CONFIGURING the SERVER
STEP 8 ORDER POWER SUPPLY
The C220 M3 SFF server accommodates two power supplies. A lightly loaded server can operate
from one 650 W power supply. A fully loaded server might need to be powered with two 450 W or
two 650 W power supplies (see
Table 15).
Use the power calculator at the following link to determine the needed power based on the
options chosen (CPUs, drives, memory, and so on):

required is 650 W (UCSC-PSU-650W). See
