We currently use DC power supplies, but non-redundant http://www.solaheviduty.com/products/powersupplies/sdp.htm. We use terminal strips to distribute the power. For us to change, we just replace the power supplies with this... http://www.solaheviduty.com/products/powersupplies/sdnpred.htm. That has the rectifiers and diodes in place with LED status indicators to show the status of the power. Then you can put them in parallel and put 2 UPSs in place for failure and surge suppression.

My experience has been less then perfect with APC. The 19" rack ones have been pretty good but the small 7 amp, 11 amp, tiny desktop models have gone bad on me.
