Redundant AC power supply
Your system supports either:
• Two 495 W, 750 W, or 1100 W (Platinum) AC power supply modules or
• Two 450 W (Bronze) AC power supply modules
NOTE: When two identical PSUs 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 PSUs 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.
CAUTION: If two power supplies are used, they must be of the same maximum output power.
