The PowerEdge R550 supports up to 2 AC or DC power supplies with 1+1 redundancy, autosensing and auto-switching
capability.
If two PSUs are present during POST, a comparison is made between the wattage capacities of the PSUs. In the event that the
PSU wattages don't match, the larger of the two PSU's is enabled. Also, there is a PSU mismatch warning displayed in BIOS,
iDRAC or on the System LCD.
If a second PSU is added at run-time, in order for that particular PSU to be enabled, the wattage capacity of the first PSU must
equal the second PSU. Otherwise, the PSU will be flagged as unmatched in iDRAC and the second PSU will not be enabled.
Dell PSUs have achieved Platinum efficiency levels as shown in the table below.
