Received the two DPS830 power supplies in today. I first just installing one in the server with a DPS-730 and the server did not really want to boot up. Pulled the 730 out and it booted up just fine with the 830 so I added the 2nd 830 and added the 730 to the other server. All is working just fine.
Guess the answer is Yes it will work but you can not mix the two.
Hope this helps someone in the feature.
