Dell 4 Power, Thermal, Acoustic 4.1 Power Supplies The R410 is powered by a non-redundant 480 W power supply (Dell P/N F238K) and redundant 500 W power supply (Dell P/N F649J). The power supply has automatic input voltage detection. An auxiliary power-out receptacle is not provided on this unit. The power supply in the chassis has been rated as 82%, efficient at 20%, and 100% load, and 85% efficient at 50% load under 115V AC input line. Redundant power efficiency is 88% at 20% load, 100% load, 92% efficiency at 50% load under 230V AC input line. The base system includes a single 480 W power supply. This unit provides power to the PowerEdge R410 planar, the four internal hard drive bays, and one slim optical disk drive bay. Power is softswitched allowing power cycling via a switch on the front of the system enclosure or via software control (through server management functions). The power system is compatible with industry standards, such as ACPI and Server 2000. The VRD is integrated onto the planar and is not field upgradeable. The VRD follows Intel's VRD11.1 specification. The PowerEdge R410 uses a four-phase design. 4.2 Power Supply Specifications Single - 480 W power supply Redundant - 500 W power supply There are two separate power supply connectors on the planar: an ATX connector (2x12) and a 2x4 connector to provide an additional two pins for +12V. (The ATX connector pin definition is not standard, and it defined by power rating calculation). The 2x12 ATX connector provides 3.3V, 5V, 12V, and 12V standby to the system. The 5V standby is provided to the system via a charge pump from 3.3V standby. PowerEdge R410 Technical Guide 24

4.1
Power Supplies
The R410 is powered by a non-redundant 480 W power supply (Dell P/N F238K) and redundant 500 W
power supply (Dell P/N F649J).
The power supply has automatic input voltage detection. An auxiliary power-out receptacle is not
provided on this unit.
The power supply in the chassis has been rated as 82%, efficient at 20%, and 100% load, and 85%
efficient at 50% load under 115V AC input line. Redundant power efficiency is 88% at 20% load, 100%
load, 92% efficiency at 50% load under 230V AC input line.
The base system includes a single 480 W power supply. This unit provides power to the PowerEdge
R410 planar, the four internal hard drive bays, and one slim optical disk drive bay. Power is soft-
switched allowing power cycling via a switch on the front of the system enclosure or via software
control (through server management functions). The power system is compatible with industry
standards, such as ACPI and Server 2000.
The VRD is integrated onto the planar and is not field upgradeable. The VRD follows
Intel’s VRD11
.1
specification. The PowerEdge R410 uses a four-phase design.

There are two separate power supply connectors on the planar: an ATX connector (2x12) and a 2x4
connector to provide an additional two pins for +12V. (The ATX connector pin definition is not

The 2x12 ATX connector provides 3.3V, 5V, 12V, and 12V standby to the system. The 5V standby is
provided to the system via a charge pump from 3.3V standby.
