PSU issues with Dell Poweredge r6515 Server

Hi All,
We bought a set of three heavily configured Dell R6515s with dual 700W power supplies. When powered by 120V, the servers are not capable of redundant operation. Well, more precisely, they boot and stop on a BIOS screen that warns of insufficient power.
When digging in a bit more, I can see in the iDrac web interface that the supplies show they are capable of 700W output, but are only outputting 550W.
This happens because the supplies require 200+ volts to be efficient enough to output the full 700W.
I've attached two iDrac screenshots (links) to show this: one at 120 V and the other at 240 V. These are the same power supplies and the same server, just different input voltages.

Hopefully, this saves anyone who sees [this](https://www.reddit.com/r/sysadmin/comments/yayiog/psu_issues_with_dell_poweredge_r6515_server/) thread from [this](https://xkcd.com/979/).
