The R900 is designed with two redundant power supplies. This enables the server to keep running should one power supply go out, or lose power. So yes it will run on one power supply, but you will receive warnings about it on the front LCD, and in open manage.

NOTICE: The system requires one power supply for the system to operate normally.
The system is in the redundant mode when two power supplies are installed and
both power supplies are connected to an AC power source. Remove and replace
only one power supply at a time in a system that is powered on. Operating the
system with only one power supply installed and without a power supply blank
installed for extended periods of time can cause the system to overheat.
NOTICE: If only one power supply is installed, it must be installed in power supply
bay (1).
