Redundant AC Power Supply

Your system supports up to two 495 W or 750 W redundant AC power supplies.

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.

  • NOTE: If two power supplies are used, they must be of the same type and have the same maximum output power.
  • NOTE: Redundant power supplies are supported on systems with hot-swappable hard drives only.
  • NOTE: When selecting or upgrading your system configuration, verify the system power consumption with the Dell Energy Smart Solution Advisor at dell.com/ESSA to ensure optimum power utilization.
