It should... seriously :)

I've 'walked' 7200s onto new/redundant power feeds like you described here 
and had no issues with power.  You definitely need to make sure the second 
PS is seen correctly like you did with the 'sho env all'.

Worst comes to worst, schedule the power move during a maintenance window 
and if the router accidentally gets power-cycled, that's your 'oops' 
condition :)
