Dell OptiPlex 3020 / 7020 / 9020 MT 290W Power Supply

Dell OptiPlex 3020 / 7020 / 9020 MT 290W Power Supply

The Dell OptiPlex 3020 / 7020 / 9020 MT 290W Power Supply is an internal replacement PSU designed for compatible Dell Mini Tower desktop systems. It is suitable for replacing a failed, unstable or damaged original power supply while maintaining the correct Dell power connector layout and chassis fit.

This PSU is commonly used in business-class Dell desktops where reliability and compatibility are more important than using a standard aftermarket ATX power supply. Since Dell uses proprietary motherboard power connections on these systems, the exact PSU model, connector arrangement and physical size should always be matched before replacement.

290W Power for Dell Mini Tower Systems

The power supply delivers up to 290W of total output, which is suitable for standard Dell OptiPlex Mini Tower configurations using compatible Intel processors, DDR3 memory, SATA storage and low-power expansion hardware.

It is designed for normal office and business workloads rather than high-power gaming configurations.

Dell Proprietary 8-Pin Motherboard Connector

The OptiPlex 3020, 7020 and 9020 MT systems use Dell’s proprietary 8-pin motherboard power connection instead of a standard 24-pin ATX connector.

For this reason, the replacement PSU should match the original Dell connector and pin configuration to ensure safe operation.

Dedicated 4-Pin CPU Power Connection

A separate 4-pin CPU power connector supplies power to the processor section of the motherboard. Both the main 8-pin connection and CPU power connector are essential for proper system startup and stability.

Mini Tower Internal Design

This PSU is built for Dell Mini Tower chassis and fits the larger MT form factor used in the OptiPlex 3020, 7020 and 9020 series. The built-in cooling fan helps manage heat while maintaining airflow inside the desktop.

Compatible with Multiple Dell OptiPlex Models

Compatible PSU revisions are used across selected Dell OptiPlex 3020 MT, 7020 MT and 9020 MT systems. However, Dell may use different OEM manufacturers and part numbers, so the safest method is to match the original PSU label, wattage, Dell DP/N, connectors and mounting size.
