On: Is it okay to daisy chain a UPS?

most electronics don't need pure sine waves as they are converting the ac to DC anyway. but perhaps a square wave could throw off some PSUs.

Good point.

I ran a lot of gear through a decent separate PDU and the rack of datacenter gear refused to die. No burst transistors or other things that can be the norm after.

My comment was definitely based in this - providing the cleanest electricity possible, however, doesn't hurt, and can only help.
