had problems with them running on 220v let alone 110v. The efficiency has a +/- range and I think its mostly minus. I would use 2 Hp server psus if I needed to run on 110v.
