I was using an Xconnect, which was supposed to be pretty good.  A new 
one is about to be RMA'd from my supplier.

In the meantime, I got a Uneeq 500W supply, reran rescue mode and 
manually wrote the partition table to the MBR with fdisk.  Everything 
booted A-OK, so I guess I'll subsist on a substandard PS until the 
Xconnect comes in.

Thanks everyone for your help.
