Power supply units
Your system supports one of the following:
Two 495 W, 750 W, or 1100 W AC power supply modules or
Two 1100 W DC power supply modules or
Two 750 W mixed mode power supply modules
NOTE: Titanium power supply unit is nominally rated for 200 VAC to 240 VAC input only.
NOTE: When two identical power supplies are installed, power supply redundancy (1+1 – with
redundancy or 2+0 – without redundancy) is configured in system BIOS. In redundant mode, power
is supplied to the system equally from both power supplies when Hot Spare is disabled. When Hot
Spare is enabled, one of the PSUs will be put into standby when system utilization is low in order to
maximize efficiency.
NOTE: If two power supply units are used, they must be of the same maximum output power.
NOTE: For AC power supply units, use only power supply units with the Extended Power
Performance (EPP) label on the back. Mixing power supply units from previous generations of
servers can result in a power supply unit mismatch condition or failure to power on.
