Power supplies

Your system supports:
  • Two 495 W, 750 W, or 1100 W AC power supply modules
  • Two 750 W DC power supply modules
    • When two identical power supplies are installed, the power supply configuration is redundant (1 + 1). In redundant mode, power is supplied to the system equally from both power supplies to maximize efficiency.
    • When only one power supply is installed, the power supply configuration is non-redundant (1 + 0). Power is supplied to the system only by the single power supply.
    • When configured in a 2+0 configuration, 1+1 redundancy will not be supported.
  • NOTE: If two power supplies are used, they must be of the same type and must have the same maximum output power.
  • NOTE: For AC power supplies, use only power supplies with the Extended Power Performance (EPP) label on the back. Mixing power supplies from earlier generations of Dell PowerEdge servers can result in a power supply mismatch condition or failure to power on.
